Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image editing apparatus, for example, an image editing apparatus for editing pre-created image data on a screen of a display according to instruction contents indicated in an instruction sheet. .

[0002]

2. Description of the Related Art As is well known, printed matter and electronic printed matter are
It is composed of multiple types of parts such as sentences, headline letters, logos, pictures, and illustrations. In the editing process, after the data of such a plurality of parts is created, it is laid out at a predetermined position. The completed data becomes a printed matter through a plate making process and a printing process, and is distributed as an electronic publication such as a CD-ROM.

In the above-mentioned editing work, it is rare that one edition work produces a publication in a perfect state, and normally, a proofreading, a correction, and a change are repeated to finish the publication in a perfect state. Go.

In proofreading, re-editing work is performed based on an instruction sheet instructing correction points, but there are cases in which corrections have not been made correctly due to correction errors or the like. Therefore, it is necessary to check whether the corrected data is correctly corrected as instructed, or whether an unnecessary change is made to a portion without a correction instruction, as compared with the data before correction.

In the conventional printing process, since these checks are performed after the printing plate is made, it has been said to be a plate inspection work. However, the output to the printed matter other than the CD-ROM is increasing, and Even for printed matter, a device that directly prints without a printing plate has been developed, and it is necessary to check it before printing it.

[0006] Conventionally, as a method for proofreading before making a printing plate, there is a method disclosed in Japanese Patent Laid-Open No. 106965/1994
(Referred to as the first conventional technique) and Japanese Patent Laid-Open No. 7-219202.
There is a technique disclosed in Japanese Patent Publication (hereinafter, referred to as a second conventional technique).

In the first prior art, the history data indicating the correction history of the corrected image element is stored together with the image data representing the calibration image, and the corrected image is recorded based on the image data and the history data. An image for recalibration in which elements are painted in a predetermined color is created, and the image for reconstruction is output from a printer or displayed on a CRT.

On the other hand, the second conventional technique is the RIP before correction.
The expanded image data is stored and compared with the corrected RIP expanded image data to detect the difference and display it on the display device.

[0009]

The first prior art described above only outputs a different portion between the image before correction and the image after correction in a designated color, so that a change in the shape of the part can be detected. However, I could not express the change in color tone. In addition, it was difficult to compare whether the correction result matches the instruction in the instruction sheet.

In the second prior art, since the image data after RIP development are compared with each other, it is possible to express the change of the color tone. However, since the image data after RIP development has a large amount of data, the data The transfer takes time, and a large-capacity storage device is required to store the data. Therefore,
The apparatus becomes large in scale and high in cost, and it takes a long time for processing.

Further, in both the above-mentioned first and second conventional techniques, in order to confirm whether or not the changed portion is corrected as instructed, the image displayed on the display and the instruction sheet are written. It is necessary to visually compare the written instructions one by one, which puts an excessive burden on the operator. Also,
The proofreading processes of the first and second prior arts described above are not linked with the editing work, and therefore, when a portion requiring re-correction is visually found, the editing work cannot be immediately started, There was also the problem of poor workability.

Therefore, an object of the present invention is to easily confirm whether the image is corrected properly according to the difference between the image before correction and the image after correction and the instructed contents, and the image editing apparatus with excellent working efficiency is provided. Is to provide.

1 is a block diagram showing the structure of an image editing apparatus according to an embodiment of the present invention. In FIG. 1, the image editing apparatus according to the present embodiment includes a CPU 1, a system bus 2, a main memory 3, an image memory 4, and
It includes an interface 5, a keyboard 6, a mouse 7, a reading scanner 8, a CRT display 9 and a storage device 10.

The CPU 1 is connected to the CPU 1 via the system bus 2.
Main memory 3, image memory 4 and interface 5
Are connected. A keyboard 6, a mouse 7, a reading scanner 8, a CRT display 9 and a storage device 10 are connected to the interface 5. The storage device 10 is composed of, for example, a hard disk device.

The CPU 1 operates according to a software program stored in the storage device 10. The software program may be preinstalled in the storage device 10, but may be stored in a portable storage medium (CD-RO).
M, floppy disk, etc.) and may be provided or supplied via a communication line. When the software program is provided or supplied on a portable storage medium or online, the software program is installed in the storage device 10, read by the CPU 1, and executed.

FIG. 2 is a diagram showing an example of a display screen of the CRT display 9 shown in FIG. In FIG. 2, an image display window 11, a menu box 12, and a display switching palette 13 are displayed on the CRT display 9. In the image display window 11, the image of the page being edited, the comparison result, and the like are displayed. The menu box 12 includes a plurality of control bars 12a-12d. Move the cursor to the designated control bar and click mouse 7
PU1 enters the corresponding operating mode.

3 and 4 show the display switching palette 13.
Two display examples are shown. This display switching palette 1
In 3, an icon corresponding to each data stored in the main memory 3 is displayed. For example, in the display switching palette 13 shown in FIG. 3, an icon IC1 corresponding to the instruction data D obtained by reading the instruction, an icon IC2 corresponding to the image data A before editing, and an image being edited. An icon IC3 corresponding to the data B and an icon IC4 corresponding to the comparison result data C which is the comparison result of the image data A and B are displayed.

As the data stored in the main memory 3 increases, the icon display in the display switching palette 13 also expands. For example, FIG. 4 shows the display contents of the display switching palette 13 after the editing corresponding to the two instructions has been performed. Although the display area of the display switching palette 13 is limited, by operating the scroll bar 14 with the mouse 7 to scroll the display content, the entire display content can be viewed even when there is a large amount of display data.

In the image display window 11 described above, the data indicated by the icon displayed in the display switching palette 13 is displayed. More specifically, the data corresponding to the highlighted icon is displayed in the image display window 11. For example, in FIG. 3, since the icon IC3 is highlighted, the image display window 11 displays the image data A being edited. The display content in the image display window 11 is switched by selecting the control bar 12b in the menu box 12 and then selecting an arbitrary icon in the display switching palette 13.

In this embodiment, it is also possible to display the data obtained by combining the two data selected from the display switching palette 13 in the image display window 11. In this embodiment, two types of operation methods are prepared as operations for executing such composite display. The first operation method is a method of selecting any icon in the non-inverted display state from the display switching palette 13 and dragging and dropping the selected icon into the image display window 11. In this case, the image display window 11 has already been displayed.
The data displayed inside and the data corresponding to the dragged and dropped icon are combined and displayed. The second operation method is a method in which one icon selected in the display switching palette 13 is dragged and superimposed on the other icon. In this case, the data corresponding to the one icon and the data corresponding to the other icon are combined and displayed.

5 to 6 are flowcharts showing the operation of the above embodiment. The operation of the above embodiment will be described below with reference to FIGS.

Initially, it is assumed that a plurality of image data before editing are stored in the storage device 10. Further, it is assumed that the reading scanner 8 previously reads the instruction sheet for each image data before editing, and the instruction sheet data obtained by the reading is stored in the storage device 10.

In this state, the operator operates the keyboard 6 or the mouse 7 to select the image data to be edited. In response, the CPU 1 reads the corresponding image data from the storage device 10, converts it into display data, and then stores it in the image memory 4 (step S101).
Accordingly, the selected image before editing is displayed in the image display window 11 of the CRT display 9 (step S
102). Next, the CPU 1 stores the display data of the pre-edition image stored in the image memory 4 in the main memory 3 (step S103). Accordingly, the icon IC2 of FIG. 3 is displayed in the display switching palette 13. Next, the CPU 1 reads out the instruction data corresponding to the selected unedited image data from the storage device 10 and converts it into display data (step S104). Next, CPU1
Displays the display data of the instruction data in the main memory 3
(Step S105). Accordingly, the icon IC1 of FIG. 3 is additionally displayed in the display switching palette 13.

Next, the CPU 1 causes the image display window 1
Editing work is performed on the image before editing displayed in 1 (step S106). This editing work is performed in response to the operation of the keyboard 6 or the mouse 7 by the operator. When the editing work is completed, the display data of the edited image is stored in the main memory 3. Accordingly, the icon IC3 of FIG. 3 is additionally displayed in the display switching palette 13.

Next, the CPU 1 reads the display data of the image before editing and the display data of the image after editing from the main memory 3 and compares them (step S107). This comparison is performed by calculating the exclusive OR of both display data for each pixel. Here, the exclusive OR is an operation of outputting binary data which is "1" when the density values of the two do not match and "0" when they match. Next, the CPU 1 stores the comparison result data in the main memory 3 (step S108). Accordingly, the icon IC4 of FIG. 3 is additionally displayed in the display switching palette 13.

Next, the CPU 1 determines whether or not the search mode is instructed by the operator (step S1).
09). This search mode is designated by selecting the control bar 12a in the menu box 12 with the mouse 7. When the search mode is not instructed, the CPU 1 determines whether the operator has instructed the display switching mode (step S110). This display switching mode is designated by selecting the control bar 12b in the menu box 12 using the mouse 7. When the display switching mode is instructed, the CPU
1 executes display switching processing (step S111).

FIG. 6 shows the subroutine step S11.
1 shows details of No. 1. Referring to FIG. 6, the CPU 1
It is determined which icon in the display switching palette 13 has been selected by the operator (step S20).
1) The selected icon is highlighted (step S)
202). Next, the CPU 1 determines that the selected icon is 1
It is determined whether or not (step S203).

If only one icon is selected, the CPU
First, the display data corresponding to the selected icon (pre-edition image, post-edition image, comparison result data or display data of instruction data) is acquired from the main memory 3 (step S204). Next, the CPU 1 stores the acquired display data in the image memory 4. As a result, the display content in the image display window 11 is switched to the image corresponding to the selected icon (step S205). After that, the CPU 1 returns to the main routine of FIG.

On the other hand, the case where the number of selected icons is not one, that is, the case where there are two icons will be described. As described above, two icons are selected by dragging and dropping the icon in the display switching palette 13 into the image display window 11 or by overlapping the two icons in the display switching palette 13. In this case, CPU1
Aligns the display data corresponding to one icon with the display data corresponding to the other icon (step S206). That is, when the synthesis operation of the two display data is performed, the corresponding pixels are matched with each other.

Next, the CPU 1 selects a pixel which is the object of the combining operation from the data corresponding to the selected icon, and acquires the corresponding pixel data from the main memory 3 (step S207). Next, the CPU 1 determines the mode of the synthetic operation (step S208). In the present embodiment, it is possible to select and set one combining operation mode in advance from a plurality of kinds of combining operation modes. In step S208, it is determined which combination calculation mode is set. Next, the CPU 1 executes the combining operation on the target pixel data according to the set combining operation mode (step S209). Then C
PU1 determines whether or not the combining operation for all the pixels is completed (step S210), and if not completed, the target pixel is updated and the combining operation is repeated (step S20).
7-S209). When the composition calculation for all the pixels is completed, the CPU 1 stores the composition calculation result in the image memory 4 and displays it on the image display window 11 of the CRT display 9 (step S211). After that, the CPU 1
Return to the main routine of.

Here, the kind of the synthesis operation executed in step S209 will be described. In this embodiment,
As selectable combination calculation modes, a halftone combination mode, a hatching combination mode, a difference combination mode, an Add combination mode, an EOR combination mode, and a Max combination mode are prepared. Hereinafter, each combination calculation mode will be described.

(1) Halftone Synthesis Mode In the halftone synthesis mode, the density value of one pixel to be synthesized is a
% And the density value of the other pixel is b%, the displayed density value is calculated by the following equation (1). a * 0.5 + b * 0.5 (1) That is, in the halftone combination mode, the densities of both images to be combined are reduced to 50% overall, and the images are displayed together. Such a synthesizing method is particularly effective when it is desired to superimpose the contents of the instruction sheet on the edited image. In the conventional actual work, it is often done to check whether the correction is performed as instructed by covering the edited image with a semitransparent tracing paper in which the instruction content is described. In the halftone synthesis mode, a visual effect equivalent to this can be realized on the screen of the CRT display 9. When combining color images, each YM
The calculation is performed for each CK version.

(2) Hatching composition mode In the hatching composition mode, both images to be composed are
By alternately displaying every other pixel, overlapping display is performed without changing the density value of the pixel. For example,
One image to be combined and the other image are combined in a checkered pattern. Such a synthesizing method is particularly effective when comparing density values. For example, when the image before editing and the image after editing are combined and displayed in the hatching combining mode, it is possible to confirm easily because there is unevenness in a portion having a difference in density value.

(3) Difference combining mode In the difference combining mode, the density value of one pixel to be combined is a.
%, And the density value of the other pixel is b%, the displayed density value is calculated by the following equation (2). ab (2) That is, in the difference combination mode, the density of the difference between the two images to be combined is used as the display density. Such a synthesis method
Similar to the hatching synthesis mode (2) above, it is particularly effective when comparing density values. However, in the difference synthesis mode, only the portion having a difference in density value is displayed in dots, so that the relationship with the shape is difficult to understand. In the difference synthesis mode, the calculation result by the above equation (2) is 0%.
If less than, the display density value is limited to 0%. Also,
When synthesizing color images, calculation is performed for each YMCK plate.

(4) Add Compositing Mode In the Add compositing mode, assuming that the density value of one pixel to be composed is a% and the density value of the other pixel is b%, the displayed density value is calculated by the following equation (3). Calculate a + b (3) That is, in the Add combination mode, the added density value of both images to be combined is set as the display density value. Such a synthesizing method is particularly effective when it is desired to superimpose the content of the instruction sheet on the edited image, as in the halftone synthesizing mode of (1) above. In the halftone synthesizing mode, since the densities of both images to be synthesized are reduced to 50% respectively and the composite display is performed, the images may become thin and difficult to see.
Since the image is displayed dark in the Add compositing mode, it is effective in such a case. In addition, in the Add combination mode, when the calculation result by the above equation (3) exceeds 100%, the display density value is limited to 100%. Further, when a color image is combined, the calculation is performed for each YMCK plate.

(5) EOR composition mode In the EOR composition mode, assuming that the density value of one pixel to be composed is a% and the density value of the other pixel is b%, the displayed density value is expressed by the following equation (4). Calculate EOR (a, b) (4) That is, in the EOR combining mode, the exclusive OR of the images to be combined is calculated and displayed as in the case of creating the comparison result data. Such a synthesizing method is particularly effective when comparing density values, as in the difference synthesizing mode of (3) above. However, in the EOR composition mode, only the portion having a difference in density value is displayed in dots, so that the relationship with the shape is difficult to understand.

(6) Max combining mode In the Max combining mode, assuming that the density value of one pixel to be combined is a% and the density value of the other pixel is b%, the displayed density value is expressed by the following equation (5). Calculate Max (a, b) (5) That is, in the Max combination mode, the density value of one pixel to be combined with the other pixel is compared, and the larger density value is set as the display density value. If you want to combine color images,
The calculation is performed for each YMCK version.

Returning to FIG. 5 again, the CPU 1 determines whether or not the end mode is instructed by the operator (step S112). This termination mode is indicated by selecting the control bar 12d in the menu box 12 with the mouse 7. When the end mode is instructed, the CPU 1 ends the operation. On the other hand, if the end mode is not instructed, the CPU 1 executes step S10.
Return to operation No. 9.

When the search mode is instructed in step S109, the CPU 1 searches for the edited portion and enlarges and displays the searched portion (step S113). Details of this subroutine step S113 are shown in FIG. In FIG. 7, the CPU 1 firstly determines that the main memory 3
The comparison result data stored therein (data indicating the comparison result between the image before editing and the image after editing) is searched for each pixel (step S301), and the currently searched pixel is turned on.
It is judged whether or not it is in the state (step S30).
2). When the image before editing is different from the image after editing, the pixel at the corresponding position in the comparison result data is in the ON state. If the pixel currently being searched is not in the ON state, the CPU 1 determines whether the search has been completed for all pixels (step S303), and if not completed, the operations of steps S301 and S302 are repeated. When it is confirmed that all the pixels are not in the ON state, the CPU 1 displays "no difference" on the CRT display 9 (step S304), and returns to the main routine of FIG.

On the other hand, when a pixel in the ON state is found, the CPU 1 determines a continuous area where the pixels in the ON state are continuous (step S305). And CP
U1 acquires the maximum coordinate value and the minimum coordinate value of the continuous area for each of the horizontal axis and the vertical axis of the Cartesian coordinate system (step S306). Next, the CPU 1 performs coordinate conversion on the comparison result data stored in the main memory 3 so that the maximum coordinate value and the minimum coordinate value obtained in step S306 match the rectangular display area of the image display window 11. Perform (step S307). next,
The CPU 1 writes the coordinate-converted comparison result data in the image memory 4 and displays the comparison result data in the image display window 11 (step S308). At this time, in the image display window 11, a continuous area in which pixels in the ON state are connected is enlarged and displayed. Therefore, the operator can enlarge and see the portion changed by the editing work, and can easily confirm whether the correct correction has been made. Then C
The PU 1 puts the image parts displayed in the image display window 11 into a selected state, that is, a reeditable state (step S309). This makes it possible to immediately start editing work when it is determined that re-editing is necessary. After the operation of step S309, the CPU 1 executes the process shown in FIG.
Return to the main routine of.

Referring again to FIG. 5, CPU 1 determines whether the re-editing mode is instructed by the operator (step S114). This re-editing mode is designated by selecting the control bar 12c in the menu box 12 with the mouse 7. If the operator sees the comparison result enlarged and displayed in the image display window 11 and determines that the re-editing is not necessary, the operator does not instruct the re-editing mode but the search mode (step S109). In this case, the CPU 1 searches for the next continuous area and enlarges and displays it in the image display window 11 (step S113).
On the other hand, when the re-editing mode is instructed, the CPU 1 returns to the operation of step S106 and re-edits the continuous area searched at that time.
