The lens control unit 21 drives the drive unit 24a based on the position information of the zoom lens detected by the position detection unit 25a, and controls the position of the zoom lens in the lens system 26 so that a zoom image with a desired magnification is obtained. . The lens control unit 21 drives the drive unit 24b based on the position information of the focus adjustment lens detected by the position detection unit 25b, and controls the position of the focus adjustment lens so that the subject is in focus. .

The lens control unit 21 performs data communication with the signal processing / control unit 1 of the camera body 10 through the communication unit 28 and the communication unit 14 of the camera body 10.
On the other hand, the camera body 10 includes a signal processing / control unit (camera control unit) 1 including a computer. The signal processing / control unit 1 includes an imaging device 2, an eye sensor 3, a recording unit 4, an operation determination unit 6, a display unit (rear monitor) 8 as a second display unit, a touch panel 8a, The operation unit 9 is connected to the communication units 12 and 14.

  As shown in FIG. 1B, the eyepiece sensor 3 is provided on the back surface of the apparatus, and determines whether or not the user is looking into the viewfinder with respect to the eyepiece 30 for EVF. The eyepiece sensor 3 detects that the user's eye is approaching the EVF eyepiece 30.

The recording unit 4 includes, for example, a Flash ROM, a RAM, or a memory card, for example. The Flash ROM is a rewritable non-volatile memory, and stores in advance a program for overall camera operations such as imaging, reproduction, operation, and display. The Flash ROM also stores user settings. In addition, image data may be stored in the Flash ROM, and the image data may be read from the Flash ROM and played back and displayed.
In addition, the Flash ROM has an image quality adjustment program for adjusting the image quality for imaging the subject. This image quality adjustment program is generated by a signal processing / control unit 1 composed of a computer by imaging a subject with an imaging unit including an imaging device 2 and a lens system 26, and performing image processing on an image signal output from the imaging device 2. A live view image is displayed on an EVF eyepiece 30 and a direct-view display 8 having a liquid crystal display (hereinafter referred to as LCD) (hereinafter, the display 8 is referred to as rear LCD 8), and The display for image quality adjustment related to imaging is displayed superimposed on the live view display, and the display mode for image quality adjustment is adjusted for the eyepiece 30 for the EVF and the rear LCD 8 respectively.
That is, the EVF eyepiece 30 and the rear LCD 8 have completely different appearances even when the same image is displayed. Since the EVF eyepiece 30 is used while looking into the user, it is less susceptible to ambient light. Further, the user can concentrate his / her consciousness on the live view image by looking into the eyepiece 30 for EVF. Therefore, the operability is improved by displaying the operation screen in a mode suitable for each of the display on the eyepiece 30 for EVF and the display on the rear LCD 8. As a result, the live view superimposed display can be changed in the display mode between the EVF eyepiece 30 and the rear LCD 8. The display mode is, for example, brightness, the thickness or color of the drawing line, and the transparency.
Further, the Flash ROM stores data for adjusting image quality when an object to be described later is imaged.

The RAM of the recording unit 4 is a volatile memory and is used as a temporary storage of image data and a work area for image processing. Image data (JPEG etc.) and moving image data after shooting are recorded on the memory card of the recording unit 4. Further, image data is stored in the memory card, and the image data is read from the memory card and reproduced and displayed.
Further, the RAM of the recording unit 4 is used for developing data read from a Flash ROM or the like.
The image quality adjustment data includes, for example, tone curve adjustment data for adjusting the brightness of image data, adjustment data for adjusting white balance, adjustment data for adjusting exposure, and color adjustment. Adjustment data for performing the above. The image quality adjustment data is represented by a two-dimensional graph, for example.

  FIG. 2 is a schematic diagram of tone curve adjustment data T. FIG. The tone curve adjustment data T indicates the relationship of the brightness (gradation) output to the brightness (gradation) input. The tone curve adjustment data T has a plurality of adjustment data T1, T2,..., Tn. These adjustment data T1, T2,..., Tn have different brightness input / output relationships (gamma values), and adjustment data having a larger or smaller gamma value than the straight line (γ = 1) adjustment data T1. It has become. These adjustment data T2,..., Tn are set so as to be brighter or darker by a predetermined brightness than the adjustment data T1. When adjusting the brightness of the image data, one of the plurality of adjustment data T1, T2,..., Tn is selected.

FIGS. 3A and 3B and FIGS. 4A and 4B show the difference in image quality of the image data by changing the tone curve adjustment data T. FIG. FIGS. 3A and 3B show an example in which the dark area in the image data is made darker. FIG. 3A shows tone curve adjustment data T for adjusting the dark area D to be darker. FIG. 5B shows image data Sd in which a dark region is adjusted to be darker by the same tone curve.
FIGS. 4A and 4B show an example in which a bright area in image data is brightened. FIG. 4A shows tone curve adjustment data T for adjusting the bright area L to be brighter. FIG. 5B shows image data Sl in which a bright area is adjusted brighter by the tone curve.
As shown in FIG. 1B, the tone curve adjustment display is displayed superimposed on the live view image. The user can change the adjustment data T while confirming both the live view image and the tone curve without changing the line of sight by operating the adjustment dial, the cross key, the touch panel, or the like in the operation unit 9.
At this time, consideration is given so that the adjustment display does not hinder the appearance of the live view image. Specifically, the brightness, line thickness, color, transparency, etc. of the adjustment display are optimally adjusted and displayed. However, the optimal display mode is not the same between the EVF eyepiece 30 and the rear LCD 8.
In other words, when shooting with the EVF eyepiece 30 that is easily influenced by shooting without being influenced by the environment, an adjustment display that is superimposed to prioritize display of the live view image over shooting with the rear LCD 8. Adjust in a direction that is inconspicuous. For example, for a surface display that draws the drawing line thinly in gray with low saturation and hides the live view, adjustment is made such as increasing the transparency.
Here, it is also effective to analyze the live view image and draw it with a line of the same color as the subject color, or to adjust the transparency and brightness according to the brightness of the subject.
In the case of shooting with the rear LCD 8, the influence of the surrounding environment is increased, contrary to the EVF eyepiece 30, and the adjustment is made in the direction of increasing the visibility of the adjustment display. For example, the transparency is lowered or the drawing line is drawn with a thick and high saturation color.

FIGS. 5A to 5D show changes in the luminance level of the image data when adjusted by the tone curve adjustment data T. FIG. FIG. 5A shows a change in luminance level of the image data So before adjustment.
FIG. 6B shows a change in luminance level of the image data Sd obtained by adjusting the dark region D to be darker with the tone curve adjustment data T as shown in FIGS. 3A and 3B with respect to the image data before adjustment. . The brightness level of the image data Sd corresponding to the dark region D is further lowered.
FIG. 4C shows a change in luminance level of the image data S1 obtained by adjusting the bright area D with the tone curve adjustment data T as shown in FIGS. 4A and 4B with respect to the image data before adjustment. . The brightness level of the image data Sd corresponding to the bright area L is further increased.
FIG. 4D shows changes in each luminance level in the case of exposure correction as a comparison of (a) to (c). In the case of exposure compensation, the brightness level changes uniformly.

  FIG. 6 is a schematic diagram of the adjustment data W for adjusting the white balance. In this white balance, the mixing ratio of the colors of amber (A), blue (B), green (G), and magenta (M) is adjusted. For example, at the center position of the ABGM color, each of the ABGM colors is mixed at an equal mixing ratio.

FIG. 7 is a schematic diagram of adjustment data E for adjusting the exposure. In this exposure adjustment, the relationship between the aperture AV and the shutter speed SS is adjusted. For example, by changing the aperture 26c, it is possible to change the static expression of a moving subject by controlling the amount of background blur or changing the shutter speed. Overexposure and underexposure can be adjusted freely while viewing the live view.
The image quality adjustment data is not limited to tone curve adjustment data, white balance adjustment data, exposure adjustment data, and color adjustment adjustment data.

  The operation determination unit 6 determines operation states of various operation units 9 that are manually operated by the user. The operation unit 9 includes, for example, a release button, a moving image button, a mode dial, a selection key, a power button, and the like. The release button has a 1st release switch and a 2nd release switch. The 1st release switch is turned on when the user presses the release button halfway. When the 1st release switch is turned on, the signal processing / control unit 1 performs a shooting preparation operation such as AF processing. The 2nd release switch is turned on when the user fully presses the release button. When the 2nd release switch is turned on, the signal processing / control section 1 performs an exposure operation for still image shooting.

The moving image button is an operation member for instructing the start or end of moving image shooting. When the moving image button is pressed by the user, the moving image shooting process is started. Further, when the moving image button is pressed during the moving image shooting process, the moving image shooting process is ended.
The mode dial is an operation member for selecting shooting settings of the imaging apparatus. In the present embodiment, for example, a still image shooting mode and a moving image shooting mode can be selected as shooting settings of the imaging apparatus. The still image shooting mode is a shooting setting for shooting a still image. The moving image shooting mode is a shooting setting for shooting a moving image.
The selection key is an operation member for selecting or determining an item on the menu screen, for example. When the selection key is operated by the user, an item is selected or determined on the menu screen.
The power button is an operation member for turning on or off the power of the imaging apparatus. When the power button is operated by the user, the apparatus is activated and becomes operable. If the power button is operated while the apparatus is activated, the apparatus enters a power saving standby state.

The rear LCD 8 is provided on the rear surface of the apparatus, and has, for example, an LCD driving unit. The rear LCD 8 displays images for live view display and still images and moving images recorded in the recording unit 4. On the display screen of the rear LCD 8, a touch panel 8a is integrally provided. The so-called rear LCD 8 is a rear LCD 8 with a touch panel.
The touch panel 8a detects contact (touch) of a user's finger or the like, and outputs a contact signal including coordinates indicating the touch position. The signal processing / control unit 1 drives the touch panel 8a, inputs a contact signal from the touch panel 8a, detects a user's touch on the rear LCD 8 with a touch panel from the contact signal, and executes a process according to the touch. .
The touch panel operation is optimal as a two-dimensional input device typified by the above-described tone curve, white balance, and exposure adjustment, and is particularly effective at the time of shooting on the rear LCD 8 with a touch panel. When shooting on the rear LCD 8 with a touch panel, the adjustment screen should be clearly displayed in order to improve the input operability by the touch panel 8a.
On the other hand, in the case of shooting with the EVF eyepiece 30, it is difficult for the user to see the display on the rear LCD 8, and thus the operability of the touch panel 8 a is not good. While looking through 30, the two-dimensional input can be performed by operating the operation unit 9 (dial, cross key, etc.).

The communication unit 12 performs data communication with the communication unit 32 of the EVF eyepiece unit 30.
As described above, the communication unit 14 performs data communication with the communication unit 28 of the interchangeable lens unit 20.
The signal processing / control unit 1 receives an image signal output from the image sensor 2 when capturing a still image or a moving image, performs image processing on the image signal, and acquires image data of the still image or the moving image. The signal processing / control unit 1 performs contrast AF processing and AE processing when capturing a still image or a moving image.
In contrast AF processing, high-frequency components of image data obtained by imaging of the image sensor 2 are extracted, and the extracted high-frequency components are integrated to obtain a focus evaluation value for AF. According to this focus evaluation value While evaluating the contrast of the image data, the focus adjustment lens of the lens system 26 of the interchangeable lens unit 20 is adjusted to a position where it is in focus.
In the AE process, the luminance of a subject is calculated using image data obtained by imaging of the image sensor 2, and the aperture amount (aperture value) of the aperture 26c during exposure and the exposure time (of the image sensor 2) according to the luminance of the subject. Electronic shutter speed) or mechanical shutter speed is calculated.

The signal processing / control unit 1 performs various types of image processing on image data obtained by imaging with the imaging device 2, such as color correction processing, gamma (γ) correction processing, compression processing, and decompression processing on the compressed image data. And so on.
The signal processing / control unit 1 can select a normal shooting mode, a playback mode, an image quality adjustment mode, and the like. When the image adjustment display control mode is selected, the image quality adjustment program stored in the Flash ROM of the recording unit 4 By performing the above, a live view display generated by imaging a subject with an imaging unit including the imaging device 2 and the lens system 26 and performing image processing on an image signal output from the imaging device 2 is used as an eyepiece for EVF. 30 and the rear LCD 8 with a touch panel, and the display mode for image quality adjustment can be adjusted for the eyepiece 30 for EVF and the rear LCD 8 respectively. The signal processing / control unit 1 includes an image quality adjustment unit 101, a touch detection unit 102, and a display control unit 103.

The image quality adjustment unit 101 displays information for image quality adjustment related to imaging on the EVF eyepiece unit 30 and the rear LCD 8 with a touch panel, which are displayed in live view, as shown in FIG. The tone curve adjustment data T, the adjustment data W for adjusting the white balance as shown in FIG. 6, the adjustment data E for adjusting the exposure as shown in FIG. In addition, the display mode for image quality adjustment, for example, the brightness of the image quality adjustment display can be adjusted for the EVF eyepiece 30 and the rear LCD 8 with a touch panel. The display mode is not limited to the brightness as described above, and may be, for example, the thickness, color, and transparency of the drawing line.
The image quality adjustment unit 101 sets the display mode when displaying the image quality adjustment display on the EVF eyepiece unit 30 inconspicuously compared with the live view display, and displays the image quality adjustment display on the rear LCD 8 with a touch panel. The display mode at the time is set to stand out compared to the live view display.
In other words, the image quality adjustment unit 101 sets the visibility when the image quality adjustment display is displayed on the EVF eyepiece unit 30 during imaging to be smaller than that of the live view display, and the image quality adjustment unit 101 displays the touch panel-attached rear LCD 8 during image quality adjustment. The visibility when displaying the image quality adjustment display is set larger than the live view display.

Here, the brightness setting will be described as an example of setting the visibility of the display form. As shown in FIG. 1B, the image quality adjustment unit 101 displays an image quality adjustment display on the eyepiece unit 30 for EVF during imaging. The brightness at the time of display is set to be smaller than that of the live view display, and the brightness at the time of displaying the image quality adjustment display on the rear LCD 8 with a touch panel is set to be higher than that of the live view display.
Specifically, when the image quality adjustment unit 101 detects that the user's eye is looking into the EVF eyepiece 30 by detection of the eyepiece sensor 3, the image quality adjustment unit 101 displays the image on the EVF eyepiece 30 during imaging. Decrease the brightness of the image quality adjustment display. For example, the brightness of the image quality adjustment display is set to be smaller than the brightness of the normal live view display by a preset value. The brightness of the image quality adjustment display may be set in advance by preparing a plurality of levels of brightness in which the brightness becomes dark at each different level, and the user selects and sets the brightness from these levels.

The image quality adjustment unit 101 increases the brightness of the image quality adjustment display displayed on the rear LCD 8 with a touch panel during image quality adjustment when the eye of the user does not look into the EVF eyepiece 30 by detection of the eye sensor 3. Set. The brightness of the image quality adjustment display is set larger by a preset value than the brightness of the normal live view display, for example. The brightness for the image quality adjustment display may be set in advance by preparing a plurality of levels of brightness in which brightness is increased for each different level, and the user selects and sets the brightness based on the brightness of each level.
The image quality adjustment unit 101 can display the image quality adjustment display more clearly than the live view display and with higher recognizability by making the image quality adjustment display brightness brighter than the live view display brightness during image quality adjustment. However, the brightness of the image quality adjustment display displayed on the rear LCD 8 with a touch panel may be set to be larger and the live view display may be turned off.
If the display mode is the thickness of the drawing line, the image quality adjustment unit 101 sets the thickness of the drawing line when displaying the image quality adjustment display on the EVF eyepiece unit 30 during imaging, At the time of image quality adjustment, the thickness of the drawing line when displaying the image quality adjustment display on the rear LCD 8 with a touch panel is set to be thick.
If the display mode is the color of the drawing line, the image quality adjustment unit 101 uses a low-saturation color (for example, gray) as the color of the drawing line when displaying the image quality adjustment display on the EVF eyepiece unit 30 during imaging. When the image quality adjustment is performed, the color of the drawing line when the image quality adjustment display is displayed on the rear LCD with touch panel 8 is set to a high saturation color.
When the display mode is the transparency of the drawing line, the image quality adjustment unit 101 sets a high transparency when displaying the image quality adjustment display on the EVF eyepiece unit 30 at the time of imaging. The transparency when the operation screen for image quality adjustment is displayed on the attached rear LCD 8 is set low.

The touch detection unit 102 detects a touch such as a user's finger on the touch panel 8a.
The image quality adjustment unit 101 receives the touch detection signal output from the touch detection unit 102 and performs image quality adjustment according to the operation for the image quality adjustment display. For example, when adjusting the tone curve, the image quality adjustment unit 101 detects the tone curve adjustment data T displayed on the EVF eyepiece unit 30 and the rear LCD 8 with the touch panel every time a touch on the touch panel 8a is detected. Switching to the order of adjustment data T1, T2,..., Tn. The image quality adjustment unit 101 adjusts the brightness of an image displayed in a live view according to the switched adjustment data T1, T2,.

  For example, in the normal shooting mode, the display control unit 106 reproduces image data that has been subjected to various types of image processing by the signal processing / control unit 1 and image data that has undergone image quality adjustment by the image quality adjustment unit 101 on the rear LCD 8 with a touch panel. . Further, the display control unit 106 reproduces image data whose image quality has been adjusted stored in the recording unit 4, for example, on the rear LCD 8 with a touch panel.

Next, the operation of the apparatus configured as described above will be described with reference to a display control flowchart shown in FIG.
In step S101, the signal processing / control unit 1 determines whether or not the power of the apparatus is turned on. If the power is not turned on as a result of this determination, the signal processing / control unit 1 enters a standby state.
When the power is turned on, the signal processing / control unit 1 determines whether or not the photographing mode is set in step S102. As a result of this determination, if the photographing mode is set, the signal processing / control unit 1 performs data communication with the lens control unit 21 of the interchangeable lens unit 20 via the communication units 14 and 28 in step S103. In step S104, contrast AF processing and AE processing are controlled. In the contrast AF process, high-frequency components of image data obtained by imaging with the image sensor 2 are extracted, and the extracted high-frequency components are integrated to obtain a focus evaluation value for AF, and an image is obtained according to the focus evaluation value. While evaluating the contrast of the data, the focus adjustment lens of the lens system 26 of the interchangeable lens unit 20 is adjusted to a position where it is in focus. In the AE process, the luminance of the subject is calculated using the image data obtained by the imaging of the imaging device 2, and the aperture amount (aperture value) of the diaphragm 26c at the time of exposure and the electronic shutter speed are calculated according to the luminance of the subject.

  In step S <b> 111, the signal processing / control unit 1 inputs a detection signal output from the eye sensor 3, and determines whether or not the user is looking into the eyepiece 30 for EVF by the eye sensor 3. Here, the user is looking into the EVF eyepiece 30 because the user changes the posture of the imaging apparatus main body so that the subject image in the EVF eyepiece 30 and the composition thereof are the best. This is when the consciousness is concentrated on the subject in the eyepiece 30 for EVF and the subject is imaged.

  As a result of this determination, if the user is looking into the EVF eyepiece 30, the signal processing / control unit 1 captures an image of the subject with the image sensor 2 through the lens system 26 in step S 112. The output image signal is subjected to image processing, and live view display is performed on the eyepiece 30 for EVF.

  In step S113, the signal processing / control unit 1 determines whether or not to perform image quality adjustment such as tone curve adjustment. The determination as to whether or not to perform the image quality adjustment is performed by, for example, selecting a button provided in the operation 9 by a user operation or a selection display for selecting whether or not to perform the image quality adjustment. It may be displayed on the attached rear LCD 8 and selected by touching the rear LCD 8 with a touch panel with a user's finger.

If the image quality adjustment is performed as a result of this determination, the image quality adjustment unit 101 displays an image quality adjustment display on the EVF eyepiece 30 in step S114, for example, tone curve adjustment data T as shown in FIG. 6, adjustment data W for adjusting white balance as shown in FIG. 6, adjustment data E for adjusting exposure as shown in FIG. 7, and the like are superimposed on the live view display.
FIG. 9 shows a live view subject image K displayed on the EVF eyepiece 30 and tone curve adjustment data T superimposed on the live view display. As shown in FIG. 2, the tone curve adjustment data T has a plurality of adjustment data T1, T2,..., Tn, so that any one of these adjustment data T1, T2,.

The selection of the adjustment data T1, T2,..., Tn is performed, for example, by the user operating a button provided on the operation unit 9.

In step S115, the image quality adjustment unit 101 determines whether or not the image quality adjustment of the tone curve or the like is to be ended. The end of the image quality adjustment is determined, for example, by detecting a user operation on an end button provided in the operation unit 9.
If the user does not operate the end button as a result of this determination, the image quality adjustment unit 101 returns to step S101 through step S131 and continues image quality adjustment. When the user operates the end button, in step S116, the signal processing / control unit 1 displays the image quality adjustment displayed on the EVF eyepiece 30, for example, the tone curve adjustment as shown in FIG. Display of the data T, the adjustment data W for adjusting the white balance as shown in FIG. 6, or the adjustment data E for adjusting the exposure as shown in FIG. 7 is ended.

In step S131, the signal processing / control unit 1 determines whether or not to perform a still image capturing operation. This still image is picked up by determining whether or not the first release switch of the release button in the operation unit 9 is half-pressed and then the 2nd release switch is fully pressed. If the first release switch is half-pressed as a result of this determination, the signal processing / control unit 1 performs shooting preparation operations such as AF processing, and then, when the 2nd release switch is fully pressed, AE operation for still image shooting. The image data of the still image obtained through the image sensor 2 is subjected to image processing.
In step S132, the signal processing / control unit 1 uses, for example, tone curve adjustment data T selected in the image quality adjustment display when image processing of still image data obtained via the image sensor 2 is performed. Based on this, the image quality of still image data is adjusted.
In step S133, the signal processing / control unit 1 adds a header to the image data of the still image whose image quality has been adjusted, generates a still image file, and stores the still image file in the recording unit 4.

On the other hand, as a result of the determination as to whether or not the user is looking into the EVF eyepiece 30 (step S111), if the user is not looking into the EVF eyepiece 30, the signal processing / control unit 1 In step S121, the subject is imaged by the imaging device 2 through the lens system 26, the image signal output from the imaging device 2 is subjected to image processing, and the live view display is performed on the rear LCD 8 with a touch panel.
Here, the reason why the user does not look into the EVF eyepiece unit 30 without approaching is that the user observes the live view display including the subject image displayed on the rear LCD 8 with the touch panel, and images the subject. It's time to go.

  In step S122, the signal processing / control unit 1 determines whether or not to perform image quality adjustment such as tone curve adjustment. The determination as to whether or not to perform the image quality adjustment is performed, for example, in order to select whether or not the user selects a button provided in the operation unit 9 by operating the button or whether or not to perform the image quality adjustment. May be displayed on the rear LCD 8 with a touch panel, and may be selected by touching the rear LCD 8 with a touch panel by a user's finger.

As a result of this determination, if image quality adjustment is to be performed, the signal processing / control section 1 displays an image quality adjustment display on the rear LCD 8 with a touch panel, for example, tone curve adjustment data T as shown in FIG. Adjustment data W for adjusting white balance as shown in FIG. 6 or adjustment data E for adjusting exposure as shown in FIG. 7 is superimposed on the live view display.
In this case, the image quality adjustment unit 101 sets, for example, the brightness of the image quality adjustment display displayed on the rear LCD 8 with a touch panel to a larger value by a preset value. The brightness of the operation screen for adjusting the image quality may be set in advance by selecting a plurality of levels of brightness in which the brightness is increased for each different level, and the user can select and set the brightness based on the brightness of each level. . By making the brightness of the image quality adjustment display larger than the brightness of the live view display, the image quality adjustment display is clearer than the live view display and can be displayed with higher recognizability. Furthermore, the live view display may be turned off.
FIG. 10 shows, for example, tone curve adjustment data T as an image quality adjustment display displayed on the rear LCD 8 with a touch panel. This image quality adjustment display shows a state in which the live view display of the subject image is turned off.

  In the selection of the tone curve adjustment data T, the image quality adjustment unit 101 detects the tone curve adjustment data T to be displayed on the rear LCD 8 with a touch panel each time a touch of the user's finger or the like on the touch panel 8a is detected, for example, as shown in FIG. As shown in Fig. 4, the order is changed to the order of adjustment data T1, T2, ..., Tn. The image quality adjustment unit 101 adjusts the brightness of the image displayed in the live view according to the switched adjustment data T1, T2,.

In step S124, the signal processing / control unit 1 determines whether or not the image quality adjustment such as the tone curve is to be ended. The end of the image quality adjustment is determined, for example, by detecting a user operation on an end button provided in the operation unit 9.
As a result of this determination, if the user does not operate the end button, the image quality adjustment unit 101 returns to step S101 through step S131 and continues image quality adjustment, as described above. When the user operates the end button, the signal processing / control section 1 displays the image quality adjustment display displayed on the rear LCD 8 with a touch panel, for example, tone curve adjustment data T as shown in FIG. The display of the adjustment data W for adjusting the white balance as shown in FIG. 6 or the adjustment data E for adjusting the exposure as shown in FIG. 7 is ended.
At the same time, the signal processing / control unit 1 images the subject with the imaging device 2 through the lens system 26, performs image processing on the image signal output from the imaging device 2, and performs live view display on the rear LCD 8 with a touch panel.

Thereafter, similarly to the above, in step S131, the signal processing / control unit 1 determines whether or not to perform the still image capturing operation. If the still image capturing operation is to be performed, the shooting preparation operation such as AF processing is performed. Subsequently, an AE operation is performed, and image data of a still image obtained via the image sensor 2 is subjected to image processing.
In step S132, the signal processing / control unit 1 performs, for example, the tone curve adjustment data T selected in the image quality adjustment display when the image data of the still image obtained through the image sensor 2 is processed. Based on this, the image quality of the still image data is adjusted. In step S133, the image data of the still image whose image quality has been adjusted is stored in the recording unit 4 as a still image file.

  On the other hand, if the imaging mode is not set, the signal processing / control unit 1 proceeds from step S102 to step S103, and determines whether or not the reproduction mode is set. As a result of this determination, if the playback mode is set, the signal processing / control section 1 executes the playback program stored in the ROM of the recording section 4 in step S142, and the stillness stored in the ROM. The image or moving image data is read out, and the still image or moving image data is displayed on the rear LCD 8 with a touch panel via the display control unit 103.

In step S143, the signal processing / control unit 1 determines whether to change the still image or moving image data to be displayed on the rear LCD 8 with the touch panel, and if it is changed to another still image or moving image data, In step S144, for example, the data of another still image or moving image stored in the Flash ROM is read, and the still image or moving image data is displayed on the rear LCD 8 with the touch panel via the display control unit 103.
If the playback mode is not set, the signal processing / control unit 1 moves from step S141 to step S145, performs data communication between the external devices, and, for example, stores still image data or moving image data stored in the Flash ROM. Send to equipment.

Next, the image quality adjustment operation (steps S114 and S123) will be described with reference to the image quality adjustment flowchart shown in FIG.
In step S201, the image quality adjustment unit 101 determines whether to perform tone curve adjustment. In this determination, the image quality adjustment unit 101 displays a screen for selecting an image quality adjustment item on the rear LCD 8 with a touch panel, and selects tone curve adjustment, white balance adjustment, or exposure adjustment from the screen. do it.
If the result of this determination is that the tone curve is adjusted, the image quality adjustment unit 101 reads out, for example, adjustment data T1 from the tone curve adjustment data T shown in FIG. The adjustment data T1 is superimposed on the live view display and displayed on the EVF eyepiece 30 and the rear LCD 8 with a touch panel.

The user touches the touch panel 8a of the rear LCD 8 with a touch panel in order to adjust the brightness when the subject is imaged, that is, to adjust the brightness of the live view display. Data T1, T2,..., Tn are switched.
In step S203, the image quality adjustment unit 101 determines whether or not the switched adjustment data T1, T2,..., Or Tn adjusts the dark part in the image data to dark, that is, whether the black part in the image data is emphasized. Determine whether or not.
As a result of this determination, if the adjustment data T1, T2,..., Or Tn is switched, the image quality adjustment unit 101, for example, in FIG. ) As shown in (b), the dark part of the image data is darkened by a predetermined brightness and is superimposed on the live view display and displayed on the EVF eyepiece 30 and the rear LCD 8 with a touch panel.

On the other hand, when the adjustment data Tn,..., T2, or T1 is switched, the image quality adjustment unit 101 moves from step S205 to step S206, for example, as shown in FIG. a) As shown in (b), the bright portion of the image data is brightened by a predetermined brightness and superimposed on the live view display and displayed on the EVF eyepiece 30 and the rear LCD 8 with a touch panel.
Note that changes in the luminance level of the image data when the tone curve is adjusted by selecting the tone curve adjustment data T (T1, T2,..., Or Tn) are shown in FIGS.

  When adjusting the tone curve, when the user's eye is approaching the EVF eyepiece 30 by detection of the eyepiece sensor 3, the image quality adjustment unit 101 moves to the EVF eyepiece 30 during imaging. The brightness of the image quality adjustment display to be displayed is set smaller by a preset value. Note that the brightness of the image quality adjustment display may be set by the user selecting from the brightness for each different stage.
