  FIG. 3 is a part of the entire block diagram of FIG. 2 and summarizes the elements related to the image adjustment processing. The image adjustment process is a process for adjusting the saturation and color tone of the live view image LV and the reproduced image in accordance with an instruction from the photographer on the image adjustment screen described above. The image adjustment processing is mainly executed by the display control unit 110, the image processing unit 120, and the operation input unit 130.

  As described above, three modes of multi-color, color creator, and monochrome creator are prepared as image adjustment processing.

  The display control unit 110 creates an image adjustment screen corresponding to the selected mode, and superimposes the created image adjustment screen on the live view image or the like on the display unit 90 (the rear monitor 10 or the electronic viewfinder 12). indicate. In addition, when a predetermined instruction is input from the photographer on the image adjustment screen to the operation input unit 130, the display control unit 110 updates the image adjustment screen according to the content of the instruction, and is created by the image processing unit 120. An image in which the saturation is changed is displayed on the display unit 90.

  The display control unit 110 includes a color map creation unit 112, a color disc creation unit 114, and a monochrome disc creation unit 116 as functional units for creating an image adjustment screen.

  The color map creation unit 112 creates a color map that is a multi-color image adjustment screen and displays the color map on the display unit 90. Although details will be described later, the color map creation unit 112 uses the two-dimensional coordinates in which the hue corresponds to the angular direction and the saturation of each hue corresponds to the radial distance as the color map. Is displayed on the display unit 90. In addition, the color map creating unit 112 displays a polygon indicating the relative relationship of the saturation of each hue set by the operation input unit 130 on the color map.

  The color disk creation unit 114 creates a color disk that is an image adjustment screen for the color creator and causes the display unit 90 to display the color disk. The monochrome disk creation unit 116 creates a monochrome disk that is an image adjustment screen for a monochrome creator and causes the display unit 90 to display the monochrome disk.

The image processing unit 120 includes a multi-color processing unit 122, a color creator processing unit 124, and a monochrome creator processing unit 126 as functional units that adjust saturation and color tone on the image adjustment screen.
The multi-color processing unit 122 performs processing to change the saturation of an image having a hue specified on the image adjustment screen (color map) in the target image to a set saturation, and generates an image. To do. In the multi-color mode, hue portions not designated in the image are not affected.

  The color creator processing unit 124 performs processing for emphasizing the automatically adjusted color balance image to the color tone designated on the image adjustment screen (color disk). Further, the color creator processing unit 124 performs processing for changing the saturation of the image emphasized to the designated hue to the saturation set on the image adjustment screen (color disk), and generates an image. In the color creator mode, not only the saturation of an image having a specific hue but also the saturation of the entire image changes.

  The monochrome creator processing unit 126 performs monochrome conversion on the automatically adjusted color balance color image based on the hue and saturation specified on the image adjustment screen (monochrome disk) to generate a monochrome image. Even in the monochrome creator mode, monochrome conversion is performed on the entire color image, so that not only the saturation of the image having a specific hue but also the saturation of the entire image changes. Note that a device including the display control unit 110 and the operation input unit 130, or a device including the image processing unit 120 is referred to as an image adjustment device.

<Multi-color mode>
First, multi-color mode image adjustment processing will be described. In the multi-color mode, the saturation of a part having a specified hue in the image is adjusted to the set saturation. As described above, the hue portion not specified in the image is not affected.

  In multi-color mode, the image adjustment screen displays a color map that sets the saturation of the specified hue using two-dimensional coordinates in which the hue corresponds to the angular direction and the saturation of each hue corresponds to the radial distance. Let The image adjustment screen in the multi-color mode will be described with reference to FIGS.

  FIG. 4 is an example of an image adjustment screen displayed on the screen D1 of the display unit 90 so as to be superimposed on the live view image LV. The image adjustment screen includes a color map 200 and auxiliary marks (280, 282, 284, 286) arranged at the four corners of the color map 200.

  The auxiliary mark is auxiliary information for operation. The auxiliary mark 280 indicates that the front dial 20 is a means for adjusting the hue. The auxiliary mark 282 indicates that the rear dial 24 is a means for adjusting the saturation. The auxiliary mark 284 indicates the color of the designated hue. The auxiliary mark 286 indicates the set saturation value. ± 0 indicates that the current setting value of saturation is the default value.

  FIG. 5 is an enlarged view of the color map 200. The color map 200 of this example is an example in which the hue can be specified in 12 steps. Each hue corresponds to a direction at intervals of 30 °, that is, “0 o'clock to 11 o'clock” of the clock. In this example, the hue at 0 o'clock is "yellow", the hue at 1 o'clock is "yellow-orange", 2 o'clock is "red-orange", 3 o'clock is "red", 4 o'clock is "red purple", and 5 o'clock is " Purple, 6 o'clock "blue purple", 7 o'clock "blue", 8 o'clock hue "green blue", 9 o'clock "blue-green", 10 o'clock "green", 11 o'clock "yellowish green" " In the following description, for the sake of convenience, each hue is expressed as a pair with a corresponding direction as shown in FIG. 5 as “yellow (0 o'clock),..., Yellow green (11 o'clock)”. However, the characters “0 o'clock (yellow),..., 11:00 (yellow green)” may not be displayed on the screen.

  A regular dodecagonal hue ring 210 is arranged on the outer periphery of the color map 200. In the fan-shaped areas C <b> 0 to C <b> 11 at 30 ° intervals of the hue ring 210, the colors of the corresponding hues are displayed. For example, the area C0 is displayed with “yellow”, and the area C1 is displayed with “yellow-orange”. The color of the color wheel 210 may be displayed continuously without being divided into 12 colors.

  The color map 200 is provided with a control bar 230 that moves in the angle direction and designates the hue. The control bar 230 is composed of a row of stage number marks 232 indicating the setting position of saturation. In this example, an example in which the control bar 230 includes eight stage number marks 232 is shown. That is, the saturation can be set in 8 levels. The outermost step number mark 232a corresponds to the highest value of saturation, and the innermost step number mark 232b corresponds to the lowest value of saturation.

  In FIG. 5, the control bar 230 is in the 0 o'clock direction. The initial position of the control bar 230 is the direction of 0 o'clock. The control bar 230 is rotated in accordance with the rotation of the front dial 20. The rotation direction of the front dial 20 and the rotation direction of the control bar 230 are the same as viewed from the user.

  In the color map 200, color marks M0 to M11 are arranged at the currently set saturation positions of 12 hues. The color mark M0 indicates yellow (0 o'clock) saturation, and the color mark M1 indicates yellow-orange (1 o'clock). The twelve color marks M0 to M11 are collectively referred to as a color mark M.

  The color marks M0 to M11 are displayed in the corresponding hue color. Adjacent color marks are connected by a straight line to form one polygon as a whole. A polygon formed with the color mark M as a vertex and a straight line connecting adjacent color marks M as a side is referred to as a saturation graph 240. The saturation graph 240 shows the saturation balance of the entire hue.

  On the control bar 230, a point mark 250 is displayed at the current saturation setting position. The point mark 250 is displayed so as to be distinguishable from the stage number mark 232 and the color mark M. For example, the point mark 250 is displayed in a size larger than the stage number mark 232 and the color mark M. Further, the point mark 250 is displayed in a corresponding hue color.

  The point mark 250 moves the row of the stage number mark 232 according to the rotation of the rear dial 24. In the following description, when the rear dial 24 is rotated clockwise, the point mark 250 is moved in the inner circumferential direction and the saturation is set low. Conversely, when the rear dial 24 is rotated counterclockwise, It is assumed that the mark 250 moves in the outer peripheral direction and the saturation is set high.

  Further, the color map 200 includes a lower limit frame 220 indicating a lower limit (minimum value) of saturation that can be set, an upper limit frame 224 indicating an upper limit (maximum value) of saturation that can be set, and an initial value of saturation ( A neutral line 222 indicating a default value) is displayed. The lower limit frame 220, the upper limit frame 224, and the neutral line 222 are regular dodecagons whose centers are the same as the saturation graph 240.

  In FIG. 5, it is assumed that all the saturations are set to initial values. Therefore, all of the color marks M0 to M11 are located on the neutral line 222, and the saturation graph 240 overlaps the neutral line 222.

  FIG. 6 is an image adjustment screen showing an operation for setting the saturation without changing the hue. In FIG. 6 and subsequent figures, in order to avoid complication, the live view image LV is omitted from the screen, and only the color map 200 is shown. Further, the control bar 230 omits the step number mark 232 and is indicated by a thick broken line.

  When the rear dial 24 is rotated counterclockwise in the color map 200 of FIG. 4, the control bar 230 remains in the 0 o'clock direction as shown in the color map 200a of FIG. Moves to the outer peripheral side by the number of steps corresponding to the rotation angle of the rear dial 24. A color map 200a in FIG. 6 is an example in which the point mark 250 is moved by two stages. Thereby, the saturation of yellow (0 o'clock) is set higher by two steps, and the saturation of the yellow image is displayed higher by two steps in the image. A thin broken line indicates a neutral line 222.

  FIG. 7 is an image adjustment screen showing an operation for setting the saturation with the designated hue. When the front dial 20 is rotated clockwise in the color map 200a of FIG. 6, the control bar 230 moves clockwise according to the rotation angle of the front dial 20 as shown in the color map 200b of FIG. The color map 200b shows an example in which the control bar 230 has moved to red (3 o'clock). Thereby, red is designated as the hue.

  When the rear dial 24 is rotated clockwise, the point mark 250 is moved to the inner circumference side by the number of steps corresponding to the rotation angle of the rear dial 24 (color map 200c). A color map 200c shows an example of two-stage movement. Thereby, the saturation of red (3 o'clock) is set lower by two steps. The saturation of the red image is displayed two steps lower in the image.

  FIG. 8 is an image adjustment screen showing an operation in which the saturation is stopped at the upper limit or the lower limit. When the front dial 20 is rotated counterclockwise in the color map 200a of FIG. 6, the control bar 230 moves to yellowish green (11:00) as shown in the color map 200d of FIG. When the rear dial 24 is rotated in the clockwise direction, the point mark 250 moves to the inner peripheral side, but the point mark 250 stops at the lower limit frame 220 (color map 200e). Even if the rear dial 24 is rotated clockwise after the lower limit frame 220 is stopped, the operation is invalidated.

  Similarly, in the color map 200a of FIG. 6, when the rear dial 24 is rotated counterclockwise, the point mark 250 moves to the outer peripheral side, but the point mark 250 stops at the upper limit frame 224, and from the upper limit frame 224. It does not move outward (color map 200f).

  6 to 8 have described the method of adjusting the saturation of each hue (referred to as individual selection). On the image adjustment screen in the multi-color mode, the saturation of all hues can be adjusted together (referred to as all selection).

  Then, as a switching method from the individual selection image adjustment screen to the full selection image adjustment screen, a method by pressing a button (referred to as a full selection method 1), or a method of switching by moving the control bar 230 (all selection method 2 and 2) are prepared. Examples of the full selection method 1 and the full selection method 2 will be described below.

  FIG. 9 is a view for explaining an image adjustment screen for full selection according to the full selection method 1. A color map 200g in FIG. 9 is an individual selection image adjustment screen. As in FIG. 4, the auxiliary mark 284 indicates the color of the designated hue, and the auxiliary mark 286 indicates the set saturation (−2). When the INFO button 32 is pressed in the individually selected color map 200g, the color map 200h, which is an image selection screen for all selection, is switched. Since all the color marks M are switched to the point marks 250, the color marks M are displayed in the same size as the point marks 250.

  A display for distinguishing from individual selection is displayed on the image adjustment screen for all selections. For example, each side of the saturation graph 240 is displayed with a double line. An auxiliary mark 288 indicating all selections may be displayed at the same time. Note that the control bar 230 for designating the hue is not necessary on the image selection screen for all selections and is deleted.

  FIG. 10 is a diagram for explaining the transition of the image adjustment screen in the all selection method 1. When the rear dial 24 is rotated counterclockwise from the state of the color map 200h in FIG. 9, the saturation of each hue moves to the outer peripheral side by the number of steps corresponding to the rotation angle (color map 200i). The color map 200i is an example in which two stages are moved, and the saturation of all hues is set higher by two stages. The saturation graph 240 is enlarged while maintaining the saturation balance between hues.

  Further, when the INFO button 32 is pressed in the color map 200h, all selections are canceled, and the individual selection as shown in the color map 200j is returned, and the control bar 230 is displayed.

  FIG. 11 is a diagram for explaining an image adjustment screen for full selection according to the full selection method 2. The full selection method 2 is a method of switching from individual selection to full selection by moving the control bar 230 without using a button. Note that the operation of switching between individual selection and full selection by moving the control bar 230 is also referred to as a third operation. That is, when the third operation is performed, the operation input unit sets the saturation of all the hues with the rear dial 24, assuming that all the hues are designated.

  Specifically, the all-selection method 2 determines the switching area for switching between individual selection and all-selection between 0 to 360 ° of the color map 200, and moves the control bar 230 to the switching area, thereby selecting the individual selection. This is a method for switching all selections. Hereinafter, an operation example in a state where the switching area is set between 11:00 and 00:00 will be described.

  When the control bar 230 is positioned at 0:00 (color map 200k) and the front dial 20 is operated to move the control bar 230 in the 11 o'clock direction, the control bar 230 is fixed (still at 0:00). , Switch to full selection (color map 200l). If the rear dial 24 is rotated in this state, the saturation of each hue can be adjusted at once as in the all selection method 1. In the all selection method 2, as in the all selection method 1, the control bar 230 is deleted on the image adjustment screen.

  Further, when the front dial 20 is rotated counterclockwise as if the control bar 230 not displayed is moved in the 11 o'clock direction in the state of the color map 200l, all selection is canceled and individual selection is performed. Return to. Then, the control bar 230 is displayed on the image adjustment screen and moves in the 11 o'clock direction.

  Similarly, in the individual selection state, when the control bar 230 is operated from the state where the control bar 230 is located at 11:00 to move the control bar 230 in the 0 o'clock direction by the front dial 20, the selection is switched to full selection. When the front dial 20 is rotated clockwise again, all selection is canceled and the individual selection is restored. In this case, the control bar 230 is displayed and moves in the 0:00 direction.

  Moreover, you may provide the vertex for the switching area for all selections. In other words, the saturation graph 240 may be changed from a dodecagon to a dodecagon, and the vertex increased by one may be used as a switching area for all selections.

  Next, a process when the saturation of at least one hue has reached the upper limit in the fully selected state will be described. As described with reference to FIG. 8, in the individual selection, when the saturation reaches the upper limit or the lower limit, the subsequent operation is processed as invalid. In the full selection, it is possible to select two processes described below.

  In the first process of full selection, when the saturation of at least one hue reaches the upper limit, the saturation is not changed in all hues even if an operation of increasing the saturation with the rear dial 24 is performed thereafter. . That is, the saturation that has not reached the upper limit is not changed. Of course, when an operation for decreasing the saturation is performed, the saturation of all the hues is decreased according to the operation.

  The same applies when the saturation of one hue reaches the lower limit. That is, in a state where the saturation of at least one hue has reached the lower limit, the saturation is not changed in all hues even if an operation of lowering the saturation with the rear dial 24 is performed thereafter.

  In the second process of full selection, when an operation of increasing the saturation with the rear dial 24 is performed in a state where the saturation of at least one hue has reached the upper limit, the saturation of the hue that has not reached the upper limit is set. , Raised in response to operation. Similarly, when an operation for decreasing the saturation with the rear dial 24 is performed in a state where the saturation of at least one hue has reached the lower limit, the saturation of the hue that has not reached the lower limit is decreased according to the operation. It is done. FIG. 12 illustrates a specific example of the second process of full selection in a state where the saturation of one hue has reached the upper limit.

  FIG. 12 is a diagram for explaining the second process of full selection. In the saturation graph 241a, the saturation of blue purple (6 o'clock) has reached the upper limit, and the saturation of red purple (4 o'clock) has reached the lower limit (color map 201a). When the rear dial 24 is operated to increase the saturation by one step, the saturation of the blue-purple (6 o'clock) is stopped at the upper limit in the saturation graph 241b, and the saturation of other hues is increased by one step, and yellow (0 o'clock) ) Reaches the upper limit (color map 201b).

  Furthermore, when the rear dial 24 is operated to increase the saturation by one step, the saturation of blue-violet (6 o'clock) and yellow (0 o'clock) is stopped at the upper limit in the saturation graph 241c, and the saturation of other hues is stopped. Goes up one step and blue (7 o'clock) reaches the upper limit (color map 201c).

  Further, when the operation of increasing the saturation with the rear dial 24 is performed, only the saturation of the hue that has not reached the upper limit is increased one step at a time (color map 201d, color map 201e). When the saturation of all hues reaches the upper limit (saturation graph 241f, color map 201f), the subsequent operation of increasing the saturation of the rear dial 24 is treated as invalid.

  Next, when the operation of lowering the saturation with the rear dial 24 is performed on the color map 201f, the saturation of all the hues is not decreased, but the operation of increasing the saturation with the color maps 201a to 201e is performed. Saturation is lowered to retroactively change the order. That is, when the rear dial 24 is operated to lower the saturation by one step, the state returns from the saturation graph 241f of the color map 201f to the saturation graph 241e of the color map 201e. Similarly, in accordance with the operation of lowering the saturation by one step with the rear dial 24, the saturation is lowered at the stage of color map 201e → color map 201d → color map 201c → color map 201b → color map 201a. As a result, it is possible to realize the overall saturation adjustment in line with the operator's intention.

  Next, the reset operation will be described. FIG. 13 is a diagram illustrating a state in which a reset operation has been performed. The color map 200m is an image adjustment screen in which the saturation of yellow-green (11 o'clock) and yellow (0 o'clock) is adjusted. When a reset operation (pressing the OK button 34) is performed, the saturation of all hues returns to the initial position, and the color marks M0 to M11 return to the position of the neutral line 222 (color map 200n). The saturation graph 240 coincides with the neutral line 222. The control bar 230 moves at 0:00. In the reset operation, the color marks M0 to M11 may return to the preset line instead of the position of the neutral line 222. Preset lines are, for example, saturation settings that increase the saturation near blue and capture the sky vividly, or saturation settings that increase the overall saturation and capture the flowers vividly. Is the condition. The preset line may be set as an initial value by the manufacturer as in the ** mode, or may be registered as a favorite setting by the user.

  Until now, the example which uses the front dial 20 as an input means which designates a hue was demonstrated. As described above, in the multi-color mode, only the saturation of the image having the designated hue is changed. That is, the multi-color mode is image adjustment for changing the saturation of a specific image. Therefore, it can be said that it is more direct to specify the image currently displayed on the screen. In the following, an example in which the hue for which saturation is set is directly input from an image will be described.

  FIG. 14 is a diagram illustrating an example in which a hue is designated from a display image using the touch panel 10a. On the left side of the screen on which the color map 200p is displayed, a live view image LV, a reproduced image, and the like are displayed. When a touch operation is performed on the subject whose saturation is to be changed on the screen D, the touch position is specified by the operation input unit 130. The hue of the object displayed at the specified touch position is detected, and a hue close to the detected hue of the object is selected from the 12 colors. Details will be described with reference to FIG. A color map 200q in which the control bar 230 is moved to a hue close to the touched subject is displayed. Thereafter, the saturation is set by rotating the rear dial 24 as before. Note that a cursor 260 for indicating the position of the touched subject may be displayed at the place where the touch operation on the screen is performed.

  Further, means for specifying a subject in a live view image LV, a reproduced image, or the like is not limited to the touch panel 10a. For example, the subject may be specified on the screen by the XY direction button 33 and the hue of the specified subject may be detected. A hue close to the detected hue of the subject is selected from the 12 hues.

  FIG. 15 is an image adjustment screen for changing the size of the color mark M in accordance with the saturation. In the example up to FIG. 14, the size of the color mark M is a constant example regardless of the saturation. An example in which the size of the color mark M is indicated by the size according to the saturation, that is, the size according to the radial distance will be described with reference to FIG. Thereby, not only the position of the color mark M in the radial direction but also the size of the color mark M can be grasped.

  As shown in the color map 202a, when the color mark M is at the position of the upper limit frame 224, that is, when the saturation is the upper limit, the size of the color mark M (including the point mark 250) is maximized. For example, the color mark M0 and the color mark M8 are the maximum size.

  When the color mark M is the neutral line 222, that is, when the saturation is the initial value, the size of the color mark M is set to an intermediate size. In the color map 202a, the color mark M5 and the color mark M7 are intermediate sizes. When the color mark M is in the position of the lower limit frame 220, that is, when the saturation is the lower limit, the size of the color mark M is minimized. In the color map 202a, the color mark M6 is the minimum size.

  Further, as shown in the color map 202a and the color map 202c, the size of the color mark M is selected so that adjacent color marks M do not overlap at all positions from the upper limit to the lower limit.

  In addition, although the example of a screen was shown by individual selection in FIG. 15, it is applicable also to all selection. According to the multi-color mode described above, it is possible to change only the saturation of a desired hue without changing the saturation of another hue, so that it is possible to create a free color.

  In the multi-color mode, as the image adjustment screen, the saturation of the specified hue is set by the color map 200 of the two-dimensional coordinates in which the hue corresponds to the angular direction and the saturation of each hue corresponds to the radial distance. Therefore, even a novice user can intuitively adjust the saturation of the desired hue. In addition, since the polygonal saturation graph 240 is displayed on the color map 200, the saturation balance of each hue can be seen at a glance by the shape of the saturation graph 240.

  In the multi-color mode, the hue and saturation are set by rotating the two dials, respectively. Therefore, the operation while looking into the electronic viewfinder 12 is easy.

  In the multi-color mode, since all selections are provided in addition to individual selection, it is possible not only to change the saturation of a specific hue, but also to change the saturation of the entire hue collectively. As a result, it is possible to adjust the saturation of a specific hue up and down after the saturation of the entire image is first adjusted to an appropriate position in the overall selection.

  And to switch to full selection, both the button method and the dial method are prepared so that they can be selected according to the usage environment. If the dial method is used, the switching operation while looking into the electronic viewfinder 12 can be easily performed. In addition, since the color mark is sized according to the level of saturation (distance in the radial direction), the level of saturation is also indicated by the size of the color mark. Since the size of the color mark matches the level of saturation, it is possible to prevent the user from making a mistake in the direction of operation.

<Picture mode>
So far, the image adjustment processing in the multi-color mode in the picture mode has been described. In the following, a description will be given by comparing the three image adjustment screens of the multi-color mode, the monochrome creator, and the color creator.

  Note that the image adjustment screens of the multi-color mode, the monochrome creator, and the color creator are also referred to as a first image adjustment screen, a second image adjustment screen, and a third image adjustment screen. The color map creation unit 112, the monochrome disc creation unit 116, and the color disc creation unit 114 are also referred to as a first display control unit, a second display control unit, and a third display control unit.

  FIG. 16 is a diagram for explaining the procedure of image adjustment in the multi-color mode. Since the description regarding the color map 200 in the multi-color mode has been described, the description is omitted. A screen D1 of the display unit 90 is a screen of the live view image LV normally displayed in the shooting mode. On this screen, when the picture mode dial 40 is set to CI which is the position of the multi-color mode and the PICT button 30 is pressed, the multi-color mode is set.

  The color map 200 is superimposed and displayed on the right side of the live view image LV (screen D2). As the color map 203, a hue circle 210, a control bar 230, and a saturation graph 240 are displayed. The screen D2 is an individual selection screen.

  From the individual selection (screen D2), when the INFO button 32 is pressed, all selection (screen D3) is entered. This is the all selection method 1 described above. In the color map 203a, each side of the saturation graph 240 is displayed with a double line, indicating that it has been switched to full selection.

  When the operation of moving the control bar 230 from 0 o'clock to 11 o'clock is performed by the front dial 20 from the individual selection state (screen D2), the state becomes the full selection state (screen D4). This is the all selection method 2 described above. Also in the color map 203b, each side of the saturation graph 240 is displayed with a double line, indicating that it has been switched to full selection.

  As described above, the color map creation unit 112 (first display control unit) is an image adjustment screen that adjusts the saturation of the hue specified in the image. The first image adjustment screen for setting the hue for adjusting the saturation and the saturation to be adjusted is generated on the two-dimensional coordinates in which the saturation of the image is associated with the radial distance.

  FIG. 17 is a diagram for explaining image adjustment in the monochrome creator mode. In the monochrome creator mode, the same effect as when a color filter is attached to the lens unit 3 is realized by digital image processing. An example of the effect by a color filter is given. For example, when a red filter is attached to the lens unit 3, light having a wavelength near red is transmitted through the filter and other wavelengths are absorbed by the filter, so that a monochrome image in which red is strongly reflected can be obtained. In other words, when the red filter is installed, the red brightness is strong and the complementary color intensity is suppressed, so in a monochrome image the red part is bright (white) and the complementary color part dark (black). In the monochrome creator mode, such an image is generated by image processing in accordance with an instruction from the user.

  The monochrome creator mode is a process for shifting an image color balance to a specified filter color and converting an image weighted with a set filter density into a monochrome image. For this reason, in the monochrome creator mode, unlike the multi-color mode, not only a specific hue portion of the image but also the entire image is changed. The same applies to the color creator mode described later.

  When the picture mode dial 40 is set to M which is the position of the monochrome mode on the normal screen (screen D10) on which the live view image LV is displayed in color, the normal live view display is displayed when the PICT button 30 is pressed. Switch to monochrome creator mode.

  In the monochrome creator mode, the live view image LV is displayed in monochrome, and the monochrome disk 400a is superimposed on the right side of the live view image LV (screen D11). The monochrome disk 400a is an image adjustment screen in the monochrome creator mode.

  FIG. 18 is an enlarged view of the monochrome disk 400. In the monochrome disk 400, the filter color is designated in the angular direction, and the filter density is set in the radial direction. The hue and saturation of the color map 200 correspond to the filter color and filter density of the monochrome disk 400.

  The monochrome disk 400 is provided with a hue ring 410, a neutral area 420, a control bar 430, and a density ring 440. The hue ring 410 is a scale indicating the direction of the filter color. In the hue ring 410, changing hues are continuously displayed. In the color map 200, the hue ring 210 has a polygonal shape, but in the monochrome disk 400, the hue ring 410 is displayed in a circular shape. This is because the monochrome saturation graph 240 displayed on the color map 200 does not exist on the monochrome disk 400.

  The neutral area 420 is an area that is set in a state where no color filter is attached to the lens unit 3. The control bar 430 designates a filter color in the angular direction, and rotates according to the rotation of the front dial 20. The density ring 440 indicates the level of the filter density depending on the size of the diameter, and the diameter changes according to the rotation of the rear dial 24. In this example, it is assumed that the filter density increases as the diameter of the density ring 440 increases, and the filter density decreases as the diameter of the density ring 440 decreases.

  The monochrome disk 400a on the screen D11 is in a state where the control bar 430 is in the direction of 4 o'clock and the density ring 440 is the maximum diameter. When the filter color in the 4 o'clock direction is red, the live view image LV is image-processed and displayed as if the red filter was attached to the lens unit 3. The red part of the subject is displayed as bright as possible in a monochrome image. If the flower of the live view image LV is red, the brightness of the flower portion is displayed higher on the screen D11 than on the screen D10.

  When the rear dial 24 is rotated in the minus direction on the monochrome disk 400a on the screen D11, as shown in the monochrome disk 400b on the screen D12, the diameter of the density ring 440 is reduced and the filter density is set low. On the screen D12, the flower portion of the live view image LV is displayed darkly.

  Further, when the rear dial 24 is further rotated in the minus direction on the monochrome disk 400b on the screen D12, the diameter of the density ring 440 becomes smaller and the filter density is set lower as shown on the monochrome disk 400c on the screen D13. The On the screen D13, the flower portion of the live view image LV becomes darker than the screen D12.

  When the front dial 20 is rotated in the minus direction on the screen D11 and the control bar 430 is moved to 10:00, the screen is switched to the screen D14. Here, since “10 o'clock” is at a position rotated by 180 ° from “4 o'clock”, the filter color of “10 o'clock” is assumed to be a complementary color of green. Since green, which is a complementary color of red, is designated as the filter color, the luminance of red decreases as shown in the monochrome disk 400d of the screen D14, and the flower portion of the live view image LV becomes darker than the screen D11.

  When the rear dial 24 is rotated in the minus direction on the screen D14, the diameter of the density ring 440 is reduced and the filter density is lowered as shown in the monochrome disk 400e on the screen D15. The flower portion of the view image LV becomes brighter than the screen D14.

  When the rear dial 24 is further rotated in the minus direction on the screen D15, the filter density decreases as shown in the monochrome disk 400f of the screen D16, and the flower portion of the live view image LV becomes brighter than the screen D15.

  On the screen D12, when the front dial 20 is rotated in the minus direction, the screen shifts to the screen D15. Similarly, when the front dial 20 is rotated in the minus direction on the screen D13, the screen shifts to the screen D16.

  When the control bar 430 is set to the 0 o'clock position, that is, in the neutral area 420, the color filter is not attached to the lens, so that the density cannot be adjusted.

  As described above, the monochrome disk creation unit 116 (second display control unit) is an image adjustment screen for adjusting a monochrome coefficient for converting a color image into a monochrome image according to the set filter color and filter density. Then, a monochrome disk 400 (second image adjustment screen) for setting the filter color and the filter density on the two-dimensional coordinates in which the filter color corresponds to the angle direction and the filter density corresponds to the radial distance is generated. .

  As described above, in the monochrome creator mode, it is possible to acquire an image equivalent to that when a filter is mounted without mounting an actual filter. By displaying the monochrome disk 400 as the image adjustment screen, it is possible to easily specify the filter color and set the filter density.

  FIG. 19 is a diagram for explaining image adjustment in the color creator mode. The color creator mode is a process of correcting the white balance to a specified hue and adjusting the image to a set value of saturation. In the color creator mode, the color disc 500 is displayed as an image adjustment screen.

  When the picture mode dial 40 is set to the color mode position CII on the normal screen (screen D20) on which the live view image LV is displayed and the PICT button 30 is pressed, the normal live view display is colored. Switch to creator mode.

  In the color creator mode, the color disc 500a is superimposed and displayed on the right side of the live view image LV (screen D21).

  FIG. 20 is an enlarged view of the color disk 500. Similar to the color map 200, the color disc 500 also shows hue in the angular direction, and shows saturation in the length in the radial direction.

  The color disk 500 is provided with a hue ring 510, a neutral area 520, a cursor 540, and a neutral line 550.

  The hue ring 510 is a scale for indicating the angular direction of the hue, and is equivalent to the hue ring 410 of the monochrome disk 400. The neutral area 520 is also equivalent to the neutral area 420 of the monochrome disc 400. A cursor 540 is used to specify a hue and set a saturation. The angle direction of the cursor 540 changes according to the rotation of the front dial 20, and the position in the radial direction changes according to the rotation of the rear dial 24. In this example, it is assumed that the saturation is higher as the cursor 540 is positioned on the outer peripheral side, and the saturation is lower as it is positioned on the inner peripheral side.

  Returning to FIG. In the color disk 500a of the screen D21, the cursor 540 has an angular direction of 4 o'clock and a radial position on the outermost periphery. As in the example of FIG. 17, when the 4 o'clock direction is red, white balance is emphasized and corrected in the red direction, and image processing is performed so that the saturation is maximized. The live view image LV is displayed with high saturation and strong redness.

  When the rear dial 24 is rotated in the minus direction on the screen D21, the cursor 540 is moved to the inner peripheral side as shown in the color disc 500b on the screen D22, and the saturation is set low. The live view image LV is displayed with low saturation and strong redness.

  When the front dial 20 is rotated on the screen D21 and the cursor 540 is moved in the 10 o'clock direction, as shown in the color disc 500c on the screen D23, if the 10 o'clock direction is green, the white balance is in the green direction. Emphasis is corrected. The live view image LV is highly saturated and green is displayed strongly.

  When the front dial 20 is rotated on the screen D23 and the cursor 540 is moved to the inner circumference side in the direction of 10 o'clock, the saturation is set low as in the color disc 500d shown in the screen D24. The live view image LV is displayed with low saturation and strong green.

  When the front dial 20 is rotated on the screen D22 and the cursor 540 is moved in the 10 o'clock direction, the screen shifts to the screen D24.

  Further, when the cursor 540 is adjusted to the direction of 0 o'clock and the cursor 540 is adjusted along the radial direction of the neutral area 520 by rotating the rear dial 24, the white balance does not emphasize and correct a specific hue. Only saturation can be adjusted.

  With the color creator mode, the entire image can be emphasized to a specified color and vividness can be adjusted.

  As described above, the color disc creation unit 114 (third display control unit) sets the hue for emphasizing and correcting the color balance of the image and the saturation of the entire image for which the color balance is emphasized and corrected, respectively. This is an image adjustment screen for instructing the color adjustment of the image, and the hue and saturation are set by moving the cursor on the two-dimensional coordinates with the hue corresponding to the angle direction and the saturation corresponding to the radial distance. The color disk 500 (third image adjustment screen) to be generated is generated.

  In the picture mode, it has been described that “hue and saturation” and “filter color and filter density” are operated with the “front dial 20 and rear dial 24”, but the present invention is not limited to this. For example, instead of the “front dial 20 and rear dial 24”, an operation ring provided on the lens barrel may be used as the operation means. As described above, three types of image adjustment screens corresponding to the respective adjustment methods were prepared. Since three types of image adjustment screens that are easy to operate are prepared, even a novice user can take a favorite image.

<Picture mode control processing>
Next, control processing in the picture mode will be described. The following processing is mainly executed by the camera control unit 100.

  FIG. 21 is a flowchart for explaining the processing procedure of the entire imaging apparatus 1. It is assumed that the imaging device 1 is set to the shooting mode. The camera control unit 100 displays the image (live view image LV) captured by the imaging unit 62 on the rear monitor 10 or the electronic viewfinder 12 (step S10). The camera control unit 100 performs UI (user interface) processing while displaying the live view image LV (step S12).

  FIG. 22 is a subroutine showing a procedure of UI (user interface) processing. The CPU 140 reads the setting conditions for the previously executed picture mode from the storage memory 82 (step S30). The CPU 140 selects a process depending on which mode of the picture mode is currently set (step S32). When the normal live view screen is switched to the picture mode, the CPU 140 selects a mode according to the position of the picture mode dial 40.

  If the current picture mode is the multi-color mode, the CPU 140 performs multi-color processing (step S34). If the current picture mode is the color creator mode, the CPU 140 performs color creator processing (step S36). When the current picture mode is the monochrome creator mode, the CPU 140 performs a monochrome creator process (step S38). Details of step S34 to step S38 will be described later.

  CPU 140 determines whether or not a mode change operation has been performed based on a notification from operation input unit 130 (step S40). When CPU 140 determines that a mode change operation has been performed (step S40 YES), it returns to step S30. When CPU 140 determines that the mode change operation has not been performed (NO in step S40), the process proceeds to step S14 in FIG.

  Returning to FIG. Based on the notification from the operation input unit 130, the CPU 140 determines whether a power-off operation has been performed by pressing the power button 26 (step S14). When the CPU 140 determines that the power-off operation has not been performed (NO in step S14), the CPU 140 determines whether or not a shooting operation has been performed by pressing the shutter button 22 (step S16).

  When CPU 140 determines that a shooting operation has been performed (YES in step S16), it executes a shooting process (step S18) and returns to step S10. If CPU 140 determines that no shooting operation has been performed (NO in step S16), it returns to step S10.

  When CPU 140 determines that a power-off operation has been performed (YES in step S14), it executes an end process (step S20) and ends the process.

  Returning to FIG. 22, the multi-color processing in step S34 will be described. FIG. 23 is a subroutine showing the procedure of multicolor processing.

  The CPU 140 determines whether or not a multi-color calling operation has been performed by pressing the PICT button 30 (step S50). The CPU 140 performs processing according to the previous setting according to the setting condition of the previous picture mode read out in step S30 (step S52).

  When the previous setting is individual selection, the CPU 140 displays an individual selection image adjustment screen (color map) (step S54). Specifically, the color map 200 displayed last last time is displayed. For example, the CPU 140 displays the color map 200 shown in FIG.

  When the previous setting is the all selection method 1, the CPU 140 displays an image adjustment screen for the all selection method 1 such as the color map 200h in FIG. 9 (step S56). Specifically, the color map 200 of the all selection method 1 displayed last time is displayed.

  If the previous setting was the all selection method 2, the CPU 140 displays an image adjustment screen for the all selection method 2 such as the color map 200l in FIG. 11 (step S58). Similar to step S56, the color map 200 of the all selection method 2 displayed last last time is displayed.

  FIG. 24 is a diagram showing the relationship among individual selection, all selection method 1 and all selection method 2. As described above, the individual selection and the all selection method 1 are switched by button operation. Individual selection and all selection method 2 are switched by dial operation.

  Next, the CPU 140 determines whether a button operation has been performed (step S60). When CPU 140 determines that a button operation has been performed (YES in step S60), it performs a button operation process (step S62).

  FIG. 25 is a subroutine showing the procedure of button operation processing. In the following, only processing by the operation of the INFO button 32 in the button operation will be described. Other button operations not related to the picture mode are omitted.

  The CPU 140 determines whether the INFO button 32 has been operated (step S100). When CPU 140 determines that INFO button 32 has been operated (YES in step S100), CPU 140 performs processing in accordance with the current setting (step S102). If the CPU 140 determines that the INFO button 32 is not operated (step S100 NO), the CPU 140 proceeds to step S64 in FIG.

  If the current setting is the all selection method 2, the CPU 140 ignores the operation of the INFO button 32 and returns to step S64 in FIG. If the current setting is the all selection method 1, the CPU 140 changes to individual selection (step S104).

  When the current setting is individual selection, the CPU 140 determines whether there is one or more hues whose saturation reaches the upper limit (step S106). If the CPU 140 determines that there is no hue at which the saturation reaches the upper limit (NO in step S106), the CPU 140 changes to the all selection method 1 (step S110) and proceeds to step S112.

  If the CPU 140 determines that there is one or more hues whose saturation reaches the upper limit (YES in step S106), the CPU 140 determines whether there is one or more hues whose saturation reaches the lower limit (step S108). The CPU 140 determines that no hue has reached the lower limit of saturation (NO in step S108), and changes to the all selection method 1 (step S110).

  CPU140 performs the display process accompanying a change (step S112). The CPU 140 instructs the display control unit 110 to change the color map 200. The color map creation unit 112 of the display control unit 110 creates a color map 200 corresponding to the change, and the display control unit 110 displays the created color map 200 on the display unit 90. After step S112, the CPU 140 proceeds to step S68.

  If the CPU 140 determines that there is one or more hues whose saturation reaches the lower limit (step S108 YES), the CPU 140 returns to step S64 without changing to the all selection method 1. This is because when there is a saturation that has reached the upper limit and the lower limit, respectively, the changing method is not adapted to the saturation.

  Returning to FIG. When CPU 140 determines that no button operation has been performed (NO in step S60), the process proceeds to step S64. CPU 140 determines whether a dial operation has been performed (step S64). When CPU 140 determines that a dial operation has been performed (YES in step S64), it performs a dial operation process (step S66). When CPU 140 determines that the dial operation has not been performed (NO in step S64), the process proceeds to step S68.

  FIG. 26 is a subroutine showing the procedure of dial operation processing. CPU 140 determines whether the operation is an operation of rear dial 24 (step S120). When CPU 140 determines that the operation is not an operation of rear dial 24 (NO in step S120), the process proceeds to step S140. When CPU 140 determines that the operation is an operation of rear dial 24 (step S120 YES), CPU 140 selects a process according to the current setting (step S122).

  When the current setting is individual selection, the CPU 140 changes the saturation set with the designated hue in accordance with the rotation direction and rotation angle of the rear dial 24 (step S124).

  Further, when the current setting is the all selection methods 1 and 2, the CPU 140 determines whether the operation of the rear dial 24 is in the direction of increasing the saturation (step S126). When the CPU 140 determines whether the operation of the rear dial 24 is to increase the saturation (YES in step S126), the CPU 140 determines whether there is a hue whose saturation reaches the upper limit (step S128). If the CPU 140 determines that there is a hue whose saturation reaches the upper limit (YES in step S128), the operation of the rear dial 24 is invalidated and the process proceeds to step S140.

  When the CPU 140 determines that there is no hue whose saturation reaches the upper limit (NO in step S128), the CPU 140 changes the saturation of all hues to a higher value (step S130), and proceeds to step S136.

  If the CPU 140 determines that the operation of the rear dial 24 is not in the direction of increasing the saturation (NO in step S126), the CPU 140 determines whether there is a hue whose saturation reaches the lower limit (step S132). CPU 140 determines that there is a hue whose saturation has reached the lower limit (YES in step S132), invalidates the operation of rear dial 24, and proceeds to step S140.

  If the CPU 140 determines that there is no hue whose saturation reaches the lower limit (NO in step S132), the CPU 140 changes the saturation of all the hues to be low (step S134), and proceeds to step S136.

  Then, the CPU 140 performs color mark size setting processing (step S136). FIG. 27 is a subroutine showing the procedure of color mark size setting processing. The color map creation unit 112 of the display control unit 110 changes the display size of the color mark according to the radial position of the color mark M. FIG. 15 described above shows an example in which the size of the color mark is continuously increased according to the radial direction, but FIG. 27 shows an example of processing for changing the display size of the color mark M with reference to the neutral line 222. explain. The following color mark M includes a point mark 250.

  The CPU 140 determines whether the color mark M has been changed to a value inside the neutral line 222, that is, a value lower than the initial value (step S160). If the CPU 140 determines that the color mark has been changed to the inner side of the neutral line 222 (YES in step S160), the CPU 140 sets the size of the color mark M to a smaller size than usual according to the changed saturation (step S162).

  If the CPU 140 determines that the color mark M has not been changed to the inside of the neutral line 222 (NO in step S160), the CPU 140 sets the size of the color mark M to the normal size (step S164).

  The CPU 140 determines whether the size setting has been completed for the color marks M of all the changed hues (step S166). This is the case where all selections are set. In the case of individual selection, step S166 is always YES. If the CPU 140 determines that the size setting has not been completed for the color marks M of all the changed hues (NO in step S166), the CPU 140 switches to the next color mark M (step S168) and returns to step S160. If the CPU 140 determines that the size setting process has been performed for the color marks M of all the changed hues (YES in step S166), the process proceeds to step S138 in FIG.

  After step S136, the CPU 140 instructs a display process corresponding to the saturation change (step S138). In response to an instruction from the CPU 140, the multi-color processing unit 122 changes the saturation of the designated hue in the image processing. Then, the multi-color processing unit 122 generates a live view image LV or the like with the saturation changed for the designated hue. In addition, the color map creation unit 112 generates a color map 200 corresponding to the change. The display control unit 110 displays the color map 200 corresponding to the live view image LV whose saturation has been changed.

  CPU 140 determines whether the operation is an operation of front dial 20 (step S140). If the CPU 140 determines that the operation is not an operation of the front dial 20 (NO in step S140), the process proceeds to step S68 in FIG.

  When CPU 140 determines that the operation is an operation of front dial 20 (step S140 YES), CPU 140 selects a process corresponding to the current setting (step S142). When the current setting is individual selection, the CPU 140 determines whether the operation content is an operation of the all selection method 2 (step S144). The operation to change to the all selection method 2 is the operation described in FIG.

  When the CPU 140 determines that the operation content is not the operation of the all selection method 2 (NO in step S144), the CPU 140 changes the hue according to the operation direction and the rotation angle of the front dial 20 (step S146).

  When CPU 140 determines that the operation content is an operation of all selection method 2 (step S144 YES), CPU 140 changes the setting from individual selection to all selection method 2 (step S148).

  Further, when the current setting is the all selection method 2, the CPU 140 determines whether the operation content is an operation for canceling all the selections (step S150). When CPU 140 determines that the operation content is an operation for canceling all selection (YES in step S150), CPU 140 changes the setting from all selection method 2 to individual selection (step S152).

  After step S146, step S148, and step S152, the CPU 140 performs display processing corresponding to a change in hue or the like (step S154). Since the display process is equivalent to step S138, description thereof is omitted. In response to an instruction from the CPU 140, the color map creation unit 112 generates a color map 200 in which the designated hue is changed, or a color map 200 in which individual selection and all selection are switched.

  When CPU 140 determines that the operation content is not an operation for canceling all selection method 2 (NO in step S150), the process returns to FIG. Further, even when the current setting is the all selection method 1, the CPU 140 invalidates the operation of the front dial 20 and proceeds to step S68 in FIG.

  Returning to FIG. CPU 140 determines whether a touch panel operation has been performed (step S68). When CPU 140 determines that the touch panel operation has not been performed (NO in step S68), the process proceeds to step S72. When CPU 140 determines that a touch panel operation has been performed (YES in step S68), it performs a touch panel operation process (step S70).

  FIG. 28 is a subroutine showing a procedure of touch panel operation processing. This is the processing of the operation described in FIG. CPU 140 determines whether individual selection is set (step S180). Designation of hue by touch panel operation is valid only for individual selection.

  If the CPU 140 determines that the individual selection is set (step S180 YES), the CPU 140 determines whether the touch location is the live view image LV (step S182). When the CPU 140 determines that the touch location is the live view image LV (step S182 YES), the multi-color processing unit 122 of the image processing unit 120 extracts the image of the touch location and specifies the hue of the touch location. The multi-color processing unit 122 selects a hue closest to the hue of the identified touch location from the 12 colors of the color map 200.

  The CPU 140 moves the point mark 250 to the hue at the touch location (step S184). The color map creation unit 112 creates a color map 200 in which the control bar 230 is moved in the angular direction corresponding to the hue selected by the multi-color processing unit 122.

  After the process of step S184, the CPU 140 returns to FIG. If the CPU 140 determines that the individual selection is not set (NO in step S180) or the touch location is not the live view image LV (step S182 NO), the process proceeds to step S72 in FIG.

  Returning to FIG. The CPU 140 determines whether a reset operation has been performed by pressing the OK button 34 (step S72). When determining that the reset operation has been performed (YES in step S72), the CPU 140 performs a reset process for returning the saturation of all colors to the initial values (step S74). As described with reference to FIG. 13, the color map 200 is displayed in which the saturation of all hues returns to the neutral line 222 and the control bar 230 also returns to 0:00. When CPU 140 determines that a reset operation has not been performed (NO in step S72), the process proceeds to step S76.

  The CPU 140 determines whether an operation for closing the multi-color mode has been performed (step S76). The operation for closing the multi-color mode is, for example, pressing of the PICT button 30. If CPU 140 determines that the operation for closing the multi-color mode has not been performed (NO in step S76), it returns to step S54.

  If CPU 140 determines that an operation to close the multi-color mode has been performed (YES in step S76). The final setting state of the multi-color mode, the position of the control bar 230, and the like are stored in the storage memory 82 (step S78), the multi-color mode is terminated, and the process returns to step S40 in FIG.

<Image mode image processing>
The image processing of the multi-color mode, the monochrome creator, and the color creator will be described in order.

  FIG. 29 is a flowchart showing the procedure of multicolor processing in the multicolor mode. The multi-color processing unit 122 of the image processing unit 120 mainly executes the following multi-color processing. By using the multi-color mode, the user can adjust the saturation of multiple colors individually and create free colors.

  The multi-color processing unit 122 acquires the saturation value of each hue from the storage memory 82 (step S200). The saturation value of each hue is, for example, a saturation value stored in the storage memory 82 as a value set in the previous multi-color mode or an initial value (default value) when not set. .

  The multi-color processing unit 122 sets 12 to the counter n corresponding to each hue (step S202). Reference numeral 12 denotes the number of hues that can be selected in the color map 200, which is 12 colors as in FIG.

  Assume that a predetermined adjustment has been made in the color map 200. The multi-color processing unit 122 acquires the saturation level of COLOR (n) set in the color map 200 (step S204). COLOR (n) means the nth hue. For example, COLOR (12) is yellowish green, which is the hue at 11:00 in FIG. Further, as shown in the color map 200 of FIG. 5, when the saturation is 8 levels, the acquired saturation level is any one of −3, −2, −1, 0, +1, +2, +3, and +4. .

  The multi-color processing unit 122 performs correction processing for the saturation value of COLOR (n) (step S206). The multi-color processing unit 122 corrects the saturation value acquired in step S200 based on the saturation level of COLOR (n) acquired in step S204.

  The multicolor processing unit 122 sets the counter n ← n−1 (step S208). This is for switching the hue to be corrected. The multicolor processing unit 122 determines whether n> 0 is satisfied (step S210).

  If the multi-color processing unit 122 determines that n> 0 (step S210 YES), the process returns to step S204. The multi-color processing unit 122 repeats until all colors are corrected. If the multi-color processing unit 122 determines that n> 0 is not satisfied (NO in step S210), the multi-color processing unit 122 generates an image based on the saturation after the correction, assuming that the correction of all colors has been completed. Is output (step S212).

  Note that the image to be subjected to multicolor processing may be either a live view image LV or a reproduced image. Further, the live view image LV is always displayed during shooting and when the color map 200 is displayed. The live view image LV is converted into an image file and stored in the external memory 84 when shooting is executed.

  FIG. 30 is a flowchart showing the procedure of monochrome creator processing in the monochrome creator mode. As described above, in the monochrome creator mode, an image similar to that when the color filter is attached to the lens unit 3 is generated by image processing. The monochrome creator processing unit 126 of the image processing unit 120 mainly executes monochrome creator processing.

  The monochrome creator processing unit 126 acquires information set on the monochrome disk 400 (step S220). The monochrome creator processing unit 126 acquires filter color and filter density information set on the monochrome disk 400. The set filter color is called a selection color, and the complementary color of the set filter color is called a non-selection color.

  The monochrome creator processing unit 126 calculates a monochrome coefficient (referred to as a monochrome conversion coefficient) (step S222). The monochrome creator processing unit 126 determines a monochrome conversion coefficient from the acquired setting information. Specifically, the monochrome creator processing unit 126 calculates the monochrome coefficient by weighting the standard monochrome coefficient so that the selected color is increased and the non-selected color is decreased. Also, the monochrome creator processing unit 126 calculates the monochrome coefficient by changing the weighting according to the set filter density.

  Also, the monochrome creator processing unit 126 acquires a coefficient predetermined for each setting information such as filter color and filter density with reference to a table stored in the storage memory 82, and uses the acquired coefficient as a standard monochrome coefficient. May be weighted.

  The monochrome creator processing unit 126 generates color image data (standard image) subjected to WB (white balance) adjustment from the imaging data (step S224). The monochrome creator processing unit 126 performs a weighting operation on the standard image according to the monochrome coefficient to form a monochrome image (step S226). The monochrome creator processing unit 126 outputs a monochrome image (step S228).

  The image to be subjected to the monochrome creator process may be either a live view image LV or a reproduced image. The live view image LV is always displayed during shooting and when the monochrome disk 400 is displayed. The live view image LV is converted into an image file and stored in the external memory 84 when shooting is executed.

  FIG. 31 is a flowchart showing the procedure of color creator processing in the color creator mode. The color creator processing unit 124 of the image processing unit 120 mainly performs color creator processing. The color creator mode is a mode in which the entire image is emphasized to a specified color and the vividness can be adjusted.

  The color creator processing unit 124 acquires information set on the color disc 500 (step S240). The color creator processing unit 124 acquires information on hue and saturation set in the color disc 500.

The color creator processing unit 124 performs standard image processing (step S242). The color creator processing unit 124 generates color image data that has been subjected to WB adjustment from the imaging data.

  The color creator processing unit 124 performs a color correction process (step S244). The color creator processing unit 124 emphasizes and corrects WB in the set hue direction, but does not rotate the hue. The color creator processing unit 124 increases or decreases the saturation according to the set saturation. That is, the color creator processing unit 124 weights the set hue direction and corrects the entire saturation according to the set saturation.

  The color creator processing unit 124 generates and outputs a color-corrected image (step S246). The image to be subjected to color creator processing may be either a live view image LV or a reproduced image. The live view image LV is always displayed during shooting and when the color disc 500 is displayed. The live view image LV is converted into an image file and stored in the external memory 84 when shooting is executed.

<Color scale display>
So far, an example has been described in which hue and saturation or filter color and filter density are expressed in polar coordinates as an image adjustment screen, but the two-dimensional display is not limited to polar coordinates. FIG. 32 is a diagram showing an image adjustment screen in which hue and saturation are represented by XY orthogonal coordinates. A screen D30 in FIG. 32 is a screen on which the color creator graph 600 is superimposed and displayed on the live view image LV (not shown). The color creator graph 600 is an image adjustment screen in the color creator mode.

  The color creator graph 600 includes a color palette 610 and a monochrome palette 620. The color palette 610 corresponds to the color disc 500, and the left-right direction of the color palette 610 corresponds to hue, and the up-down direction corresponds to saturation. The monochrome palette 620 corresponds to the neutral area 520 described with reference to FIG.

  The color palette 610 is colored and displayed in order in the horizontal direction corresponding to the hue. For example, in order from the left end to the right, yellow, yellow-orange, red-orange, red, magenta, purple, blue-violet, blue, green including blue, blue-green, green, yellow-green (C0, ... , C11) is displayed. The hue may be displayed so as to change continuously, instead of being divided by area as in the screen D30.

  Then, a cursor 630 that can be moved vertically and horizontally is displayed on the color palette 610. The hue is set at the horizontal position of the cursor 630, and the saturation is set at the vertical position of the cursor 630.

  The monochrome palette 620 is an area for adjusting only the saturation without changing the color balance of the subject. The saturation is set according to the vertical position of the cursor 630 on the monochrome palette 620.

  Further, the cursor 630 may be moved by the set of the front dial 20 and the rear dial 24 as before, but may be directly performed by the XY direction button 33.

  A screen D31 in FIG. 32 is a screen on which a multi-color graph 650 is superimposed and displayed on a live view image LV (not shown). The multi-color graph 650 is a multi-color image adjustment screen. Similar to the color palette 610, the multi-color graph 650 is colored and displayed in order in the horizontal direction corresponding to the hue (C0,..., C11). Note that the hue may be displayed so as to change continuously without being divided by area.

  In the multi-color graph 650, the upper and lower sides correspond to saturation. On the multi-color graph 650, the hue is designated at the position in the left-right direction, and the saturation of the hue designated at the top-bottom position is set. A marker 680 is displayed at the saturation position set for each hue, and the markers 680 are connected by a straight line. A neutral line 685 indicated by a broken horizontal line is a line indicating an initial value (default value) of saturation. The neutral line 685 is equivalent to the neutral line 222 described in FIG. The hue finger and saturation are set by moving the cursor 670. The cursor 670 is displayed in a size larger than the marker 680.

  Further, the movement operation of the cursor 670 may be performed by the set of the front dial 20 and the rear dial 24 as before, but may be directly performed by the XY direction button 33.

  Even in the image adjustment screen based on the XY coordinates described above, the user can intuitively grasp the operation procedure similarly to the image adjustment screen based on the polar coordinates, so that even a user who does not particularly have knowledge of image adjustment can easily perform the operation.

Hue and saturation when the degree reaches the upper limit If the hue reaches exists to each of the picture adjustment screens are not set for the entire selection.

Moreover, you may provide the vertex for the switching area for all selections. That is, the color map 200 may be changed from a 12-sided shape to a 13-sided shape, and the vertex increased by one may be used as a switching area for all selections.

When the front dial 20 is rotated on the screen D11 and the control bar 430 is moved to 10:00, the screen is switched to the screen D14. Here, since “10 o'clock” is at a position rotated by 180 ° from “4 o'clock”, the filter color of “10 o'clock” is assumed to be the complementary green color of red. Since green, which is a complementary color of red, is designated as the filter color, the luminance of red decreases and the flower portion of the live view image LV becomes darker than the screen D11 as shown in the monochrome disk 400d of the screen D14.

Further, when the front dial 20 is rotated on the screen D12, the screen shifts to the screen D15. Similarly, when the front dial 20 is rotated on the screen D13, the screen shifts to the screen D16.

When the rear dial 24 is rotated on the screen D23 and the cursor 540 is moved toward the inner periphery in the direction of 10 o'clock, the saturation is set low as in the color disc 500d shown in the screen D24. The live view image LV is displayed with low saturation and strong green.
