Attribute of objects forming various screens, that is, an object storage area E _{OBJ in} which object code data representing the object type and its display coordinate position is stored, object image data corresponding to these object codes, and a background forming a screen background Image data storage area E for storing image data
_IMAGE and each image data are color data (RGB data)
There is provided a look-up table storage area E _{CLT in} which a color look-up table to be converted into a color table is stored. The data structure of these storage areas will be described below.

[0022] With reference to diagram 3 to FIG. 4 of the object memory area E _OBJ configuration of the object memory area E _OBJ will be described. In this storage area E _OBJ , object codes for various screens, which will be described later, are allocated and stored. There are two types of object codes: an object A that is fixedly displayed on the screen and an object B that is moved and displayed on the screen according to the operation of the cross key 109 or the enter key 111 described above. That is, in the initial screen object code OBJ1 and the total control screen object code OBJ5, only the object A codes OBJ1 _OBJA and OBJ5 _OBJA which are fixedly displayed on the screen are stored. Object code OBJ2 corresponding to other screen
In OBJ3, OBJ4, OBJ6 and OBJ7, two types of codes are stored: an object A fixedly displayed on the screen and an object B moved and displayed.

Here, the data formats of the object A code OBJA and the object B code OBJB stored in the above-described form will be described with reference to FIGS. 5 and 6. In the OBJA / OBJB code, one word forms three object words W0 to W2 each having a 16-bit length to form one object attribute. The object attribute represents the size (area) of the corresponding image data, the display position coordinates, the character name, the color block used (described later), and the like.

As shown in FIG. 5 or FIG.
The lower 9 bits (bit 0 to bit 8) of the words W0 and W1 of the JA code / OBJB code represent the display position coordinates (X, Y) on the object surface. The object plane is a dot plane defined by the coordinate area of (0,0) to (511,511). Object surface OBJA
In (or OBJB), the area of 336 dots in the horizontal direction and 224 dots in the vertical direction (scanning line) sharing the origin (0, 0) is the display surface. The display position coordinates (X,
Y) represents the position of the upper left corner in the object area. When the object position defined by the display position coordinates (X, Y) does not fall within the area of the display surface, the object is hidden.

An inversion flag X indicating whether to invert the corresponding image data is set in bit 9 of the word W1 in the OBJA code. This flag X specifies whether the writing order when storing the object image data in the line buffer is the address order or the reverse order thereof. When it is "0", the address order is specified, and "1" is specified. When ", specify the reverse order. Therefore, the right and left of the normal image written in the address order and the image written in the reverse order are opposite to each other, and both images have a mirror image relationship. That is, it is possible to form two images, one for displaying one image data normally and one for displaying in reverse. By doing so, it is possible to increase the types of images that can be displayed in a system with a small memory capacity. It has become.

The size of the object area is formed by a minimum of 8 dots × 8 dots, and the area is composed of words W0 and W1.
The vertical and horizontal sizes (X size, Y size) can be variably designated by the upper 4 bits (bit 12 to bit 15) of the. For example, when the X size is "0", the width of the object is 8 dots, when it is "1", it is 16 dots, and when it is "15", the maximum width is 128 dots. Top 4 in word W2
Bits (bit 12 to bit 15) specify a color block of a color look-up table unit 65 described later to determine the type of display color, and the lower 12 bits after bit 12 are set with a character name indicating the character type of the object. To be done. The color block is a block in which a color lookup table CLT, which will be described later, is divided into blocks of a predetermined number of colors and a color code is assigned.

[0027] In the image data storage area E _IMAGE configuration image data storage area E _IMAGE, similar to the storage area E _OBJ as described above, as shown in FIG. 7, the image data of each type of screen is stored in assignment. The image data includes background image data forming a screen background, object A image data whose type and display coordinate position are designated by the object A code, and object B whose type and display coordinate position are designated by the object B code. Image data is classified into three types. That is, as shown in FIG. 7, the image data IM1 of each screen is displayed.
.. to IM5 are assigned any one of the above three types of image data to form a screen. The three types of image data form a BG screen, an OBJA screen, and an OBJB screen, respectively, and these screens overlap to form one display screen. In the case of this embodiment, the OBJB screen is given the highest priority, followed by the OBJA screen and the BG screen in this order. Therefore, the overlapping order is OB at the front.
The JB screen is arranged, and then the OBJA screen and the BG screen are arranged in this order on the back side.

As shown in FIG. 8, the object B image data is formed in a cell unit consisting of 8 dots in the vertical direction and 8 dots in the horizontal direction. A 1-bit color code is assigned to each dot forming one cell, and when it is "0", it becomes a transparent code. As shown in FIG. 9, the color code for one cell is represented by four words, that is, each word has a 16-bit length, that is, words C0 to C3. That is, the color code of the dot rows d0 to d7 in one cell is stored in the upper 8 bits of the word C0, and the next dot row d1 is stored.
0 to d17 are stored in the lower 8 bits of word C0.
After that, each dot row d20 to d27, d30 to d37,
,, d60 to d67, d70 to d77 are the same as the word C

Is a control register that determines the operation mode of. The control register 53 is a register having a total length of 16 bits, and the display control mode is set according to the register value set at each bit position by the CPU 1.

A character generation memory 54 stores the object B image data forming the object OBJB. The image data stored in the memory 54 forms "characters", and is formed in cell units of 8 dots in the vertical direction and 8 dots in the horizontal direction as shown in FIG. A 1-bit color code is assigned to each dot forming one cell, and when it is "0", it becomes a transparent code. On the other hand, the object A image data forming the object OBJA stored in the above-mentioned VRAM 6 has a vertical direction of 8 dots × a horizontal direction of 8 dots, as shown in FIG.
Although dots are formed in units of one cell, in this case, a 4-bit color code is assigned to each dot, and an image that can be displayed in 16 colors including a transparent color is obtained.

Reference numeral 55 is a DMA controller for controlling DMA transfer according to an instruction from the CPU 1. The DMA controller 55 responds to the transfer instruction from the CPU 1 by the above-mentioned R.

The selection item display area displayed in the lower half of the band screen is moved to the display area B, and instead, the portrait images for three persons are selected from the portrait images for a plurality of persons arranged in the display area B. Select and display the image. FIG.
9 shows such a state. by the way,
The portrait images P1 and P2 shown in FIG. 19 are formed by the same object A image data, and the inversion flag X in the above-mentioned OBJA code is set to "1" when one of the images is generated. As a result, two images related to the mirror image in which the left and right of the image are reversed are obtained. Even in such a band member change screen, a portion that does not change in display is formed by the object A image (OBJA), and a character string that changes in display is formed by the object B image (OBJB).

Structure of Genre Selection Screen On the genre selection screen, as shown in FIG. 20, a window WIN used for selecting a performance genre is displayed in the center of the screen. This window WIN is shown in FIG.
As shown in FIG. 1, objects OBJA-1 to OBJA8 that form a title character and objects OBJA-50 and OBJA- that display a scrollable state.
Title bar (object OBJA) where 51 is placed

JA-51 to OBJA-60).

Each button (object OBJA-51-
In OBJA-60), 18 columns of objects OBJB having a size of 8 dots × 8 dots are arranged per row. That is, the objects OBJB-128 to OBJB-27
1 are arranged in a matrix. These objects O
BJB-128 to OBJB-271 form characters or are made transparent, and are set to a higher display order than the above objects OBJA-51 to OBJA-60. Therefore, it looks like a string is drawn on the button. In addition, each button is
By _changing the color block number of the color look-up table CLT3 _OBJA (see FIG. 14) described above, the display color can be changed according to the operation of the up and down keys of 9.

Structure of Band Save Screen On the band save screen shown in FIG. 22, the window WIN similar to that described above is also arranged. In the window WIN on the van save screen, the character string can be rewritten by changing the type of the object OBJB forming the character on each button. At that time, the object O
The display color of BJB is the color block number of the color lookup table CLT3 _OBJB shown in FIG.
It is possible to change from (black) to # 2 (pink) and display that rewriting is in progress.

Structure of Total Control Screen Next, FIG. 23 is a diagram showing an example of the total control screen. On this screen, a “button” for setting various operating conditions of the apparatus 100 is formed by the object A. As shown in FIG. 24A, each button is configured to be in three states: a normal state (a) that looks concave, a select state (b), and an active state (c) that looks convex. . That is, as shown in FIG. 24B, OBJA-A forming the upper left edge of the button, OBJ-B forming the lower right edge of the button, OBJA-C forming the central portion of the button, and on the button. OB that forms characters
A button is formed by JA-D and E, and these objects OBJA-A to OBJA-are set according to the contents of the setting operation.
The display color of C is changed to represent the above states (a) to (b).

For example, "RESUME" in the figure will be described as an example. First, with the unset button, the color data D13, D14, D15 in the color block number # 0 of the color look-up table CLT4 _OBJA are assigned to the objects OBJA-A to OBJA-C, respectively, and a normal state that looks concave ( a).
When a button is selected in this state by operating the left and right keys of the cross key 109, the objects OBJA-A to OBJA-
Color data D13, D1 of color block number # 8 in C
4, D15 is assigned and the display color is changed to show the selected state (b). When the enter key 111 is pressed to confirm the setting, the objects OBJA-A to O
Color data D1 of color block number # 7 in BJA-C
3, D14 and D15 are assigned so that the convex state looks like an active state (c). By doing so, it becomes possible to realize a GUI operation environment as if a button was clicked without providing a pointing device such as a mouse.

C. Operation of the Embodiment Next, the operation of the embodiment having the above configuration will be described with reference to FIGS. In the following, the outline of the overall operation will be described first, and then the details of the image processing related to the gist of the present invention will be sequentially described.

(1) Overall Operation (a) Schematic Flow When the power switch 102 of the apparatus 100 of this embodiment is turned on, the CPU 1 operates according to the flow shown in FIG. That is, when the power switch 102 is turned on, the process proceeds to step SA1 and RAM3, VRAM6, VDP5.
The registers and flags provided in each part of the sound source 8 are reset to zero, and initial values are set. Then, the process proceeds to step SA2. In step SA2, the keyboard 101 and the panel switch group are scanned to detect a key release operation event or a switch operation event,
The tone generation is performed according to the detected event, and the tone generation process / music process for setting various performance parameters when the tone is generated is performed, while the image process for generating the screen display corresponding to these processes is executed.

Then, when step SA2 is completed, C
PU1 advances the processing to step SA3, and determines whether or not the auto power off setting is made. Here, if it is not in the power-off state, the determination result is "NO", and the process returns to step SA2 to continue the main flow process. On the other hand, when the power-off is set, the determination result is "YES".
Then, the process proceeds to the next step SA4. In step SA4, for example, a resume process of saving the setting state of each unit in the device 100 in the memory, a mute process of muting a musical sound being sounded, and the like, and a power-off process of turning off the power are executed to stop the operation.

(B) Main Flow When the processing of the CPU 1 proceeds to step SA2 described above, FIG.
The main flow shown in FIG. 6 is executed and the process proceeds to step SB1. In step SB1, a keyboard scan is performed in order to detect a key pressing operation of the keyboard 101. Then, step SB2
Then, performance information such as key-on, key-off, key code, and velocity is generated based on the key release operation event detected in the keyboard scan, and sound generation processing is instructed to instruct the sound source 8 to generate a musical sound according to the performance information. Next, in step SB3, the panel switch 10
In order to detect the switch operation of 3-111, a panel switch scan is performed and a switch operation event is generated.

Next, in step SB4, a switch operation for creating time-series automatic performance information is extracted from the generated switch operation events to create an event matrix.
This event matrix is a rhythm pattern in which tone generation timings are listed when automatic rhythm performance information is created, and is a performance pattern including pitch and tone generation timing when automatic performance information is created. Next, when proceeding to step SB5, the CPU 1 performs a music process for setting an effect form to be given when the rhythm pattern or performance pattern represented as the event matrix is generated as a musical tone. After that, the CPU 1 performs image processing related to the gist of the present invention, that is, performs display control so as to generate a screen corresponding to the above-described switch operation event, and in the subsequent step SB7, other system processing is performed to complete the main flow. To do.

(2) Image Processing Operation Next, the details of the image processing executed in step SB6 will be described in detail. When the process of the CPU 1 proceeds to step SB6, the image processing routine shown in FIG. 27 is activated, and the process proceeds to step SC1. Step SC
At 1, it is determined whether or not there is mode switching, that is, whether or not a switch operation event for changing the screen display has occurred. Here, if there is a switch operation event for changing the screen display, the determination result is "YES", and the process proceeds to the next step SC2. If not, the process proceeds to step SC3 described later. When the processing proceeds to step SC2, the CPU 1 follows the contents of the screen to be switched,
A screen switching process of extracting the corresponding object code from the object and storing it in the object memory 52 inside the VDP 5 is executed. The details of the screen switching process will be described later.

Next, in steps SC3 to SC6, display control corresponding to the switch operation event occurring in each screen mode is performed. That is, in step SC3, the cross key 109 and the escape key 1 described above are used.
10 or the character strings CHR1 to CHR1 displayed on the band screen (see FIG. 18) in response to the operation of the enter key 111.
Change the display mode of CHR8. Next, step SC4
Then, display control is performed in which the character string in the window WIN displayed on the genre select screen (see FIG. 20) is moved and displayed or the color is changed according to the operation of the cross key 109 or the enter key 111. Then, in step SC5, display control is performed in which the display color of the "button" for each item on the total control screen (see FIG. 23) is changed according to the switch operation. Further, in step SC6, the cross key 109 is displayed on the band save screen (see FIG. 22).
Or the window WIN depending on the operation of the enter key 111
Display control is performed to move and display the character strings in or change the color.

Details of the display control performed in these steps SC3 to SC6 will be described later. Also, a CP that executes the display control in steps SC3 to SC6.
U1 interrupts a V blank interrupt processing routine (described later) at regular intervals to update the display-controlled screen. That is, in the process of executing steps SC3 to SC6, the CPU 1 executes the V blank interrupt processing routine in synchronization with the vertical blanking period on the display DP side to execute the object code, the image data and the color look necessary for the screen display. VDP5 up table
Or DMA transfer to the VRAM 6 side. Then, in the VDP 5, the screen is updated based on the above various data DMA-transferred to the VRAM 6, the character generation memory 54, and the object memory 52 inside itself.

(A) Operation of Screen Switching Processing Routine Next, the operation of the screen switching processing routine will be described for each screen. Switching to Initial Screen As described above, when a switch operation event for changing the screen display occurs, the CPU 1 executes the screen switching processing routine shown in FIG. 28 via step SC2 and advances the processing to step SD1. In step SD1, it is determined whether or not the generated switch operation event is an instruction to switch to the initial screen. Here, if the event is an instruction to switch to the initial screen, the determination result in step SD1 is "YES", and the CPU 1 determines in step SD2.
Proceed to. In step SD2, the register IGF
The value of the initial screen transfer flag stored in is set to "1".

Next, when proceeding to step SD3, the ROM
Initial screen object code OB stored in 2
J1 (see FIG. 3) is stored in the work area of RAM3. By doing so, the background image data forming the initial screen, the object A image data, and the initial screen CLT data CL are formed by the V blank interrupt processing routine described later.
T1 is transferred to the VRAM 6 and VDP 5 sides, whereby the initial screen is updated and displayed.

Switching to the band screen When a switch operation event for instructing the switching to the band screen occurs, the determination result of step SD1 becomes "NO", and the process proceeds to step SD4 to determine whether to switch to the band screen. To judge. And in this case,
Since the screen is switched to the band screen, step SD4
The result of the determination is "YES", and the process proceeds to the next step SD5. At step SD5, the value of the band screen transfer flag stored in the register BGF is set to "1". Next, when proceeding to step SD6, the band screen object code OBJ2 stored in the ROM 2
(Refer to FIG. 3) Code OBJ2 for object A
_OBJA is extracted and stored in the work area of _RAM3 .

Subsequently, when proceeding to step SD7, the CPU
1 is the band screen object code OBJ2 (FIG. 3) stored in the ROM 2 as in step SD6.
The code B OBJ2 _OBJB for the object B is extracted from the above (see) and stored in the work area of the RAM 3. Then, in the V blank interrupt processing routine described later, the band screen image data IM2 (see FIG. 7) and the band screen CLT data CLT2 (see FIG. 12) that form the band screen during the vertical blanking period are V.
A band screen is formed by transferring to the RAM 6 and VDP 5 side.

Switching to genre select screen Next, when a switch operation event instructing switching to the genre select screen occurs, the above step SD
The determination results of 1 and SD4 are both "NO", and the process proceeds to step SD8 to determine whether to switch to the genre selection screen. In this case, since the screen is switched to the genre selection screen, step SD8
The result of the determination is "YES", and the process proceeds to the next step SD9. At step SD9, the value of the genre select screen transfer flag stored in the register JSF is set to "1". Next, in step SD10, the object A code OBJ4 _OBJA is extracted from the genre select screen object code OBJ4 (see FIG. 3) stored in the ROM 2 and stored in the work area of the RAM 3.

Then, when proceeding to step SD11, the CP
Similarly to step SD10, U1 extracts the object B code OBJ4 _OBJB from the genre select screen object code OBJ4 (see FIG. 3) stored in the ROM 2 and stores it in the work area of the RAM 3. As a result, based on the V blank interrupt processing routine described later, the image data IM3 (see FIG. 7) forming the genre select screen and the CLT data CLT3 for the genre select screen CLT3 (see FIG. 1) during the vertical blanking period.
2) is transferred to the VRAM 6 and VDP 5 sides, and the genre select screen is updated.

Switching to the total control screen When a switch operation event for instructing switching to the total control screen occurs, the above step SD1,
The determination results of SD4 and SD8 are both "NO",
The process proceeds to step SD12 to determine whether to switch to the total control screen. And in this case,
Since the screen is switched to the total control screen, the determination result in step SD12 is "YES", and the process proceeds to the next step SD13.

At step SD13, the value of the total control screen transfer flag stored in the register TCF is set to "1". Next, when proceeding to step SD14, the total control screen object code OBJ5 (see FIG. 3) stored in the ROM 2 is stored in the RAM.
Store in work area 3 As a result, the image data IM4 (see FIG. 7) forming the total control screen and the CLT data CLT4 for the total control screen CLT4 (see FIG. 12) during the vertical blanking period are stored in the VRAM6 based on the V blank interrupt processing routine described later.
And the total control screen is updated by being transferred to the VDP5 side.

Switching to the band save screen When a switch operation event instructing switching to the band save screen occurs, the above steps SD1 and SD
The determination results of 4, SD8 and SD12 are all "NO", and the process proceeds to step SD15 to determine whether to switch to the band save screen. In this case, the screen is switched to the band save screen, so step S
The determination result of D15 is "YES", and the next step S
The process proceeds to D16. At step SD16, the value of the band save screen transfer flag stored in the register BSF is set to "1". Next, in step SD17, the object A code OBJ6 _OBJA is extracted from the band save screen object code OBJ6 (see FIG. 3) stored in the ROM 2 and stored in the work area of the RAM 3.

Then, in step SD18, as in step SD17, the object save code OBJ6 _OBJB is extracted from the band save screen object code OBJ6 (see FIG. 3) stored in the ROM 2 and stored in the RAM3. Store to work area. As a result, the image data IM5 (see FIG. 7) forming the band save screen and the band save screen CLT data CLT5 (see FIG. 12) during the vertical blanking period are stored in the VRAM 6 and the VRAM 6 based on the V blank interrupt processing routine described later. It is transferred to the VDP5 side and the band save screen is updated. It should be noted that, when another event different from the event for instructing screen switching occurs, the above-mentioned step SD
The determination results at 1, SD4, SD8, SD12 and SD15 are all "NO", and the CPU 1 completes this routine.

(B) Operation of Band Screen Processing Routine When the screen switching processing routine is completed in this way, or when an event other than screen switching occurs, the CPU 1 executes the band screen processing routine shown in FIG. 29 through step SC3 described above. Is executed to proceed to step SE1. In step SE1, it is determined whether or not the currently displayed screen is a band screen. Here, when it is not the mode for displaying the band screen, the determination result is “NO”, and this routine is completed. On the other hand, when the band screen is displayed, the determination result is "YES", and the process proceeds to the next step SE2. When the process proceeds to step SE2, the CPU 1 determines whether the generated event is an event that requires image change.

The event requiring image change is, for example,
When the character string CHR1 on the band screen (see FIG. 18) is selected according to the up / down key operation of the cross key 109,
This refers to the operation of changing band members that replace the portrait images of musicians displayed for each part. Then, when an operation that requires image change is performed, the determination result of step SE2 is “YES”, and step S2 is performed.
The process proceeds to E3. On the other hand, when an operation that does not require image change is performed, the determination result is "NO", and this routine is completed.

When an operation that requires an image change is performed, the CPU 1 advances the processing to step SE3, and determines whether or not the event that has occurred changes the character string. Here, for example, if the up or down key of the cross key 109 is operated to scroll the cursor position to select any one of the character strings CHR1 in the band screen (see FIG. 18), the determination result is “YES”. Then, the process proceeds to the next step SE4. In step SE4, a character string change processing routine (described later) for selecting one of the character strings CHR1 in accordance with this scroll operation is executed. Next, in step SE5, the color block number associated with the selected character string (object OBJB) is rewritten, and a color block change processing routine (described later) for changing the display color of the character string is executed, and then this routine is executed. To complete.

On the other hand, when the result of the determination in step SE3 is "NO", that is, when an operation other than character string change is performed, the process proceeds to step SE6. In step SE6, it is determined whether or not the performed operation is an operation of changing the band member, that is, an operation of changing one of the portrait images of the musicians displayed on the band screen with another. To do. Then, when the operation is performed, the determination result here becomes "YES", and the process proceeds to the next step SE7. In step SE7, the portrait image of the part designated to be changed is displayed at the designated coordinate position, and the display color of the "part name" portion arranged below the portrait image to be changed is changed. A change processing routine (described later) is executed to complete this routine.

(C) Operation of Character String Change Processing Routine As described above, the cursor position is scrolled by operating the up key or the down key of the cross key 109 in order to select any one of the character strings CHR1 in the band screen. And CP
U1 executes the character string change processing routine shown in FIG. 30 through step SE4 and advances the processing to step SF1. In step SF1, the scroll direction operated is determined. When the scroll direction is "up", that is, when the up key of the cross key 109 is operated, the process proceeds to step SF2, and the Y-direction address indicating the display area on the ROM 2 is decremented by one line.

That is, the code OBJ2 for the object B that forms a character that can be moved and displayed on the band screen.
_OBJB is stored in the object storage area E _OBJ of the ROM 2 in a form that matches the display form on the screen. The storage area is 18 character strings in X direction (column direction), Y
There are 6 lines in the direction (row direction), and this is the character string CHR.
The screen is displayed as 1. Therefore, when the upper key of the cross key 109 is operated to scroll to the upper side of the screen, the Y-direction read address of the OBJB code in the storage area is decremented by one. Similarly, when the lower key of the cross key 109 is operated to scroll to the lower side of the screen, the above step S
Based on the determination of F1, the process proceeds to step SF3, in which case the Y-direction read address is incremented by 1.

Then, in step SF4, the CPU
Reference numeral 1 designates the current address (X, Y) updated according to the scroll operation as a read start pointer. Then, in the next step SF5, "1" is set in the pointer register i. The value of the pointer register i is sequentially incremented as will be described later and treated as a relative address based on the read start pointer. Then, in step SF6 and thereafter, 18 character strings × 6 from the storage area based on the scrolled cursor position.
The OBJB code for the row is read according to the value of the pointer register i. That is, in step SF6, it is determined whether or not the OBJB codes for 18 character strings and 6 lines have been read. Here, when the OBJB code for 18 character strings and 6 lines is read, the determination result is "YES" and the process proceeds to step SF7. In step SF7, the read start pointer is reset and this routine is completed.

On the other hand, when the reading of the OBJB code is not completed, the judgment result of the above step SF6 is "N".
O ”, the process proceeds to step SF8, and the OBJB code string forming a character string designated based on the value of the pointer register i and the current address (X, Y) is read. Next, in step SF9, the read OBJB code string is interpreted character by character, and it is determined whether the interpreted OBJB code is a "space". Here, if it is "space (blank)", the determination result is "YES", and the process proceeds to the next step SF10 to set a transparent character (transparent color designation).

On the other hand, when it is not "space", the result of the determination in step SF9 is "NO", and the process proceeds to step SF11 to set the object B character (character image) designated by the OBJB code. To do. Then, after this, the CPU 1 executes the step SF1.
The process proceeds to step 2, the interpreted OBJB code is stored in the object memory 52 inside the VDP 5, the pointer register i is incremented by 1 in the subsequent step SF13, and the process returns to step SF6.

As described above, in the character string changing process, 18 character strings, 6 characters from the storage area of the ROM 2 are set based on the cursor position scrolled according to the operation of the cross key 109.
The OBJB code for the line is read according to the value of the pointer register i, and when the read OBJB code is "space", a transparent character (transparent color designation)
Is set, and when it is not, the object B character (character image) designated by the OBJB code is set. In other words, all the characters to be changed in display are set in the object B image, the corresponding OBJB code may be specified when changing the display, and the transparent color may be specified when deleting the display. The screen display can be performed at a higher speed than the conventional one in which the display form and the display coordinate position are designated for each).

(D) Color block change processing (OBJB)
Operation of Routine Next, the operation of the color block change processing routine for changing the display color of the object OBJB that is the display change target will be described with reference to FIG. Since the object B image is assigned with a 1-bit color code per dot as described above, the color block number is changed and displayed as can be seen from the color lookup table CLT3 _OBJB shown in FIG. 15, for example. The color is "black"
And can be switched to "pink" alternately. When changing the color block of the object OBJB,
"Black" corresponds to the "normal color" described below, and "pink" corresponds to the "active color" described below.

Now, for example, it is assumed that the change of the character string (object OBJB) is completed by the above-mentioned character string change processing routine. Then, the CPU 1 changes the display color of the changed character string in step SE described above.
31 through the color block changing process (OB
JB) routine is executed and the process proceeds to step SG1. In step SG1, an object to be changed is first designated. Next, in step SG2, it is determined whether or not the display color assigned to the target object is a "normal color". Then, if it is "normal color", the determination result is "YES", the process proceeds to the next step SG3, and the color block number for assigning "active color" to the object is calculated.

On the other hand, when the display color assigned to the target object is the "active color",
The result of the determination made in step SG2 is “NO”, and CP
U1 advances the processing to step SG4, and calculates the color block number for assigning "normal color" to the object. After that, when the process proceeds to step SG5, the color block number in the target object OBJB code is set to the above step SG3 or step SG.
Rewrite to the color block number calculated in 4. As described above, in the color block changing process (OBJB), the color block number of the active color is assigned when the display is changed in the normal state, and the color block number of the normal color is assigned in the opposite case.

(E) Operation of Band Member Change Processing Routine When a band member change operation is performed on the band screen to replace one of the five portrait images of the musician displayed on the screen with another, the CPU
1 through the above-mentioned step SE7 (see FIG. 29).
The band member change processing routine shown in 2 is executed, and the process proceeds to step SH1. In step SH1, an object movement processing routine (described later) is executed to move and display the portrait image of the member at the designated position. And
In step SH2, the display color of the object OBJA corresponding to this moved and displayed portrait image is changed based on the operation of the object color change processing routine (described later).

(F) Operation of Object Moving Processing Routine When the above step SH1 is executed, the CPU 1 executes the processing shown in FIG.
The object movement processing routine shown in is executed and the processing proceeds to step SJ1. In step SJ1, it is determined whether or not an operation of displaying the selected member has been performed. Here, the operation of displaying the selected member means the character string CHR7 displayed at the bottom of the band screen shown in FIG.
It indicates an operation of moving the cursor to the position of "(MEMBER)", pressing the enter key 111 there to transition to the band member change mode, and then designating the "part" to be changed. When such an operation is performed, the determination result of step SJ1 is “YES”, and the process proceeds to the next step SJ2. On the other hand, if the operation of displaying the selected member is not performed, the process proceeds to step SJ4 described later.

In step SJ2, the display position coordinates (X, Y) of each object OBJA code forming the selection item display area is changed to move to the display area B outside the screen display range. The selection item display area mentioned here refers to a screen range that is a lower half of the portrait image in the band screen. Then, in the next step SJ3, the display position coordinates (X, Y) of the object OBJA code for the selected member are moved to the display area A side instead of the selection item display area. The selected member refers to a portrait image of a selection candidate that is pre-assigned to the “part” whose member is to be changed. That is, in the above steps SJ2 to SJ3, when the operation of displaying the selected member is performed, the selection item display area is moved to the display area B outside the screen display range, while the selection candidates arranged on the display area B side are moved. The portrait image of is moved to the display area A side instead of the selection item display area. As a result, the band member change screen shown in FIG. 19 is formed.

Next, when proceeding to step SJ4, the CPU 1
Determines whether or not an operation of changing the selected member, that is, an operation of displaying a portrait image as a new candidate has been performed. Then, when the operation of changing the selected member is performed, the determination result is “YES”, the process proceeds to the next step SJ5, and the display position coordinates (X, X, of the object OBJA code of the member selected by the change
Y) is moved to the display area A side to be displayed as a new candidate portrait image. Next, in step SJ6, in response to the display of the new candidate portrait image, the object OBJA of the member removed due to the change is displayed.
The display position coordinates (X, Y) of the code are moved to the display area B side to be hidden.

The operation of steps SJ5 and SJ6 is shown in FIG.
The band member change screen illustrated in FIG. 9 will be described as an example. First, it is assumed that portrait images of three persons who are candidates for selection are displayed on the lower half side of the screen. And in order to display a portrait image that is a new candidate from this state,
Perform the operation to change the selected member. Specifically, the right key or the left key of the cross key 109 arranged on the device panel surface is operated to replace the candidates. That is, when the right key is operated, the portrait image at the right end moves to the display area B side and is hidden, and accordingly, the portrait images at the center and left ends are sequentially shifted to the right side. As a result, a vacancy is formed at the left end, and a portrait image of a new candidate is moved and displayed at this position from the display area B side. When the left key is operated, contrary to the above, the portrait images at the center and the right end are respectively shifted to the left, and a new candidate is displayed at the right end position. Therefore, if one of the left and right keys is continuously operated, the candidate portrait image is sequentially updated through the left shift cycle or the right shift cycle.

When the selected member has been changed as described above, the CPU 1 proceeds to step SJ7 shown in FIG. 34 and determines whether or not an operation for member determination has been performed. Here, when the enter key 111 is pressed to determine a predetermined member (portrait image), the determination result is “YES”, and the process proceeds to the next step SJ8. In step SJ8, the display position coordinates (X, Y) of the object OBJA code of the member currently determined,
The display position coordinates (X, Y) of the object OBJA code of the member to be changed are exchanged with each other. As a result, the portrait image of the currently determined member is fixed to the display area A side.

Next, in step SJ9, it is determined whether or not the escape key 110 for returning the display state to the original state is operated. When the key 110 is not operated, the determination result is "NO", and this routine is once executed. Complete. On the other hand, when the escape key 110 is operated to restore the display state, the determination result is “YES”, and the process proceeds to the next step SJ10. In step SJ10, the display position coordinates (X, Y) of each object OBJA code of the portrait image displayed as the selection candidate.
Is moved to a display area B outside the screen display range. Then, in the next step SJ11, the display position coordinates (X, Y) of each object OBJA code of the selection item display area saved in the display area B outside the screen display range are set to the source of the display area A. Change to display in position. That is, in steps SJ10 to SJ11, when the escape key operation to restore the display state is performed, the portrait image displayed as the selection candidate is returned to the display area B outside the screen display range, while the display area B is displayed.
Each object in the selection item display area saved to the side is moved to the original display area A side and set to the display state.
As a result, the band member change screen is switched to the band screen.

(G) Operation of Object Color Change Processing Routine When the object movement processing routine for changing the display position of the portrait image according to the change of the band member is performed in this way, the CPU 1 executes the above-mentioned step SH2 (FIG. 32).
35), the object color change processing routine shown in FIG. 35 is executed, and the process proceeds to step SK1. In step SK1, an object whose display color is to be changed is obtained in cooperation with the processing of the object moving processing routine described above. Then, after step SK2, the color block number in the object code is rewritten according to the display color of the object whose color is to be changed. The processing will be described below according to the contents of color change.

When changing to a normal color When the band member changing operation is completed and the screen returns to the band screen, the object OBJA to be processed is changed to a normal color indicating a steady state. In this case, the determination result of step SK2 is “YES”, and step SK
In step 3, the color block number having the normal color of the target object OBJA is calculated. Then, in the next step SK4, the target object OB
The color block number in the JA code is rewritten to the color block number of normal color.

When changing to a select color When selecting a desired member when changing a band member,
The object OBJA to be processed is changed to a select color representing the selected state. In this case, the determination result of step SK5 is “YES”, and the process proceeds to step SK6,
The color block number having the selected color of the target object OBJA is calculated. And the next step S
In K7, the color block number in the target object OBJA code is rewritten to the color block number of the selected color.

When changing to an active color When deciding a desired member when changing a band member,
The object OBJA to be processed is color-changed to an active color representing the determined state. In this case, the determination result of step SK8 shown in FIG. 36 is “YES”, and the process proceeds to step SK9 to calculate the color block number having the active color of the target object OBJA. Then, in the next step SK7, the color block number in the target object OBJA code is rewritten to the color block number of the active color.

As described above, in the object color changing processing routine, the object whose display color is to be changed is obtained in cooperation with the processing of the object moving processing routine described above,
Corresponding OB according to the transition state of the obtained object
The color block number in the JA code is rewritten to indicate one of "normal color", "select color" and "active color". Therefore, for example, as the object whose color is to be changed, the display color of the frame portion of the portrait image or the part name portion arranged below the portrait image is changed according to the transition state. This allows the so-called GUI even if the device does not have a mouse.
The environment can be realized and the operability can be improved.

(H) Operation of Genre Select Screen Processing Routine When the band screen processing routine is completed as described above, the CPU 1 executes the above-mentioned step SC4 (see FIG. 27).
37, the genre select screen processing routine shown in FIG. 37 is executed, and the process proceeds to step SL1. In step SL1, it is determined whether or not the current mode is under the genre select mode for selecting a performance genre. If not, the result of the determination here is "NO", and this routine is completed. On the other hand, if it is in the genre select mode, the determination result is “YES”, and the process proceeds to the next step SL2. In step SL2,
It is determined whether the generated event is an event that requires image change.

The event requiring an image change on the genre select screen is, for example, an operation of selecting a character string in the window WIN on the genre select screen (see FIG. 20) according to the up / down key operation of the cross key 109, Refers to the operation to change the character string by newly inputting characters in the selected character string portion. When the above selection operation or character string changing operation is performed, step SL2
The result of the determination is "YES", and the process proceeds to step SL3. If the operation does not require image change, the result of the determination here is "NO", and this routine is completed.

When an event requiring an image change is generated and the process proceeds to step SL3, CPU 1 determines whether or not the operation is a character string change. Here, if the character string in the window WIN is simply selected in response to the up / down key operation of the cross key 109, the determination result is "NO", and the process proceeds to step SL4. In step SL4, a color block changing process (OBJB) routine (see FIG. 31) for changing the display color of the character (object OBJB) at the cursor position that moves in the window WIN according to the operation of the cross key 109 is executed.

That is, as described above, in the color block change processing (OBJB) routine, when the cursor is positioned at the "character" portion in the normal state (black) and the display change is designated, that "character" is activated. Rewrite the color block number of the corresponding object code to display in color (pink). Conversely, when the display change from active state to normal state is specified,
Assign normal color block numbers.

On the other hand, when the character string in the window WIN is changed by inputting a new character in the character string selected according to the up / down key operation of the cross key 109, the judgment in step SL3 is made. The result is "YES" and C
PU1 advances the process to step SL5. Step SL
In 5, the above-mentioned character string change processing routine (see FIG. 30) is executed. That is, when the character string is changed on the genre selection screen, the ROM is set based on the cursor position scrolled according to the operation of the cross key 109.
The OBJB code of 18 character strings and 8 lines is read from the storage area of 2 according to the value of the pointer register i, and when the read OBJB code is "space (blank)", a transparent character (transparent color designation) is set. If not, the object B character (character image) designated by the OBJB code is set, and this routine is completed.

(I) Operation of Total Control Screen Processing Routine Next, the operation of the total control screen processing routine will be described with reference to FIGS. 38 to 40. When the above-mentioned genre selection screen processing routine is completed, the CPU 1
Executes the total control screen processing routine shown in FIG. 38 through step SC5 (see FIG. 27) and advances the processing to step SM1. In step SM1, it is determined whether or not the current mode is the total control mode for setting the operation mode of the entire apparatus. If not, the determination result is "NO", and this routine is completed.

On the other hand, if it is under the total control mode, the judgment result is "YES", and the next step SM
Processing proceeds to 2. In step SM2, it is determined whether the event that has occurred is an event that changes the image in the total control screen. Here, the event for changing the image is, for example, the “button” displayed on the total control screen (see FIG. 23) and the cross key 1
It refers to an operation selected according to the operation of 09 or a pressing operation of the enter key 111 performed when setting the operation mode associated with the selected “button”. And
When the cross key 109 or the enter key 111 is operated, the determination result of step SM2 becomes “YES”,
The process proceeds to step SM3. If the operation does not require image change, the result of the determination here is "NO", and this routine is completed.

When the cross key 109 or the enter key 111 is operated and an event that requires an image change occurs, the CPU 1 advances the processing to step SM3, and the operation changes the display state of the "button". Determine whether or not. Here, when it is an event in which the display state of the "button" does not change, the determination result becomes "NO", the process proceeds to the next step SM4, and other changes such as initialization for initializing the setting of the entire device are performed. The process is executed to complete this routine. On the other hand, when an event that changes the display state of the "button" occurs, the determination result of step SM3 is "YES", and CP
U1 advances the processing to step SM5, executes the button color block changing processing routine described later, and displays the display state of the corresponding button in the "concave-like normal state", "selection state" and "convex state" shown in FIG. The display color of the object forming the "button" is changed so as to be in one of the "active states".

(J) Operation of Button Color Block Change Processing Routine As described above, when an event for changing the display state of the "button" occurs, the CPU 1 executes the button color block change processing shown in FIG. 39 through step SM5. Run the routine. In this routine, for simplification of description, a color block change related to the "BeepOn button" among various buttons will be described as an example.
When this routine is executed, the CPU 1 executes step SN1.
Then, the processing is advanced to and it is determined whether or not the processing target is the "BeepOn button". If it is other than the "BeepOn button", the determination result is "NO", and the process proceeds to step SN2. Then, in step SN2, a color block changing process for other buttons than the "BeepOn button" is performed. On the other hand, when the processing target is the "BeepOn button", the determination result of step SN1 is "YES".
Then, a BeepOn button color block change processing routine, which will be described later, is executed, and the display color of the "button" forming object is changed to change the button display mode according to the operation mode performed for the button.

(K) Operation of the DeepOn button color block change processing routine When this routine is executed, the CPU 1 advances the processing to step SP1 shown in FIG. 40, and displays the target display color in accordance with the operation mode performed for the DeepOn button. To set.
The operation modes will be described below. When button is selected Operate cross key 109 to turn ON button or OFF
The button is selected by positioning the cursor on one of the buttons. In this case, the target display color becomes the "selected color" indicating the selected state, and the process proceeds to step SP2. In step SP2, the color block number corresponding to this "selected color" is calculated and stored in the register destCblock.
Store at. In the case of the color lookup table CLT4 _OBJA shown in FIG. 16, since the “select color” is color block # 8, “8” is set in the register destCblock.

At the time of button decision (setting) The button is decided by turning on the enter key 111 in the above-mentioned button selection state. In this case, the target display color becomes the "active color" indicating the decision (setting) state, and the step In step SP3 where the process proceeds to SP3, the color block number corresponding to this "active color" is calculated and stored in the register destCblock. FIG.
In the case of the color lookup table CLT4 _OBJA shown in (1), since "active color" is color block # 7, "7" is set in the register destCblock.

When canceling the setting When the enter key 111 is turned on when deciding the button, the setting of the paired button having an exclusive relationship with the operated button is canceled and a "normal color" indicating an unset state is obtained, The process proceeds to step SP4. In step SP4, the color block number corresponding to this "normal color" is calculated and stored in the register destCblock. Color lookup table CLT4 shown in FIG.
_In the case of _OBJA , since "normal color" is color block # 1, "1" is set in the register destCblock.

When the color block number corresponding to the display mode is set in the register destCblock in this way, the CPU 1
Advances the processing to step SP5. In step SP5, the objects OBJA-A to OBJA- that form the change target button (ON button or OFF button)
An object whose color is to be changed is extracted from C (see FIG. 24B). Next, in step SP6, the color block value assigned to the upper 4 bits of the OBJA code corresponding to the extracted object is set in the register destCb.
Rewrite to the color block number stored in lock. As a result, the display mode is changed so that the button looks concave when the color is normal, and convex when the color is active, and the display mode is such that it shows an intermediate state between the two when the color is selected. Is changed.

(L) Operation of Band Save Screen Processing Routine When the above total control screen processing routine is completed, the CPU 1 executes the band save screen processing routine shown in FIG. 41 through step SC6 (see FIG. 27) and then executes the step. The process proceeds to SQ1. In step SQ1, it is determined whether or not the current mode is the band save mode for band registration. If not, the result of the determination is "NO", and this routine is completed.

On the other hand, if it is in the band save mode, the determination result is "YES", and the process proceeds to the next step SQ2. In step SQ2, it is determined whether the event that occurred is an event that changes the image in the band save screen. The event for changing the image is, for example, an operation of selecting a character string in the window WIN displayed on the band save screen (see FIG. 22) according to the operation of the cross key 109, or a selected character string. Refers to the character string modification operation to be rewritten. Then, when these operations are performed, the determination result of step SQ2 becomes “YES”, the process proceeds to step SQ3, and when any other operation is performed, the determination result is that the operation does not require image change. This becomes "NO", and this routine is completed.

Now, it is assumed that the cross key 109 or the enter key 111 is operated and an event requiring image change occurs. Then, the CPU 1 advances the processing to step SQ3, and determines whether or not the operation is "select character string". Here, when "character string selection" is performed by operating the up and down keys of the cross key 109, the determination result is "YES", and the process proceeds to step SQ4.
In step SQ4, a color block change processing (OBJA) routine, which will be described later, is executed to change the display color of the object OBJA placed at the same position as the selected character string (object OBJB) to "select color" to change the selected state. This routine is once completed.

On the other hand, when an operation other than "select character string" is performed, the result of the determination in step SQ3 is "NO", and the process proceeds to step SQ5. Step SQ5
Then, it is determined whether or not an operation of rewriting the selected character string is performed, and if such an operation is not performed, the determination result is “NO”, the process proceeds to step SQ6, and the process corresponding to the operation is executed. To do. On the other hand, when the operation of rewriting the selected character string is performed, the determination result of step SQ5 becomes “YES”, and step SQ
Processing proceeds to 7.

In step SQ7, the CPU 1 executes the above-mentioned character string changing processing routine (see FIG. 30). In this character string change processing routine, the cross key 109

The BJB code is read according to the value of the pointer register i, and the read OBJB code is "space".
When is, set a transparent character (specify transparent color),
Otherwise, the object B character (character image) designated by the OBJB code is set. And
In step SQ8, the CPU 1 executes the above-described color block change processing (OBJB) routine (see FIG. 31) to change the active color to the active color when the target object is the normal color, and to the normal color when the target object is the reverse color. Change the color.

(M) Color block change processing (OBJA)

PU1 advances the process to step SR1. First, in step SR1, a target object that matches the cursor position that moves according to the operation of the cross key 109 is obtained. After step SR2, the color block number in the object code is rewritten according to the display color of the object whose color is to be changed. The processing will be described below according to the contents of color change.

When changing to a normal color The object OBJA deselected from the selection target by the operation of the cross key 109 is changed to a normal color indicating a steady state. In this case, the determination result of step SR2 is "YE
S ”, the process proceeds to step SR3, and the color block number having the normal color of the target object OBJA is calculated. Then, in the next step SR4, the color block number in the target object OBJA code is rewritten to the normal color block number.

When changing to the select color The object OBJA selected by the operation of the cross key 109 is changed to the select color representing the selected state. In this case, the determination result of step SR5 is "YE
S ”, the process proceeds to step SR6, and the color block number having the selected color of the target object OBJA is calculated. Then, in the next step SR7, the color block number in the target object OBJA code is rewritten to the color block number of the selected color.

In this way, the color block change process (O

As described above, in this embodiment, the characters that are fixedly displayed on the screen, such as the screen title, are formed by the object A image, and the characters that are changed in display are displayed on the object A image. Object B for the maximum number of characters that can be displayed in advance in the display area (display line)
When an image is placed and the character is rewritten, only the character name (character type) in the OBJB code corresponding to the display position is changed, and when the character is erased, the color block in the OBJB code is transparently specified. To hide it. Therefore, as in the conventional image control device, both the type of display and the display coordinates of the characters to be displayed and changed on the screen and the fixed display such as the screen title can be managed individually, or When deleting, the process of moving the display position in the corresponding object code to the outside of the screen display area becomes unnecessary. Therefore, it is possible to improve the processing speed without using a high-speed CPU, in other words, it is possible to improve the processing speed without inviting an increase in cost.

Further, in the above-mentioned embodiment, even if the pointing device such as the mouse is not provided, the object A image whose display color is to be changed according to the operation of the cross key 109 or the enter 111 is designated, and the object A image is designated. Corresponding OB
Since the color block number in the JA code is rewritten to indicate one of "normal color", "select color" and "active color", the image display mode can be changed according to the contents of the key operation. A GUI environment can be realized, and as a result, operability is improved by preventing erroneous operations. As a point similar to this, in the above-described embodiment, the "button" displayed on the screen is replaced by the object OBJ.
A-A to OBJA-C (see FIG. 24B),
The display colors of these objects OBJA-A to OBJA-C are changed according to the content of the operation mode for changing the image, and the state of the corresponding "button" (normal state, selected state, and active state) is displayed, so that the visibility is improved. Excellent G
A UI environment is achieved.

Further, in the above-described embodiment, the inversion flag X is provided in the OBJA code of the object A image fixedly displayed on the screen, and the object A image data is stored in the line buffer according to the value of the flag X. Since it is possible to specify whether to write the data in the address order or in the reverse order when writing, one image data is displayed as a normal image written in the address order or written in the reverse order. With, it becomes possible to display a reverse image in which the left and right of the image are reversed. That is, it becomes possible to form two images of one image data that is normally displayed and one that is displayed in reverse, so that the number of types of images that can be displayed is increased and the image data is displayed for a system with a small memory capacity. It can be used efficiently.

In this embodiment, the case where the image control device according to the present invention is applied to the musical tone control device connected to the display has been mentioned, but needless to say, the gist of the present invention is not limited to this. The present invention is applicable not only to information devices such as personal computers and word processors, but also to mobile terminal devices (pagers, PHSs, etc.) and video game devices. The point is that any device that realizes a user interface using images can apply the gist of the present invention, and by doing so, it is possible to increase the cost of the product while realizing an operating environment with excellent visibility and preventing erroneous operations. The remarkable effect is that the processing speed of display control is improved without being invited.

According to the present invention, a display area of a change image whose display mode can be changed is defined in advance on the screen, and the image arrangement means arranges as many change images as can be displayed in this display area. In other words, if any one of the changed images arranged in the display area is changed by the changing unit and the display mode is changed, the changed image is updated according to the changed display mode, and this is changed by the display control unit. The screen is displayed according to the arrangement in the display area. That is, since only the image whose display mode is changed is the update target, it is possible to improve the processing speed without using a high-speed CPU.
In other words, the processing speed can be improved without inviting an increase in cost.
