  The present invention relates to an image processing apparatus that performs a color arrangement adjustment process for adjusting a partial color arrangement in an image to be processed, a control method therefor, and a program.

  In recent years, graphic software for creating illustrations and designing web pages using a computer has become widespread. If you try to adjust the color scheme in an image such as an illustration or web page design created using a computer, it will occur between adjacent colors and background colors even if you make adjustments while referring to each color individually. Due to the effect of the perception effect of various colors, a color set by considering a single color may not appear as expected in the image.

  In such a case, individual readjustment is performed for the corresponding color and its surrounding colors. In the color designation and color adjustment for a single color as in the conventional graphic application, each color designation is switched. It needs to be adjusted individually, and it takes a lot of effort to achieve the desired color appearance.

  For example, there are Patent Documents 1 to 3 as apparatuses and methods for dealing with such a problem.

  Patent Document 1 discloses a technique for extracting an arbitrary color included in a color image and correcting it to a predetermined color, and a technique for preserving the naturalness of the image before adjustment in the image after adjustment.

  Patent Document 2 discloses a technique for appropriately and easily adjusting the color scheme of an image image pasted on a stage on an editing screen by an authoring tool or the like.

Patent Document 3 discloses a technique for converting an existing image into an image in which the colors of the original image are well reflected by automatically reflecting the color of the original image.

  FIG. 2 is a diagram illustrating an operation example of the color arrangement adjusting system according to the embodiment of the present invention.

  FIG. 2 shows an image display window 21 and a color arrangement adjustment window 22 displayed on the display 11.

  The image display window 21 is a screen in which the computer 14 generates an image to be processed by a program recorded in the storage device 13 and displays it on the display 11.

  The color arrangement adjustment window 22 is a user interface for the computer 14 to adjust the color arrangement of the image displayed in the image display window 21 by a program recorded in the storage device 13. The color arrangement adjustment window 22 generates a desired color based on the adjustment color display unit 31 that displays an adjustment color for adjusting the image to be processed and the adjustment color displayed on the adjustment color display unit 31. An adjustment color operation unit 32 for performing the operation is configured.

  Next, a detailed configuration of the color arrangement adjustment window 21 will be described with reference to FIG.

  FIG. 3 is a diagram showing a detailed configuration of the color arrangement adjustment window according to the embodiment of the present invention.

  In the color arrangement adjustment window 22, rectangular areas 31 a and 31 b for displaying two colors (adjustment target colors) designated in the processing target image displayed in the image display window 21 are displayed in the adjustment color display unit 31. . The rectangular areas 31a and 31b are spaced from each other so as to reduce the change in color appearance due to the effect of the color perception effect between the colors displayed in the respective areas. It is displayed on a small background color.

  In the adjustment color operation unit 32, in order to adjust the color arrangement of the processing target image displayed in the image display window 21, the perception effect of the two adjustment target colors displayed in the adjustment color display unit 31 is obtained. Color information of lightness, saturation, and hue for each of the symbol display unit 33 that displays various symbols for confirmation and the two adjustment target colors specified in the processing target image displayed in the image display window 21 Is composed of a slider control group 35 for individually adjusting. In the present embodiment, as color information used for adjusting the adjustment color, brightness, saturation, and hue that directly affect the intensity of the color perception effect of the operator are used. However, the present invention is not limited to this. is not. For example, other color information such as RGB values and YMC values may be used as color information.

  The processing corresponding to each operation of the slider control group 35 is realized by executing a program recorded in the storage device 13.

  The slider control group 35 can use other types of controls as long as it is a color adjustment function capable of realizing an equivalent function. Alternatively, an input field in which a desired color information value can be input by inputting a numerical value, and a spin control combining a numerical value input field and two button controls for increasing / decreasing the numerical value may be used.

Can be moved up and down. The operator can adjust the color arrangement while comparing the two adjustment target colors displayed on the adjustment color display unit 31 with the same color on the symbol displayed on the symbol display unit 33.

  Next, the color arrangement adjustment processing of the present embodiment will be described with reference to FIG.

  FIG. 4 is a flowchart showing color arrangement adjustment processing according to the embodiment of the present invention.

[Specify color for adjustment]
First, in step S <b> 41, the operator designates an adjustment target color in an image in the image display window 21 on the display 11 via the operation unit 12.

  For example, when a mouse is used as the operation unit 12, this designation is realized by clicking on an area including the color to be adjusted in the image.

  For example, in the image in the image display window 21 of FIG. 2, when the mouse cursor is pointed and clicked on a rectangular area in the ellipse, the color of the rectangular area becomes the adjustment target color.

  Based on this designation operation, the display state of the color adjustment window 22 is automatically updated by the process of FIG.

  Here, the display control process of the color arrangement adjustment window will be described with reference to FIG.

  FIG. 5 is a flowchart showing display control processing of the color arrangement adjustment window according to the embodiment of the present invention.

  First, in step S51, the display of the rectangular areas 31a and 31b displaying the two adjustment colors displayed on the adjustment color display unit 31 is updated. At that time, the display of the rectangular area 31b is updated to the color currently displayed in the rectangular area 31a, and then the display of the rectangular area 31a is updated to the color specified in step S41.

  By this method, when it is desired to newly designate both of the two adjustment colors on the spot, this is realized by executing the operation in step S41 twice. On the other hand, when it is desired to specify the color specified last time or last time and the color specified this time, it is executed by executing the operation of step S41 once. This kind of operation control is focused on the operability when it is necessary to repeat the color arrangement adjustment, such as when the area having the color to be adjusted overlaps simultaneously with multiple color areas. It may be an operation that requires operation.

  Subsequently, in step S52, the display colors of the various symbols displayed on the symbol display unit 33 are updated with the two adjustment target colors displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31. In the symbol display unit 33, symbols are arranged so that visual comparison with the two adjustment target colors displayed in the rectangular areas 31 a and 31 b of the adjustment color display unit 31 can be easily performed. The two adjustment colors displayed in the rectangular areas 31a and 31b and the comparison part (symbol groups 61, 62, 72, 74, 81, 83 in FIGS. 6 to 8 to be described later) are aligned in the vertical direction. Lined up.

  Here, an example of the symbol will be described with reference to FIGS.

  6 to 8 are diagrams showing examples of symbols according to the embodiment of the present invention.

  The symbols shown in FIG. 6 to FIG. 8 show specific examples of symbols for confirming the color perception effect, and each symbol is laid out so that a certain color perception effect can be easily judged visually. .

  The symbol examples shown in FIGS. 6 to 8 are merely examples, and symbols that make it easy to visually determine perceptual effects (for example, Mach effect, Herman grid effect, etc.) other than the color perceptual effects described below are employed. You can also

  FIG. 6 shows an example of a symbol for confirming the influence of the area effect that changes the appearance of the color even if the color is the same.

  In particular, the symbols 61 and 62 have a display area of a predetermined ratio (for example, about 2 to 5%) with respect to the display area of the two adjustment target colors displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31. Are symbols that display symbols of the same color as the color to be adjusted.

  However, if the display area of the symbols 61 and 62 is too small, human perception reacts only to lightness, so adjustment is made to ensure an area where the color can be perceived.

  FIG. 7 shows an example of a symbol for confirming the influence of the contrast effect in which the color appearance changes depending on the contrast of hue, saturation, and lightness.

  In particular, the symbols 72 and 74 have a display area of a predetermined ratio (for example, about 5 to 7%) with respect to the display area of the two adjustment target colors displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31. Are symbols that display symbols of the same color as the color to be adjusted.

  Further, as the background color symbols of the respective symbols 72 and 74, the symbols 71 and 73 of the other adjustment target colors that include the symbols 72 and 74 and are different from the adjustment target colors displayed by the symbols 72 and 74 are included. Are displayed in the same display area as the rectangular areas 31a and 31b of the adjustment color display unit 31.

  FIG. 8 shows an example of a symbol for confirming the influence of an assimilation phenomenon (von = Besolt effect) in which the color appearance changes depending on the relationship between hue, saturation, and lightness.

  In particular, the symbols 81 and 83 have a display area equivalent to the two adjustment target colors displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31, and display the same color symbols as the adjustment target colors as background colors. Symbol. In addition, at the front part, symbols 82 and 84 each having a color of another adjustment target color different from the adjustment target color displayed by the symbols 81 and 83 are formed by slit rectangular regions formed by equally spaced slits. indicate.

  Returning to the description of FIG.

  Subsequently, in step S53, the RGB values of the image data indicating the two colors to be adjusted are converted into HSV values (hue, saturation, brightness).

  In step S54, the setting value of the slider control group 35 of the adjustment color operation unit 32 is updated with the HSV value obtained by the conversion in step S53.

  Further, the description returns to FIG.

[Adjust color adjustment target color]
In the color adjustment window 22, the operator displays the two colors of adjustment colors displayed in the rectangular areas 31 a and 31 b of the adjustment color display unit 31 (the influence of the color perception effect is small) and the symbol display unit 33. In step S42, the slider control group 35 of the adjustment color operation unit 32 is operated to visually change the adjustment color displayed by the symbol (the influence of the color perception effect is large), and the HSV value is changed. Adjust the amount.

  The adjustment result by the operation of the slider control group 35 is reflected in the same color portion of the adjustment color display unit 31, the symbol display unit 33, and the image display window 21, and the display is updated.

  In this way, by comparing the same color portions of the adjusted color display unit 31 and the symbol display unit 33 whose display has been updated, it is confirmed whether the effect of the color perception effect is to be adjusted to a larger or smaller value. Can be used as a guideline for further adjustment.

  In the color arrangement adjustment of the present embodiment, since the perceptual effect of various colors caused by the overlap of colors and the difference in area in the actual image is simplified by the symbols, the color arrangement directly in the image Compared with the adjustment, it becomes easier to remove the influence of the color perception effect or to positively use the effect, and the degree of freedom of the color arrangement adjustment can be increased.

  For example, when correcting when one of the specified colors to be adjusted looks dull, simply increasing the saturation of that color may not solve the problem.

  On the other hand, in this embodiment, the adjustment color displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31 and the symbol are displayed as to whether the image is dull due to the contrast effect with the other adjustment target color selected. The adjustment colors displayed with various symbols on the display unit 33 can be confirmed by comparison. Then, the adjustment colors displayed in the rectangular areas 31a and 31b of the adjustment color display unit 31 have no problem as the target colors appear, while the adjustment colors displayed with the various symbols on the symbol display unit 33 appear dull. Then, it can be seen that there is an influence of saturation contrast, and it is possible to easily obtain the color intended by the operator by adjusting the saturation and brightness of the other adjustment color selected. .

  As described above, according to the present embodiment, since the color arrangement adjustment of any two colors in the image to be processed can be adjusted while checking the color perception effect, the operator can adjust the degree of freedom. High color adjustment can be easily and efficiently performed.

  In the above embodiment, the two colors in the image are designated as the adjustment target colors. However, the color arrangement adjustment is performed by designating three or more colors according to the purpose, purpose, and color composition in the image. It is good also as a structure to perform.
