Description

  The present invention relates to a display processing apparatus that displays a display area for performing color display on a display screen.

  Conventionally, in a document processing apparatus such as a word processor, the display content of a background area serving as a background for document data displayed on a text screen is fixed by a display color or the like arbitrarily set in advance by a user. That is, unless the user changes the content of the background display, the same content of the background display is always performed.

  However, if the display color of the document data is the same system as the background, the contrast between the document data and the background will be poor, and the document data will be buried in the background. Conversely, if the contrast is too strong, the background will not be in harmony. There was a thing. This applies not only to display colors but also to the case where the background is modified by shading or the like, and not only to documents but also to the case where table data and illustration images are output. In this case, changing the display content of the background each time will make the data stand out, harmonize, or interesting, but the change work is extremely troublesome and time consuming. However, there is a problem that it places a heavy burden on the user.

  An object of the present invention is to be able to change the background color of a display area displayed on a display screen to a background color according to the display color of the display area.

  The invention described in claim 1 stores a plurality of display colors, stores a background color corresponding to each display color, a display means for displaying document data on a display screen, and the display screen An area determination means for determining whether or not a background area exists outside a display area where the document data is displayed, and when it is determined that the background area exists on the display screen, the display of the document data Display color discrimination means for discriminating the display color of the area, and a background color corresponding to the determined display color is selected with reference to the storage means, and the background area on the display screen is selected according to the selected background color. Background display means for displaying.

  The invention described in claim 2 stores a plurality of display colors, stores a background color corresponding to each display color, and each display data displayed in a display area displayed on the display screen. A color is extracted, a discrimination unit that discriminates a color that is frequently used based on each of the extracted colors, and a background color corresponding to the discriminated color is selected with reference to the storage unit, and the selected And background display means for displaying a background outside the display area or a background of the display data in the display area by a background color.

According to the first aspect of the present invention, if there is a background area outside the display area of the document data displayed on the display screen, the background color of the background area corresponds to the display color of the display area. Can be automatically determined and displayed.
According to the second aspect of the present invention, by determining the display color that is frequently used from the color of each display data displayed on the display screen, the background color corresponding to the display color is displayed on the display data. Can be automatically determined and displayed as the background color of the outside of the display area or the background.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a block diagram of a word processor that performs color image processing. The CPU 1 is a central processing unit that controls the overall operation of the word processor in accordance with various programs stored in the ROM 2 and the like. For the input unit 3, the color display unit 4, and the color printing unit 5 that are input / output peripheral devices. Control its input / output operations. The ROM 2 is a read-only memory having an illustration image memory 2-1 that stores various programs and character font data for display / printing, and stores various illustration images in association with illustration names.

  The input unit 3 includes a keyboard and a mouse, and character string data input from the input unit 3 is displayed and output on a text screen of the color display unit 4. Here, when the conversion key on the keyboard is operated, the CPU 1 refers to the kana-kanji dictionary memory 6 to convert the input kana character string into a kanji mixed sentence, and the conversion determined according to the operation of the confirmation key. The character string is stored in the document memory 7. At this time, if emphasis control information (for example, color information) for emphasizing all or part of the document data is arbitrarily designated from the input unit 3, the CPU 1 associates the emphasis control information with the document data and records the document. The document data is set in the memory 7 and the document data on the text screen is highlighted based on the highlight control information. When an arbitrary illustration inserted into the document is designated from the input unit 3, the CPU 1 stores the illustration name in the document memory 7 and reads the illustration image from the illustration image memory 2-1, and displays it on the text screen. Display output. At this time, if the illustration image is a color image, color display is performed accordingly.

  The background color determination table 8 is a table for determining a color that modifies a background area as a background for the document display area. FIG. 2 is a diagram showing the relationship between the document display area and the background area, and the margin area on the display screen for the previously formatted paper is the background area. FIG. 3 exemplifies the contents of the background color determination table 8. Color information (color code) for designating color output of document data is set in the document memory 7 as emphasis control information, or a color illustration in the document. When an image is inserted, the background color determination table 8 determines whether the background area is modified with a similar color or a complementary color for the color, and the document color code and the background color code for each similar color and complementary color. Is stored. That is, for the similar colors, for example, the color code (25) indicating “red” is stored as the background color code in association with the red document color codes (1) to (25), and the red color is used for the complementary colors. A color code (100) indicating “blue green” is stored as a background color code in association with the document color codes (1) to (25).

  Here, when various color codes are set as emphasis control information in the document memory 7 or when a color illustration image is inserted in the document, the CPU 1 determines the amount (area) of the color used. It is detected for each system and is set in the color system classification memory 9-1 in the RAM 9. FIG. 4 shows the contents of the color system classification memory 9-1 and stores the amount (area) of colors used for each color system. Here, when determining the color that modifies the background area, the CPU 1 refers to the color system classification memory 9-1 and searches for the most frequently used color system, and the background color determination table based on this color system. The background color is determined with reference to FIG. When detecting the amount of used color, the color use area is obtained for each color system based on the number and size of characters designated by color or the color range, number of images, and image size of a color illustration image. However, it is not necessary to obtain it strictly, and it is sufficient to obtain it roughly.

  Next, the operation of the word processor configured as described above will be described with reference to the flowcharts shown in FIGS. FIG. 5 is a flowchart showing an overview of the overall operation. When the power is turned on, the CPU 1 starts executing the operation according to the flowchart shown in FIG. First, in an input waiting state, the CPU 1 performs input analysis in response to an input from the input unit 3 (step A1), and in accordance with the analysis result, document creation processing (step A2), document editing processing (step A3), screen Scroll processing (step A4), background modification content designation processing (step A5), printing processing (step A6), and the like are executed.

  Here, the background modification content designation processing is performed when the background color code is determined based on the document color code, the same color code that determines the color code similar to the document color code as the background color, the document color code and the complementary color relationship Is switched according to a user designation between a complementary color mode for determining a color code as a background color or a normal mode for determining a background color regardless of the document color. In addition, a process of switching whether or not the background area is patterned by gradation processing according to user designation is performed. Note that the gradation process is a process in which the background color is gradually changed to change the pattern, but the patterning is arbitrary.

  Now, when the document creation process (step A2), the document edit process (step A3), and the screen scroll process (step A4) are executed, the process proceeds to the background process of steps A7 to A15. That is, the document display area on the display screen is discriminated (step A7), and it is checked whether there is a blank area excluding the document display area on the display screen, that is, a background area as shown in FIG. 2 (step A8). . If there is no background area, the following background processing is not performed and the process returns to step A1, but if there is a background area, any one of the similar color mode (step A9), the complementary color mode (step A10), and the normal mode is selected. Check if it is specified. If a similar color mode is specified, display processing using a similar color for the background (step A11) is executed. If complementary color mode is specified, display processing using a complementary color for the background is executed. (Step A12). If the normal mode is designated, a background pattern is created based on the same processing as usual, that is, a color code arbitrarily designated by the user (step A13), and the document display pattern and the background pattern are obtained. Composition is performed on the video RAM in the color display section 4 (step A14), and this composition pattern is output on the display screen (step A15).

  FIG. 6 is a flowchart showing a display process (step A11 in FIG. 5) using a similar color for the background. First, the CPU 1 extracts data such as characters, illustrations, and figures having color elements from the display target data for one screen (step B1), and detects the amount (area) of the used color for each color system. The color system classification memory 9-1 is set, and when such detection processing is completed, the color system classification memory 9-1 is searched to determine the color system most frequently used (step B2). . Then, the background color determination table 8 is searched based on the determined color system, the background color code is read from the similar color area, and the background color is selected (step B3). Next, it is checked whether there is a gradation designation (step B4), and if there is, a background pattern of the gradation pattern is created using the selected background color (step B5). If there is no gradation designation, the selected background color is used. A background pattern for uniformly painting is created (step B6). Then, the display target data for one screen is converted into a display dot pattern, a composite pattern is generated by combining the display pattern and the background pattern (step B7), and the composite pattern is displayed and output (step B8).

  Here, FIG. 9 shows a display example in this case, where (A) shows a case where a gradation pattern is not applied, and (B) shows a case where a gradation pattern is applied. In the display example shown in FIG. 9A, a green circle with a flower illustration is arranged at the center of the document in the document display area, and yellow semicircles are arranged at the top and bottom. It is a thing. In the background areas existing on the left and right sides of the document display area, yellow-green color similar to the color element of the document display area circle is selected and displayed as the background color. In other words, the color elements in the document display area are green and yellow, and the color of the entire screen is harmonized and coordinated by using the same color yellow-green as the background color. In the display example of FIG. 9B, the display content of the document display area is the same as that of FIG. 9A, but the background area is provided with a gradation pattern using yellow-green as the background color. That is, in the left and right background areas, the portion corresponding to the flower illustration is the lightest, and a gradation pattern is applied which gradually darkens from this portion in the vertical direction.

  Next, step A12 (display processing using a complementary color for the background) in FIG. 5 will be described with reference to the flowchart shown in FIG. This display process is basically the same as the display process shown in FIG. 6 and will not be described in detail. However, when the background color is selected by referring to the background color determination table 8, the background process is performed. The difference is that it is performed by referring to the contents of the complementary color area of the color determination table 8. That is, Steps C1 and C2 are the same processing corresponding to Steps B1 and B2 in FIG. 6, but in Step C3, the complementary color area of the background color determination table 8 is searched, and the color of the most frequently used document color A background color that is complementary to the system is selected. Steps C4 to C8 are similar processes corresponding to steps B4 to C8 in FIG. In this way, the color that is complementary to the color most used in the document display area is displayed as the background color, so the entire display screen is contrasted and the contents of the document display area stand out. Is possible.

  FIG. 8 is a flowchart showing step A6 (printing process) of FIG. This printing process shows the operation contents when the similar color mode is specified, and is basically the same when the complementary color mode is specified. Therefore, the printing process corresponding to the complementary color mode is not shown in the figure. Yes. First, the CPU 1 extracts data such as characters, illustrations, and figures having color elements from the print target data for one page (step C1), and detects the amount (area) of the used color for each color system. The color system classification memory 9-1 is set, and when such detection processing is completed, the color system classification memory 9-1 is searched to determine the color system most frequently used (step C2). . Then, the background color determination table 8 is searched based on the determined color system, the background color area is read from the similar color area, and the background color is selected (step C3). Next, it is checked whether there is a gradation designation (step C4). If there is, a background pattern of a gradation pattern is created using the selected background color (step C5). If there is no gradation designation, the selected background color is selected. A background pattern for uniformly painting is created (step C6). Then, the print target data for one page is converted into a print dot pattern, a composite pattern is generated by combining the print pattern and the background pattern (step C7), and the composite pattern is printed out (step C8).

  As described above, the display content of the background area as a background can be displayed in color according to the color elements in the document display area, and the similar color mode specified in advance or According to the complementary color mode, the color display in the background area can be displayed in the similar color or the complementary color with respect to the color elements in the document display area. Therefore, it is possible to make the entire screen have a harmonious sense of cooperation and to enhance the contrast of the entire screen to make the contents of the document display area stand out. This applies not only to display but also to printing. In particular, the background color is determined based on the color most frequently used as the document color, which is more effective. Furthermore, since it is possible to arbitrarily specify whether or not to apply a gradation pattern to the background area, it is possible to express more varied joy.

The present invention is not limited to the above-described embodiment, and may be as follows.
That is,
(1) In the above embodiment, the background area is a blank area excluding the document display area that has been formatted in advance. However, the background area is not limited to this and is arbitrary. For example, FIG. 10 shows an example in which the background of the document is entirely the background area in one page. In other words, the background area is the background area except for the three image areas on which the flower illustrations are drawn. Thus, it becomes possible to harmonize and blend the three images into the background. In addition, the background area may be a window. That is, when a window is opened in the display screen, the window background or window line color may be changed based on the document color for the document in the window.

  (2) In the above embodiment, when the background color is determined based on the document color, the background color is determined based on the most frequently used document color on one screen or one page. However, one background color may be associated with one document color, and the background color may be changed finely (for example, for each line) according to the document color.

  (3) Furthermore, the background color may be changed depending on the character size, or the background color may be changed depending on the character type. For example, the background color may be changed such that the 12-point character is red, the 9-point character is blue, or the Chinese character is red, the English is blue, the brush is yellow, the Gothic is green, and so on.

  (4) In the above embodiment, the background color is changed based on the document color. However, based on the emphasis state (for example, underline, upline, enlarged character, italic character, etc.) that cooperates with the document. The background area may be shaded, hatched, hatched, or patterned. That is, the modification content for modifying the background region may be changed based on how the output target data is emphasized and output.
