And a control signal creating unit 82 for creating the control signal of

Next, the operation of the printer system according to the first embodiment described above will be described with reference to the flowcharts shown in FIGS.

It is assumed that the user operates the application 75
Then, it is assumed that drawing data of a pie chart as shown in FIG. 20 is created, three copies of the pie chart are normally printed, and two copies of a pie chart that is easy to see even by a color-blind person or the like are to be printed.

In this case, as shown in the flowchart of FIG.
Is activated (step 1). The printing mode receiving unit causes the display 12 to display a printing condition setting screen as shown in FIG. The user sets three copies as the number of normal prints and two copies as the number of user auxiliary prints on this print condition setting screen. At this time, when only the normal number of copies is set, the normal print mode is set, and when only the user auxiliary print number is set, the image conversion print mode is set, and the normal print number and the user auxiliary print number are set. in case of,
The multi-print mode is set. That is, here, the user has designated the composite print mode, and the print mode receiving unit has accepted this composite print mode (step 2).

When the number of user auxiliary print copies is set and the mode is changed to the image conversion mode or the composite print mode (step 3), the image conversion mode receiving unit 58 of the user interface 57 is activated, and the image conversion receiving unit 58 is turned on by the image conversion receiving unit 58 shown in FIG. Is displayed on the display device 12 as shown in FIG. Here, when the number of user-assisted printing copies is set, the image conversion mode receiving unit 58 is activated. However, a button indicating the image conversion printing mode is displayed on the printing condition setting screen shown in FIG. A button indicating the composite printing mode may be displayed, and clicking this button may activate the image conversion mode receiving unit 58.

The user assist print setting screen shown in FIG.
As an image conversion form, a contour enhancement form that adds a contour line at a color change in an image indicated by drawing data or enhances a contour line already drawn, and a pattern in a certain pattern area in the image are used. For example, a pattern conversion mode for changing to a mesh pattern or the like and a color conversion mode for changing a color in a certain pattern area in an image are displayed.

When the user looks at the user-assisted print setting screen shown in FIG. 4 and designates one or more of the three image conversion modes, the conversion mode receiving section 58 receives this, and The image conversion unit 65 is notified (step 5).

Upon receiving the conversion form, the image conversion section 65 converts the drawing data according to the conversion form (step 6). Specifically, as shown in the flowchart of FIG. 9, the image conversion unit 65 once reads the drawing data stored in the journal file 61, and first grasps the entire image indicated by the drawing data (step S1). 20). The image conversion unit 65 then converts the read drawing data so as to be converted into an image according to the image conversion form received by the conversion form receiving unit 58 (steps 21 and 22), and the changed drawing The data is written to the journal file 61 (step 23).

When the user looks at the user-assisted print setting screen shown in FIG. 4 and designates an image conversion mode, and wants to preview the converted image corresponding to the image conversion mode, the user can specify a preview mode as shown in FIG. A preview display is designated on the user assistance print setting screen shown in FIG. Preview display section 5 of user interface 57
9 receives this designation and executes a preview display process (step 8). Specifically, preview display section 59
Communicates the fact to the replay manager 56 and, under the control of the replay manager 56, causes the drawing processing unit 52 to read the drawing data after image conversion from the journal file 61 (step 30, FIG. 10). The image is developed in the RGB image data area 62 (step 34). The preview display section 59 displays the RGB image data on the display 1 via the operating system 70.
2, and the converted image is displayed on the display device 12 (step 35).

The user looks at the preview display of the converted image, and if this image is acceptable, specifies printing (step 9). If the user sees the preview display of the converted image and finds that the image is not preferable, he or she specifies the image conversion mode again (step 5).

When execution of printing of the converted image is designated,
The replay manager 56 includes a user interface 57
The drawing processing unit 52 and the CM
The YK binarization processing unit 53 is started. As previously mentioned,
When three copies are set as the number of normal print copies and two copies are set as the number of user auxiliary print copies, the drawing data processing unit 52 first reads the converted drawing data from the journal file 61 (step 40, FIG. 11). ), And converts the drawing data into RGB image data and develops it in the RGB image data area 62 (step 4).
4). Subsequently, the CMYK binarization processing unit 53 outputs the RG
The B image data is converted into CMYK binarized image data, which is developed in a CMYK binarized image data development area 63 (step 45). CMYK binarized image data is stored in CMYK binarized image data development area 6
3, the command conversion processing unit 54
The YK binarized image data is converted into a print command that can be interpreted by the printer 30 (step 46), and the print command is transmitted to the printer 30 via the transmission / reception unit 55 and the operating system 70 (step 4).
7). Thereafter, it is determined whether or not all the print commands have been transmitted (step 48), and if all the print commands have been transmitted, the converted image printing process (step 10) ends. In this case, since the number of user auxiliary printing copies is two, steps 40, 44 to 47 are performed.
Is repeated once more, and the printer 30 prints two copies of the image-converted image, followed by terminating the process.

When the conversion image printing process (step 10) is completed, the conversion mode receiving unit 58 determines whether the received mode is the image conversion mode or the composite printing mode (step 11). For example, it causes the replay manager 56 to execute the printing process of the drawing data that has not been converted, transmits the print command for normal printing three times, and causes the printer 30 to print three copies (step 1).
3). The printing process here is the same as the process shown in the flowchart of FIG. 11, except that the drawing data that has not been converted is handled. If it is determined in step 11 that the mode is not the composite print mode, that is, if the image conversion mode, the process ends.

If it is determined in step 3 that the print mode is the normal print mode, after the execution of printing is accepted (step 12), the above-described printing process of unchanged drawing data is executed. (Step 13).

Next, a specific image conversion form will be described.

For example, when the user selects the outline emphasis mode as the image conversion mode, the pie chart shown in FIG. 20 has a black outline added at the color change in the image as shown in FIG. It becomes an image. Also,
If there is an outline at the color change, but the outline is thinner than a predetermined thickness, the outline is changed to a predetermined thickness. Here, black is adopted as the color of the outline, but various colors such as red and white may be designated.

When the user selects the pattern conversion mode, a plurality of diagonal patterns are added to the solid and light blue area b of the pie chart shown in FIG. 20, as shown in FIG. Color blindness is gray / light blue, pink / gray, yellow-green /
It is said that a combination of colors such as ocher, light green / skin color, and red / green is difficult to recognize. Therefore, the pattern conversion form,
When a color conversion form described later is selected, if there is a combination of the colors exemplified above, among the colors of this set,
The pattern or color of at least one color region changes.
In this case, since the combination of the colors of the region a and the region b of the pie chart shown in FIG. 20 is the combination of the gray / light blue illustrated above, an oblique diagonal line is added to the light blue b region. As an example of the pattern pattern, a grid pattern, a wavy line pattern, and the like can be considered in addition to the oblique line pattern. Although the pattern of only the b region is changed here, the pattern of the b region and another region may be changed. Further, if there is no color combination that is difficult for a color-blind person to recognize in the image indicated by the drawing data, the pattern is not changed, for example, “Easily viewable without executing the pattern change. The image may be displayed. The pattern may be changed in a specific area or some areas.

When the user selects the color conversion mode,
The pie chart shown in FIG. 20 has a gray a
The area is changed to white, the light blue b area is changed to blue, and the light yellow c area is changed to red. Here, in changing the color of each area, the color of each area is determined so that a combination of colors that are difficult for a color-blind person to recognize is not included. Note that, here, the colors of all the regions in the image indicated by the drawing data are changed. However, if there is a combination of colors that are difficult for a color-blind person to recognize, the region of one of the colors May be changed only. Further, if there is no color combination that is difficult for a color-blind person to recognize in the image indicated by the drawing data, as in the case of the above-described pattern conversion mode, for example, “ It is possible to display an image which is easy to see even if it is not provided. ", Or a specific area or some areas may be changed in color. In this case, the color of each region is determined so that the color change does not include a combination of colors that are difficult for a color-blind person to recognize.

When the user selects two or more conversion modes from among the three conversion modes as the image conversion modes, the image conversion in which the conversion modes are combined is performed. For example, assuming that the user selects the contour enhancement mode and the color conversion mode, the pie chart in FIG. 20 adds a contour line and also changes the color of each area.

As described above, in the present embodiment, it is possible to produce a printed image with a clear image that is easy to see even for a color-blind person by simply specifying the image conversion mode by the user.

In this embodiment, the outline conversion mode, the pattern conversion mode, and the color conversion mode have been described as the image conversion modes. However, a conversion mode in which the lines in the image are made thicker or the colors of the lines are changed. There may be a conversion form for increasing the size of the character.
