In addition, since the commercially available animation generation software 103 is used, there is a merit of data compatibility, but because of the marketability, the animation creation software 103 is intended to satisfy various demands. Reference numeral 105 does not mean that the image reproduction is efficient. Further, driving software 106 for driving the animation data 105 is required, and the distribution file 107 becomes large. As a result, distribution and transmission are difficult.

An image display device used in a conventional image display system is a play personal computer 108 or the like. When an animation is reproduced by the play personal computer 108, the driving software 106 is operated using the CPU of the play personal computer 108 or the basic OS 102, that is, since the software (hereinafter, referred to as software) is used, the drawing speed is low. Also, functions such as data compression, enlargement, and reduction are not sufficient.

In addition, in the invention according to claim 5, in the image display device according to claim 3 or 4, in the active mode, one scenario, that is, drawing executed linearly according to a program stored in image data. Only the work is handled, and in the passive mode, two or more scenarios are handled. Thus, when the number of scenarios to be handled becomes two or more, image drawing is performed in the passive mode involving the CPU memory. For this reason, except for a complicated scenario having a plurality of scenarios, processing can be performed by a dedicated graphic LSI, and image reproduction can be performed efficiently and at high speed.

[0022]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. Note that this embodiment is a system for playing back an animation, and specifically, an animation is displayed on an image display portion of a guidance display placed on a street corner.

The image display system according to this embodiment is the same as the conventional one shown in FIG. 23 in that an animation image is created by the personal computer 1 for creating animation.
The output image data is different. That is, as shown in FIG. 1, a personal computer 1 for animation creation has a basic OS 2 and software 3 for animation scenario creation running on the basic OS 2 installed. Then, the animation data 5 is created using the animation scenario creation software 3. The animation data 5 is usually created using the base picture 4 as each sprite created by the animation creator. Then, the animation data 5 is output from the animation creation personal computer 1, the animation data 5 is put into the conversion software 6 operating on the animation creation personal computer 1, and the dedicated animation data 7 serving as image data is output. The exclusive animation data 7 is converted to a ROM and stored in a ROM 8, which is then distributed to a downsized dedicated player 9. The distribution here is
Although the processing is performed in the ROM 8, the dedicated animation data 7 may be transmitted to the dedicated player 9 via wireless or wired communication.

The distributed ROM 8 is attached to a dedicated player 9 serving as an image display device. Dedicated player 9
As shown in FIG. 2, a display unit 10 composed of an LCD (liquid crystal), a CPU memory (= central processing unit) 11, a dedicated graphic LSI 12, a program ROM 13,
A data receiving circuit 15 for receiving an instruction from the external information source 14 and transmitting it to the CPU memory 11;
(VRAM) 16 connected to the external device 2 and a sound circuit 18 for supplying sound to an external amplifier or speaker 17
And a display unit LSI 19 for driving and controlling the display unit 10.

The external information source 14 is a dedicated player 9
, And controls the display content of the dedicated player 9 on a large scale. That is, the external information source 14
Can change the flow of the animation (= change the scenario) and give an instruction to display a specific sprite at a specific position. In the program ROM 13, the CPU memory 11 takes in specific data from the dedicated animation data 7 and receives a program for controlling display on a frame-by-frame basis and a command from the external information source 14, and displays the program on a frame-by-frame basis. A program for performing a process of switching a flow or displaying a specified specific sprite at a specified specific position is stored.

In this embodiment, the ROM 8 stores
It is 2 Mbytes and has a capacity equivalent to several tens of seconds on a television screen. The CPU memory 11 is an 8-bit CPU and has a 512-byte work memory therein.
It has K bits. In addition, as these members,
The values are not limited to those shown here, and those having other values can be appropriately adopted.

Here, the dedicated graphic LSI 12
While the sequence of each screen is controlled by the CPU memory 11, the display of a series of sprites in each screen is performed by checking data in the ROM 8 and performing a series of movements of the sprite based on the data. Control. The display section 10 can be of various sizes such as 3.3 inches, 4 inches, 5 inches, and 5.6 inches. If necessary, a display body other than a liquid crystal, such as a cathode ray tube type, can be employed. Further, the VRAM 16 can take in two screens, and has a 2 M bit for a 5 inch display section and a 1 M bit for a 4 inch or 3.3 inch screen. The reason why two screens are used is that one screen is used for display and another screen is used.
This is because the screen was used for writing. This two-screen method eliminates flickering during writing and improves image quality. The sound circuit 18 is an 8-bit, 8KH
z, one channel, but other values can be used as appropriate.

The structure of the dedicated graphic LSI 12 is as shown in FIG. That is, the small processor unit 12 having the function of a programmable downloader
a, a register section 12c comprising about 60 registers and a palette RAM section 1 comprising 128 bytes of RAM
2d having a video display processor unit 12b. And this dedicated graphic LSI
12 is a ROM based on the execution instruction of the CPU memory 11
8 is read.

On the other hand, the data structure of the ROM 8 is shown in FIG.
As shown in (A), an external processor control data section 8a containing scenario data interpreted and executed by the CPU memory 11, and a program such as an in-frame sprite display program interpreted and executed by the small processor section 12a in the dedicated graphic LSI 12. Processor control program section 8b containing data and a special graphic L
It is mainly divided into an image data section 8c containing compressed image data for accessing and downloading data by the video display processor section 12b in the SI 12. The internal processor control program unit 8b includes an MC (microcontroller) program 8d for operating the small processor unit 12a and a register unit 12c.
And register data 8e serving as data relating to the palette RAM section 12d. Further, the image data section 8c contains multi-color compressed image data 8f which is compressed data of a multi-color image to be described later and natural image compressed image data 8g which is compressed data of a natural image.

As shown in FIG. 4B, data for controlling each frame 20 in the time axis direction is written in the external processor control data section 8a. In addition, each frame 20 is switched at a speed of appearing 25 frames in one second. On the other hand, the internal processor control program unit 8
In b, an MC program 8d for controlling a display position of a sprite (details will be described later) in one frame 20 is written.

Here, the operation of the dedicated graphic LSI 12 will be briefly described with reference to FIG. When the CPU memory 11 instructs the dedicated graphic LSI 12 to execute the ROM 8 at, for example, the address [XXXXH], the small processor unit 12a executes the data from the ROM 8 at the address [XXXXH]. In the ROM 8, [XXXX
H], the MC program 8d, the register data 8e, and the compressed image data in the image data section 8c are written in order from the address, and are sequentially executed.

Specifically, as shown in FIG. 3B, for example, when the CPU memory 11 instructs execution from address 100, the small processor unit 12a
Execute data from address. For example, if the sprite is the characters "A", "B", and "C", first,
An "A" MC program at address 100 for displaying "A" is executed. This execution is performed by setting various parameters for displaying “A” in the register unit 12c,
This is performed by downloading the compressed image data “A” to the RAM 16. Similarly, the image data of the characters “B” and “C” are stored in the register 12 c and the VRAM 1.
6 is downloaded. When the above relationship is viewed mainly with the dedicated animation data 7, the relationship is as shown in FIG. That is, the dedicated animation data 7 in the ROM 8 controls the CPU firmware 31 including the CPU memory 11 and the program ROM 13 and the hardware specification 32 of the dedicated graphic LSI 12. As a result, the dedicated player 9 used in the image display system realizes various display functions in cooperation with the CPU firmware 31, the hardware specification 32 of the dedicated graphic LSI 12, and the dedicated animation data 7. I have.

Next, the mechanism of the display function will be described. In the future, the term "sprite"
Let's refer to the components of the image in one frame 20 of the animation. For example, characters such as [A], [B], and [C], pictures such as apples and persimmons, and geometric figures such as triangles and squares are equivalent. The “sprite screen” refers to a screen that displays such a “sprite”.

In general, each frame 20 which is a screen in an animation is composed of a plurality of sprite screens. In other words, it is composed of a multi-color sprite composed of a multi-color image and a natural image sprite that is a natural image. These two types of sprites
Small processor unit 12 in dedicated graphic LSI 12
a is independently moved and rendered (active mode described later), or the CPU memory 11 and the small processor unit 12a are rendered in cooperation (passive mode described later). Note that the multi-color sprite also includes a specific image sprite that the CPU memory 11 draws at a specific position according to an instruction from the external information source 14. The animation screen of this embodiment has, for example, a configuration having a plurality of multi-color sprites and a natural image sprite, as shown in FIG. At other times, the above-described specific image sprite may be provided. When these sprites overlap, the sprite that comes to the front is displayed with priority. However, since each sprite except the natural image sprite has a palette color that is “transparent” in the palette described later, the color of the screen on the rear side can be displayed using the “transparency”. ing.

Here, the multi-color sprites are both for animation and are mainly used for animation by characters. Both multi-color sprites have a smaller number of colors than the natural image sprite, but the image data is correspondingly small, so that they are suitable for a screen displaying a large number of characters. Moreover, both multi-color sprites are 15
Although any of 30, 30, 45, and 60 colors can be selected and used, this embodiment employs 15 colors.

On the other hand, the specific image sprite is rendered by the CPU memory 11 and is directly controlled by the external information source 14, but the nature is a multi-color sprite. The display position of this specific image sprite is set at a fixed location such as the center or edge of the screen, unlike other sprites, but it can be moved, superimposed, enlarged, and reduced like other multicolor sprites. And so on.

As will be described later, the natural image sprite has a large number of colors and can be displayed in high detail. Therefore, it is mainly used for backgrounds using natural colors.

Here, the multicolor sprite has a palette table that can provide 15 of 32K colors. And, up to 60 colors can be developed on these three screens. The 32K color is obtained by setting the values of the three primary colors of red (R), green (G), and blue (B) to 5
This is because it is represented by bits. In other words, the total is 15 bits, which is a 32K color. Each screen M
1, M2, and SC each have a palette table that specifies 15 of the 32K colors. This is because the hardware used in this embodiment can handle only 4-bit sprite screens,
A maximum of 16 colors are available, one of which is transparent.

On the other hand, the natural image sprite has a direct color system capable of simultaneously producing 256K colors. This is because R, G, and B are represented by a total of 18 bits of 6 bits each, and the values are directly displayed.

Here, the reason why a plurality of multi-color sprites are prepared is, for example, that an image of a guide in a guide display is
This is to superimpose the image on the screen of the multi-color image as the background. The natural image sprite is for representing, for example, a beautiful woman or delicious food. Further, the specific image sprite, for example, is used to display time, display an image of a throttle machine, and add a function like a throttle machine when using a guidance display. When such a specific image sprite is used, the use value of the guide display device is increased, and the use of the guide display device can be performed like a game.

As shown in FIGS. 7 and 8, the screen having each sprite is selected from a combination of the three modes and the priority designation of the natural image sprite. 7A is a specific image top mode in which a specific image sprite is drawn last, FIG. 7B is a specific image second mode in which a multicolor sprite is drawn after drawing the specific image sprite, and FIG. C) is a specific image bottom mode in which two multi-color sprites are drawn after the specific image sprite is drawn. on the other hand,
FIG. 8 shows a case where, for example, in the specific image top mode, the drawing priority order of the natural image sprite which determines at which point the natural image sprite is drawn is specified. In this manner, three modes and four different drawing orders can be specified, and a total of 12 drawing orders can be performed.

Each sprite can display an arbitrary number of sprites, for example, an animated character. That is, in this embodiment, the number of sprites is not limited by hardware, but is limited by the time required for sprite drawing processing. For example, when the drawing rate (= frame rate) of each frame is 25 Hz, 16 inches of 4 inch full size
Approximately 5.7 color screens can be drawn, and about 24 sprites can be drawn if the sprite has a size of 1/4. By the way, if it is a natural image sprite, about 3.8 sheets can be drawn.

As for the drawing priority of each sprite, an arbitrary priority can be specified for each sprite.
That is, the order of overwriting can be freely changed. In the conventional case, there are many situations in which the number of sprites (two on a screen) and the priority of each of the two are determined. For example, if there is a sprite A and a sprite B in one screen, the sprite A is stored in one specific register and the sprite B is stored in another specific register. Then, the display of the sprites A and B is switched by switching the register. On the other hand, in this embodiment, the register of each sprite is not specified, and the sprite is displayed by changing the order of writing. ing. That is, the sprite written earlier is erased by the sprite written later. As described above, in the present invention, there is no limitation on the number of sprites or the display order,
It is easy to handle and the register is light,
That is, it can be small.

The size of each sprite, for example, an animated character, is 1 in the horizontal direction in a multi-color sprite.
1,008 pixels, and the vertical direction is 1 to 255 pixels. On the other hand, in the natural image sprite, the horizontal direction is 1 to 10
08 dots and 1 to 255 dots in the vertical direction. This is because, in this embodiment, a liquid crystal screen of a maximum of 5 inches, that is, a screen of 960 dots × 240 dots is designated. The reason why the natural image sprite is set in dot units is to improve the image quality. On the other hand, the multicolor sprite has a palette of representative colors with one RGB, and the unit is a pixel, that is, a representative color unit.

In the multi-color sprite, the display position of each sprite can be specified in units of one pixel consisting of specific values of RGB, and the natural image sprite is in units of three dots in both the horizontal and vertical directions. . This 3
As shown in FIG. 9A, the designation of the dot unit represents each of RGB with each of the three dots, the next line is shifted by one, and repeated in the order of GBR, and the third line is repeated with BRG. Has become. Such a display method is called a mosaic type, and is adopted when the resolution is low. If not a mosaic type, see FIG. 9 (B)
It is conceivable to adopt a unit of 3 dots in the horizontal direction and 1 dot in the vertical direction as shown in FIG.

The expansion and reduction of each sprite can be performed independently in the vertical and horizontal directions.
Note that the ratio of enlargement and reduction can be continuous in both the horizontal and vertical directions. Is to do.

The size of the enlargement and reduction in the horizontal direction is 1 to 255 pixels when the original horizontal width is 1 to 16 pixels, and 17 to 3 pixels.
In the case of two pixels, 2 × n (n: 1 to 255) pixels and 3 pixels
In the case of 3 to 48 pixels, it is 3 × n (n: 1 to 255). In this manner, enlargement and reduction are performed in units of 16 pixels. For example, when the width of the original pixel is 160 pixels, it is 10 × n (n: 1 to 255, but does not exceed 1,008 pixels). This is a small processor unit 12a
However, this is because 16 pixels are processed in one unit.

The exclusive animation data 7 of this system is created in the order shown in FIG. The specific image sprite is created from the specific image data serving as the original data 21 using the animation creating software 3 that can configure a commercially available scenario or the like. The original data 21
Is often created by other image creation software 22. This original data 21 is processed to produce specific image data 23
Create Similarly, related display data 24 for displaying a specific image is created. The specific image data 23 and the related display data 24 are stored in the conversion software 6.

On the other hand, in the same manner for multicolor sprites and natural image sprites, original data 25 is created by other image creating software 22 and the sprite image data to be the original data 25 is converted to animation creating software 3.
To create the animation data 26. This is similarly input into the conversion software 6 and processed together with the previous data 23 and 24 to create dedicated animation data 7. The exclusive animation data 7 is stored in a character generator ROM.
Also called data. This exclusive animation data 7 is stored in ROM
To obtain a ROM 8.

The conversion software 6 takes in the specific image data 23, the related display data 24, and the animation data 26. Then, the conversion software 6 determines a combination of animation sequences in which each sprite is displayed (animation framing processing), adjusts and assigns an animation palette determined in the animation framing processing, and specifies various characteristics related to a specific image. Create data. In this data creation processing, when data is input based on a predetermined instruction in the animation creation software 3 and the data is processed by the conversion software 6, the creation processing can be automatically performed.

The conversion software 6 automatically performs the following processing to generate the dedicated animation data 7. That is, the video display processor unit 12b in the dedicated graphic LSI 12 takes in,
Generation of compressed image data for image data section 8c to be processed, encoding of sound data, CPU memory 11
Generates data for the external processor control data section 8a to be fetched and processed by a program stored in the program ROM 13;
The small processor unit 12a in the CPU 2 performs processing such as generation of a program for the internal processor control program unit 8b to be fetched and processed, and memory arrangement in the ROM 8. In this embodiment, the sound data is not encoded, but the conversion software 6 can generate the data. As described above, the conversion software 6 converts the data input to the animation creation software 3 into dedicated animation data 7 by rearranging, expressing, replacing, and compressing. Here, the term "re-expression" refers to changing the format or value of the data as it is without changing the content. Is achieved.

The external processor control data section 8
The data for a is stored in the CPU memory 11 or the program ROM.
Numeral 13 is data that operates by looking at this data, and is a kind of control data. The program and data for the internal processor control program section 8b are data for controlling the movement of a series of sprites for one screen.
The SI12 comes to see and operates the sprite based on the result. As described above, in this embodiment, the CPU memory 11 stores the dedicated graphic L
An instruction is issued to the SI 12 saying, "Look at a certain address in the ROM 8 and work in accordance with the instruction of that part." Based on the instruction, the dedicated graphic LSI 12 looks at the ROM 8 and
Processing is executed according to the address portion in the ROM 8.

The animation data 26 is shown in FIG.
Movement of sprite, appearance and disappearance of sprite, enlargement and reduction of sprite, palette data (= color) as shown in
, And a description along the time of the context of a plurality of sprites. In addition, when the last frame is displayed for each screen, the animation data 26 can also instruct whether to return to the beginning, keep displaying the last frame, or stop displaying the animation screen. It has become.

More specifically, each sprite is stored in a ROM.
8, that is, according to an automatic execution procedure called “scenario” in the animation data 26. In other words, it operates according to the scenario in the external processor control data section 8a of the ROM 8. This scenario proceeds in units of 1/25 seconds in this embodiment. The superimposition scenario is also included in the animation data 26.

That is, each sprite sequence is a scenario, and these scenarios are combined with the scenarios relating to the drawing priority of each sprite shown in FIGS. 7 and 8 to complete one animation.
On the other hand, when this relationship is viewed from the frame 20, each moment of each scenario corresponds to the frame 20, and a set of sprite scenarios corresponds to the time control of the frame 20. Note that the scenario has an interrupt scenario function, and after changing the scenario, it is possible to return to the place where the original scenario was interrupted. In a specific display example, this is equivalent to a case in which a display such as a pigeon indicating the time at noon or a train display 10 minutes before departure is displayed on the guidance display, and then the display returns to the original display. I do.

Further, each animation screen, that is, each frame 20 can be displayed at a predetermined moving speed, and an interruption animation can be applied to each animation screen. In addition, each animation screen contains an arbitrary number of sprites of any size,
It can be displayed at any position and with any display priority.

In addition, blending display of each multi-color sprite (including a specific image sprite) and a natural image sprite can be performed. Here, the blending process refers to a process in which a natural image sprite and another sprite are mixed and displayed, and look like a translucent picture. This is because sprites that were previously written are normally lost due to sprites that are normally overwritten, but in this blending process, so to speak, they are in a mixed state. In addition, this blending process can change the mixing ratio.For example, by gradually changing the mixing ratio, it is possible to bring out the effect of raising the bower or to give the effect of disappearing with Sue. I can do it. Since this blending process is turned on and off for each sprite, when a sprite is turned on, the sprite becomes translucent to the natural image sprite, that is, the sprite is mixed. Then, the degree of translucency (= blend coefficient) can be specified for each sprite, and the value can be specified by 14 levels of blend coefficients. These 14 steps are 4
Since two of the sixteen bits are assigned to the switch function, fourteen are used. Note that the blend coefficient stage is preferably in a range of 10 to 32 stages because a liquid crystal that does not easily produce fineness is employed as the display unit 10.

The image compression of each sprite is as described above, and has the following configuration. First, each sprite is divided into compression units of 16 pixels horizontally and arbitrary pixels vertically, and compressed. This is to reduce the number of hardware gates. Note that the image data may be divided into compression units of 16 pixels each in the horizontal and vertical directions and compressed. The division into these compression units is performed by the conversion software 6.

The compression of each multicolor sprite is a two-dimensional lossless compression of a parallel arithmetic compression system. On the other hand, the natural image sprite is irreversible compression that returns to almost original data when decoded. This is because the natural image sprite has a large number of colors, so that even if the reproducibility of a certain color is deteriorated, the effect is not so large and the compression rate is emphasized.

Next, the cooperative operation among the CPU memory 11, the dedicated graphic LSI 12, and the program ROM 13 will be described.

The cooperative operation has two modes, a passive mode and an active mode. Here, in the passive mode, the dedicated graphic LSI 12
The active mode refers to a mode that operates according to an instruction from the PU memory 11 or the like.
Indicates a mode in which the small-sized processor section 12a inside the mode operates independently. In the active mode, the CPU memory 11 is not used, and the internal processor control program section 8b stored in the ROM 8 is sequentially interpreted to display a continuous image. It can be made to have sex. In the passive mode, time progress and display image (= animation)
Is managed by an external controller, that is, by the CPU memory 11 in this embodiment. In the passive mode, the processor unit 12a can be used to generate a series of sprite images in a frame.

The dedicated player 9 shown in FIG. 2 has a CPU memory 11 for controlling a dedicated graphic LSI 12, and operates in a passive mode. Instead of such a dedicated player 9, ie, C
In the case of a device such as the PU memory 11 having no function of controlling the dedicated graphic LSI, the device operates in the active mode.

First, an outline of the operation in the passive mode will be described. The CPU memory 11 interprets data in the ROM 8 or a command sequence input from the external information source 14 and drives the dedicated graphic LSI 12. The program for command analysis is stored in the program ROM 13. The small processor unit 12a of the dedicated graphic LSI 12 stores the animation data 26, the specific image data 23, and the related display data 2 stored in the ROM 8.
4, that is, an image of a frame specified by the CPU memory 11 is generated using the scenario data and the image (audio) data. On the other hand, the CPU memory 11 stores the external information source 1
4 to drive the dedicated graphic LSI 12 for displaying a specific image in the specific image sprite,
The specific image is displayed.

This passive mode is a set of the following programs. The execution control of each program is performed by the processor unit 12a, and each program is terminated by a stop (HALT) instruction.

(1) Title initialization program (HAL
(End with T) (2) Frame drawing program Frame initialization program Back frame drawing program (End with HALT) a) Image unit initialization program b) Image unit drawing program a) Single sprite drawing program Front frame drawing program (with HALT) End) a) Image unit initialization program b) Image unit drawing program a) Single sprite drawing program Display parameter set / display program (end with HALT) In this passive mode, the progress of each frame 20 is
The U memory 11 manages it. The CPU memory 11 instructs the small processor section 12a of the dedicated graphic LSI 12, sets a drawing program start address, and instructs execution start. The small processor unit 12a has a ROM 8
And reads the data therein, issues an execution instruction to the video display processor 12b, and causes it to be executed.
Thereafter, the CPU memory 11 stores the dedicated graphic LSI
By polling the state of the 12 small processor units 12a, the execution of the drawing program is awaited. The small processor unit 12a automatically executes a series of drawing programs, and stops when the last stop (HALT) instruction is executed. On the other hand, the frame progress of each sprite (= scenario)
Is stored in the external processor control data section 8a of the ROM 8 as the animation data 26, and the CPU memory 11 executes the scenario as appropriate while analyzing the structure of the animation data 26.

The CPU memory 11 stores the small processor 1
After instructing the small processor unit 2a, the CPU memory 11 re-executes another process or is inactive.
Issue a command to a. By repeating this, the animation is executed. Thus, in passive mode,
While the CPU memory 11 manages the time including the progress and the repeat of the frame 20, the dedicated graphic LSI 1
The second small processor unit 12a has a function of drawing each sprite. Here, the CPU memory 11
Also controls the operation of each frame at 1/25 second intervals.

On the other hand, the small processor unit 12a instructs the video display processor unit 12b, for example, g
Use the o command to signal the start of work. The video display processor 12b takes in the compressed image data from the ROM 8. Meanwhile, the small processor unit 12a is waiting for the end of the work of the video display processor unit 12b. Thus, the small processor unit 12a controls the video display processor unit 12b.

FIG. 12 and FIG. 13 show such a relationship. The CPU memory 11 reads data related to a scenario from the external processor control data section 8a of the ROM 8, and stores the data in the small processor section 1 of the dedicated graphic LSI 12.
2a is instructed to read and execute the display program in the frame 20. The small processor unit 12a has a ROM 8
And reads the display program from the internal processor control program section 8b, and instructs the video display processor section 12b to capture image data based on the program. Based on this instruction, the video display processor unit 12b fetches the compressed image data from the image data unit 8c of the ROM 8. Note that RO
In the exchange with the M8, the capture of the compressed image data takes the longest time. In addition, for display related to a specific image, the CPU memory 11 directly controls the video display processor unit 12b.

In the passive mode, when the ROM 8 is incorporated in the dedicated player 9, first, the title initialization program operates. This title initialization program is executed only once at the beginning of the incorporation in each of the different ROMs 8, and includes a display mode setting, a natural image sprite display mode designation, and a color condition set according to the panel of the display unit 10. Done. In the case of the active mode, a similar title initialization program is executed.

Thereafter, the specific operation in the passive mode is as follows. First, the sprite drawing program will be described based on the flow shown in FIG. When started, parameters read from the ROM 8 are set in the register section 12c and initialization is performed. When the initialization is completed, decoding of the sprite to the video display processor unit 12b is started. When the decryption is completed, 1
Drawing of two sprites is completed. This is similarly performed for other sprites. The data read from the ROM 8 is stored in the VRAM 16 for two screens, and predetermined data is read from the VRAM 16 to the video display processor unit 12b.

Next, the drawing program for each frame 20 (= 1 screen) will be described. This frame drawing program is composed of a back frame drawing program and a front frame drawing program. Here, the back frame refers to a group of sprites that exist farther behind the group of sprites that the CPU memory 11 itself draws by controlling the video display processor unit 12b of the dedicated graphic LSI 12, and is referred to as a front frame. Refers to a group of sprites that exist further before the group of sprites that the CPU memory 11 itself draws by controlling the video display processor unit 12b of the dedicated graphic LSI 12.

Normally, a back frame, for example, one of the multi-color sprites is drawn, then a specific image sprite is drawn, and finally, a front frame, for example, another one of the multi-color sprites is drawn. The use of each sprite at the time of drawing can be changed as appropriate. In this embodiment, the display of the specific image, for example, the time, is uniquely controlled.
Is directly controlled by That is, normally, when the start address in the ROM 8 is designated by the CPU memory 11, the frame drawing program starts running, and the subsequent processing is managed by the small processor unit 12a. Only the CPU memory 11 directly executes.

The drawing of the back frame is executed by drawing sprites, which are objects of the basic unit having the attributes of the display surface, as many as exist in the frame 20 (see FIG. 15). Note that, also in drawing each sprite, first, the parameters of the register unit 12c are set. FIG. 3 shows the relationship between the CPU memory 11, the dedicated graphic LSI 12, and the data in the ROM 8, and the specific drawing operation.

For drawing the front frame, as shown in FIG. 16, after drawing of the sprite is completed, the timing of switching the display unit 10 is waited. That is, an INH (prohibition) determination step of determining whether or not it is a time zone in which the data for the display parameter set can be transmitted is included.
If the time period is acceptable, the predetermined portion of the image data stored in the VRAM 16 is stored in the register 1.
2c, the register unit 12c sets parameters and switches the display screen. And VRAM
The image data for the second display screen stored in 16 is sent to the display unit 10. If the transmission is prohibited, it is necessary to wait until a time zone in which transmission is permitted.
When only one screen is drawn, a back frame drawing flowchart and a drawing process between back and front drawing described later are not required, and only the flow shown in FIG. 16 is performed.

FIGS. 17 and 18 show a series of flows summarizing the drawing flowcharts shown in FIGS. First, when started, a command to clear the VRAM 16 is issued, and the VRAM 16 is cleared. Thereafter, the process enters a step of drawing a sprite in which a plurality of sprites are gathered. First, the “parameter set” in FIG.
Steps of “sprite initialization parameter set” that integrates “initialization start” and “sprite initialization” are performed. Next, a step of “sprite drawing parameter set” for setting parameters for drawing a sprite is executed. After this,
When a drawing command is input and the input is confirmed, FIG.
5 is executed. After drawing the required number of sprites, stop (HAL
T) Stop drawing by command.

Here, in the initialization at the time of drawing a sprite, each parameter of a blind mask or a simple mask window is set in the register section 12c. In the sprite drawing parameter set, parameters of the writing window, parameters for image compression / enlargement, pallet numbers to be used, and the like are set in the register unit 12c. Here, a blind mask is a mask like a blind attached to a window, and only a portion overlapping the blind mask is drawn. A simple mask is a rectangular mask, and only the inside of the simple mask is drawn. It will be.

After the back frame drawing is completed, the CPU
The process in which the memory 11 directly controls the video display processor unit 12b of the dedicated graphic LSI 12 to draw a sprite is executed. In this embodiment, the CPU memory 11 directly controls the rendering of the specific image sprite.

Thereafter, front frame drawing starts. Then, “sprite initialization parameter set” and “sprite drawing parameter set” similar to those in FIG. 17 are performed. When the drawing command is input and confirmed, the front frame drawing flow shown in FIG. 16 is executed. Then, in the case of “OK” in the “access permission / inhibition” determination step in the “INH” step of FIG.
The display parameters include, for example, a display position of a natural image sprite, a blend coefficient in a blending process, and the like. After the display parameters are set, the display bank, ie, V
The two banks in the RAM 16 are switched and stopped at a timing when the screen does not flicker.

Next, the operation in the active mode will be described. This active mode uses the dedicated graphic L
This mode is performed when there is no control unit such as the CPU memory 11 for controlling the SI 12. For this reason, a self-propelled application is used. Then, it is constituted by a set of the following programs, and each program spontaneously transfers control. That is, since halt is not specified for each program, the program is executed permanently.

(1) Title initialization program (same as passive mode) (2) Frame drawing program Frame initialization program (same as passive mode) Drawing program (same as passive mode) Display parameter set / event processing program These programs Activates the active mode.

A special feature of this active mode is that
The event processing program specifically executes the following processing at the timing of switching the display screen after the drawing program ends. That is, a) waiting for time (dropping frames), b) sound synchronization (waiting for end of reproduction), c) I / O.
There are three branches due to port input. And it is also possible to combine these events.

Here, waiting for time (dropping frames) means a predetermined time (this time is set in units of vertical synchronization time),
The same image is displayed. Sound synchronization (playback wait) is to suspend display switching until the sound flowing on a certain screen ends. The I / O port input enables an operation command to the dedicated graphic LSI 12 to be input through the I / O port, and branches to a predetermined program according to an 8-bit input state. This branch is executed after the display is switched. This I
Examples of the / O port input include inputting 0 bits to jump to another animation, maintaining the current screen until any key input is performed, or displaying a menu. is there.

The present invention can also be applied to a menu device in a food store. Further, as the configuration of the display screen, various screen configurations such as only a multi-color sprite or only a natural image sprite can be employed as appropriate, instead of a screen including a plurality of sprites having different properties.
