  FIG. 3 is a functional block diagram relating to the color adjustment processing of the imaging apparatus 1. The control unit 110, the image area designation unit 120, and the color adjustment screen creation unit 130 are functional units realized by the CPU 100 that has read the control program.

  The control unit 110 controls the entire functional unit related to image adjustment processing. The image area designation unit 120 designates a predetermined area of the displayed image in response to an instruction from the operation unit 10 (for example, the touch panel 44). The color adjustment screen creation unit 130 is a screen for performing color adjustment of an image, and creates a color adjustment screen for adjusting attribute values of each hue. Hue attribute values include saturation and lightness. An example of adjusting the saturation of a specified hue will be described below. The touch panel determines the touch area or the representative coordinates such as the center of gravity of the touch area, but various area determinations may be performed in accordance with each specification. The area around the touched point may be taken into account, or the touched area itself may be used, or the target area may be displayed in a frame so that the user can confirm it. Here, it is written that the hue is determined from the designated area, but the designated area may be determined in consideration of the hue. This can be realized by determining the change point of the color, contrast and brightness of the surrounding image around the touch position.

  FIG. 4 is a display example of the color adjustment screen. A color adjustment screen 400 is displayed at the lower right of the live view image LV displayed on the rear display unit 42. The color adjustment screen 400 is configured to indicate the saturation of each hue by two-dimensional coordinates in which the hue corresponds to the angular direction and the saturation of each hue corresponds to the radial distance. The subject in FIG. 4 is a flower, the hue of the petal f is mainly Or (orange), the hue of the petal g is mainly Y (yellow), and the hue of the leaf h is mainly GY (yellowish green). And The button t is a button for setting the entire live view image LV as a designated area.

  FIG. 5 is an enlarged view of the color adjustment screen 400 of FIG. The hues divided into 12 are arranged discretely at equal angular intervals in a circumferential shape. The number of hues is arbitrary and may be 12 or more. FIG. 5 shows an example in which 12 hues are arranged at positions corresponding to 0 o'clock, 1 o'clock.

Y (yellow) at 0 o'clock, Or (orange) at 1 o'clock, R (red) at 2 o'clock, RP (red purple) at 3 o'clock, P (purple) at 4 o'clock PB (blue purple) at 5 o'clock, B (blue) at 6 o'clock, Cb (green-blue) at 7 o'clock, C (cyan) at 8 o'clock, GC (blue-green) at 9 o'clock ) G (green) is arranged at the 10 o'clock position, and GY (yellowish green) is arranged at the 11 o'clock position. The hue name (Y, Or, etc.) is surrounded by a frame, and the inside of the frame is drawn with a color corresponding to the hue.
Many such hue circles are known, but of course, it is not necessary to limit to hue, and it may be considered as a simple primary color such as RGB. If one of the plurality of colors is selected and selected, the features of the present invention can be realized.

  A line segment 412 extending radially from the center O toward the outer periphery is an axis indicating the strength (darkness) of the set saturation. A mark 414 on the line segment 412 indicates a set value of saturation. As the mark 414 is closer to the center O, the saturation is set lighter, and as the mark 414 goes to the outer periphery, the saturation is set darker. A neutral line 416 indicated by a broken line indicates a standard position of saturation in each hue. When the saturation is not changed, each mark 414 is displayed at the position of the neutral line 416.

  The hue is selected according to the rotation operation of the front dial 12. For example, according to the right rotation operation of the front dial 12, the selected hue is switched in the order of Y → Or → R.

  Further, when selecting a hue, not only one hue is selected from all the hues by operating the front dial 12, but the hue of the designated image (hereinafter referred to as a related color) is selected from the color adjustment screen 400. It is also possible to select one hue by operating the front dial 12 after the display.

  In any case, after the hue is selected, the saturation of the selected hue is changed by operating the rear dial 16. It is also possible to change the saturation of all hues at once. According to the color adjustment screen 400, the saturation balance between hues can be confirmed at a glance.

  Then, the color adjustment screen creation unit 130 creates the color adjustment screen 400 so that the hue selected by operating the front dial 12 is identified among the hues. In addition, when an image is designated, the color adjustment screen creation unit 130 creates a color adjustment screen 400 that distinguishes the related colors of the designated image. Furthermore, when there are a plurality of related colors, the color adjustment screen creation unit 130 may create a color adjustment screen 400 that distinguishes the hues of the related colors according to the strength of the degree of association. The display of related colors will be described in detail with reference to FIG.

  Then, when the saturation is changed by operating the rear dial 16, the color adjustment screen creation unit 130 creates the color adjustment screen 400 corresponding to the changed saturation. The display of “→” and “Vivid” below the color adjustment screen 400 in FIG. 4 indicates that the saturation is increased by the operation of the rear dial 16 in the counterclockwise direction.

  The contents of the functional blocks of the color adjustment process shown in FIG. 3 will be briefly described. Image data is input to the image generation unit 240 from the imaging unit 230, the image memory 260, or the external device 300.

  The image generation unit 240 performs predetermined image processing on the image data and outputs the image data to the display control unit 250. The display control unit 250 creates an image in which the color adjustment screen 400 is superimposed on the image data, and displays the image on either the rear display unit 42 or the EVF 46 on the image display unit 40.

  The control unit 110 notifies the image region designation unit 120 of the position of the image designated by the operation unit 10. The image area designating unit 120 sets a predetermined range of the image centered on the designated position as the designated area. The hue determination unit 270 divides the designated area into areas, specifies the hue of each divided area, and determines the hue related to the designated area based on the number of hues in each divided area. The determined hue is a related color. The hue determination unit 270 notifies the color adjustment screen creation unit 130 of the determined hue.

  The color adjustment screen creation unit 130 creates a color adjustment screen 400 showing the determined hue. The display control unit 250 generates an image in which the color adjustment screen 400 is superimposed on the image data, and outputs the generated image to the image display unit 40. The image display unit 40 displays an image on which the color adjustment screen 400 is superimposed.

  The control unit 110 identifies the hue according to the operation of the front dial 12 and sets the saturation value in the identified hue according to the operation of the rear dial 16. The control unit 110 instructs the image generation unit 240 to change the hue and saturation to be changed. The image generation unit 240 performs color adjustment processing according to the changed hue and saturation, and generates an image.

  FIG. 6 is a flowchart for explaining the procedure of color adjustment processing by the color adjustment apparatus. The control unit 110 detects the pressing of the power button 18 and turns on the power of the imaging device 1 (step S10). The control unit 110 switches the operation mode according to the operation of the mode button 22, and inputs image data from any of the imaging unit 230, the image memory 260, or the external device 300 to the image generation unit 240 (step S12).

  In the shooting mode, image data of a live view image is input from the imaging unit 230 to the image generation unit 240. In the reproduction mode, image data of a captured image is read from the image memory 260 and input to the image generation unit 240. In the external device mode, the image data of the external device 300 is input to the image generation unit 240 via the external device IF 280. As described above, the external device 300 is an imaging device such as a microscope or an endoscope, for example.

  In the following, it is assumed that the operation mode is set to the shooting mode and the image data of the live view image LV from the imaging unit 230 is the image generation unit 240. Further, assuming that the PICT button 20 is pressed, the control unit 110 causes the color adjustment screen 400 to be superimposed and displayed on the live view image as illustrated in FIG.

  The image generation unit 240 performs predetermined image processing such as interpolation processing on the input image data. Among them, the image generation unit 240 performs image color adjustment processing with the saturation value set for each hue. If no adjustment operation is performed on the color adjustment screen 400 after the power is turned on, the image generation unit 240 applies the previous saturation value stored in the storage memory 210. The image generation unit 240 applies a standard value (default value) when the storage memory 210 does not have a previous saturation value.

  The display control unit 250 superimposes the color adjustment screen 400 on the live view image processed by the image generation unit 240, and displays the image with the color adjustment screen 400 on the image display unit 40 (step S14, FIG. 4).

  The control unit 110 determines whether an area has been designated for the displayed live view image LV (step S16). When the image display unit 40 is the rear display unit 42, the control unit 110 detects the area designation and position by the touch operation and the touch position by the photographer on the touch panel 44. FIG. 8 is a diagram showing a state where an area is designated by a photographer. Specifically, FIG. 8 shows a state where the photographer's finger is touched to the live view image LV displayed on the rear display unit 42. When the image display unit 40 is the EVF 46, the control unit 110 detects the region designation and the position by operating the XY direction button 26 and the OK button by the photographer.

  If control unit 110 determines that no area has been designated (NO in step S16), control proceeds to step S22. When determining that the area has been designated (step S16 YES), the controller 110 performs a hue determination process (step S18).

  FIG. 7 is a subroutine for explaining the procedure of the hue determination process. The image area designating unit 120 extracts a predetermined range (for example, 100 × 100 pixels) of the image centered on the area designated position as the designated area. In FIG. 8, for the sake of explanation, the range of the designated area 450 is indicated by a black frame, but the range of the designated area 450 may not be displayed visually. When the button t described with reference to FIG. 4 is pressed, the image area specifying unit 120 sets the entire live view image LV as the specified area. The image area designating unit 120 may designate a range continuously surrounded by touched fingers as the designated area.

  The hue determination unit 270 inputs the image of the designated area output from the image area designation unit 120 (step S40). The hue determination unit 270 divides the image of the designated area into a predetermined number of areas (step S42).

  FIG. 9 is a diagram showing a state where the designated area 450 designated in FIG. 8 is divided into a predetermined number of areas. The upper part of the designated region 450 is roughly a leaf h, the center is a petal f, and the lower part is a petal g. The hue determination unit 270 divides the designated area 450 into, for example, a total of 25 areas of 5 × 5. Numbers 1 to 25 in FIG. 9 indicate numbers of the divided areas.

  The hue determination unit 270 measures the color of each divided area (step S44) and determines the hue of each divided area (step S46). When the image data of each pixel is in the HSV format, the hue determination unit 270 calculates, for example, average H from the HSV data of the divided area, and sets the average H as H of the divided area.

  FIG. 10A is an example of the HS plane of the HSV color space, and is a diagram illustrating a hue (H) range. The circumferential direction is hue (H), and the radial direction is saturation (S). As shown in FIG. 10A, H is defined by a counterclockwise angle with the downward y-axis being 0 ° (starting point). Y, Or... GY means the same hue as the symbols described in FIG. FIG. 10B is a table showing the H range of each hue shown in FIG. 10A.

In addition, when the image data of each pixel is in the RGB format, the hue determination unit 270 calculates H of the image data of each pixel from the following formula to obtain H of the divided area.
The maximum value of R, G, B is MAX, the minimum value is MIN,
When MIN = MAX, H = 0
When MIN = B, H = (60 × (G−R) / (MAX−MIN)) + 60
When MIN = R, H = (60 × (B−G) / (MAX−MIN)) + 180
When MIN = G, H = (60 × (R−B) / (MAX−MIN)) + 300

  The hue determination unit 270 calculates the H of each divided area, and determines the hue of each divided area from the calculated H of each divided area with reference to the table of FIG. 10B. The table of FIG. 10B is stored in the storage memory 210. FIG. 11A is a table showing the H value and hue of each divided area shown in FIG. For example, the hue determination unit 270 determines that the hue is GY from H = 182 in the divided area No1. The right column of FIG. 11A is the determined hue name.

  The hue determination unit 270 counts the number of divided areas for each hue (step S48). FIG. 11B is a table of the number of divided areas determined for each hue. FIG. 11B is a table in which the hues in the right column of FIG. 11A are summed. For example, the number of divided areas of GY (yellowish green) is eight.

  The hue determination unit 270 determines a hue with a count number ≧ k (step S50). The count number is the number of divided areas for each hue. Further, k is a threshold value for excluding hues with a low appearance frequency and focusing only on the main hues. For example, k = 6.

  The hue determination unit 270 determines that GY (yellowish green), Y (yellow), and Or (orange) are the hues (related colors) of the designated region on the condition that, for example, k = 6 and the number of divided areas is 6 or more. To do. The hue determination unit 270 outputs GY, Y, and Or as the hues of the designated area to the color adjustment screen creation unit 130 (step S52).

  The color adjustment screen creation unit 130 creates a color adjustment screen 400 that shows GY, Y, and Or determined as related colors separately from other hues. The display control unit 250 displays the created color adjustment screen 400 on the image display unit 40 (step S20). FIG. 12 is an example of a color adjustment screen 400a or the like in which related colors are displayed separately. In the color adjustment screen 400a, only the frames of the related colors GY, Y, and Or are colored and displayed, and the frames of the hues other than the related colors are not colored. In the color adjustment screen 400a, the related color marks 414a, 414b, and 414c are displayed in color, and the mark 414d other than the related color is displayed in no color (monochrome).

  Returning to FIG. The controller 110 determines whether a color adjustment operation has been performed (step S22). In the color adjustment operation, the hue is selected with the front dial 12 and the saturation is set with the rear dial 16. If the controller 110 determines that the color adjustment operation has not been performed (NO in step S22), the control unit 110 proceeds to step S28. In the operation of selecting a hue on the color adjustment screen using the front dial 12, the control unit 110 performs operation control so that only a related color is selected by skipping hues other than the related color. Also good.

  When the control unit 110 determines that the color adjustment operation has been performed (YES in step S22), the color adjustment screen creation unit 130 changes the color adjustment screen 400 according to the color adjustment operation, and the display control unit 250 is changed. The color adjustment screen 400 is displayed (step S24). The color adjustment screen 400b in FIG. 12 shows a state in which, for example, the marks 414b and 414c are moved in the outer peripheral direction, and the saturation of Y and Or is set to be deep.

  Further, when there are a plurality of determined hues, that is, when there are a plurality of related colors, the color adjustment screen creation unit 130 displays the color adjustment screen 400 so that the hues can be distinguished according to the number of corresponding areas. You may create it. For example, the color adjustment screen 400c shown in FIG. 12 is an example in which Or having the largest number of areas is displayed in a square frame so as to be distinguished from others. The color adjustment screen creation unit 130 may display a color adjustment screen indicating the number of areas corresponding to the hue name.

  The image generation unit 240 generates an image on which a predetermined color adjustment process has been performed in accordance with the color adjustment operation, and the display control unit 250 displays the generated image (step S26). FIG. 13 is a diagram schematically illustrating a change in color tone (saturation) of a live view image by color adjustment processing. The image shown in FIG. 13 is a part of the live view image LV of FIG. The hue of the subject petal f is mainly Or (orange), the hue of the petal g is mainly Y (yellow), and the hue of the leaf h is mainly GY (yellowish green).

  The upper part of FIG. 13 is a diagram illustrating a change in color tone when the saturation of Y (yellow) is adjusted. The live view image LV (0) at the center of each stage is an image when GY, Y, and Or are all standard values. The live view image LV (+ Y) is an image when the saturation of Y is set high. A petal g having Y as the main hue is expressed vividly. The live view image LV (−Y) is an image when the saturation of Y is set low. Petal g is expressed gently. Petals f and leaves h with a small Y component are less affected by Y saturation adjustment.

  The middle part of FIG. 13 is a diagram illustrating a change in color tone when the saturation of Or (orange) is adjusted. The live view image LV (+ Or) is an image when the saturation of Or is set high, and the petals f whose hue is the main color of Or are vividly expressed. The live view image LV (-Or) is an image when the saturation of Or is set low, and the petals f whose main color is Or are gently expressed. The petals g and leaves h are less affected by the change in Y saturation.

  The lower part of FIG. 13 is a diagram showing a change in color tone when the saturation of GY (yellowish green), Y (yellow), and Or (orange) is adjusted. The live view image LV (+ GY / Y / Or) is an image when the saturation of GY / Y / Or is set high. The entire screen is expressed vividly. The live view image LV (-GY / Y / Or) is an image when the saturation of GY / Y / Or is set low. The entire screen is expressed gently.

  Returning to FIG. The control unit 110 determines whether the power is turned off by pressing the power button 18 (step S28). When controller 110 determines that the power is not turned off (NO in step S28), it returns to step S12. When determining that the power is turned off (YES in step S28), the control unit 110 performs an off process (step S30), and ends the operation of the imaging device 1. The control unit 110 may store the saturation value of each hue changed on the color adjustment screen 400 in the storage memory 210 as the off process.

<Effect>
The impression of the image varies greatly depending on the color, but in a color adjustment device for adjusting this color, it is necessary to specify a color such as a hue to be adjusted on the adjustment screen. However, although many hue names are presented on the adjustment screen, it is often impossible to determine which hue corresponds to the color of the subject to be changed. In particular, it is not easy to accurately select a corresponding hue name for a low-luminance subject or a subject in which a plurality of colors overlap. Especially for beginners, it is often difficult to find the hue name to be adjusted. According to the above embodiment, the hue of the subject is determined simply by specifying the subject to be adjusted, so even a beginner can easily select an accurate hue and adjust the saturation to a desired state. it can.
-In addition, since the subject to be adjusted can be specified by a touch operation, even a beginner can operate it easily.
-Since a certain range including the touch position is set as the hue determination area, the accuracy of the touch position is not required.
Since the designated area is divided and the related color is determined based on the number of hues in each divided area, it is possible to efficiently exclude noise-like colors that are dispersed throughout the designated area.
In addition, since the hues with the number of areas equal to or less than the predetermined number are not included in the related colors, only hues having a high influence on the subject can be presented.
-Since a GUI similar to the hue circle is displayed as the color adjustment screen, the operation for changing the saturation is intuitive and easy to understand.
