  Next, various operations of the digital single-lens reflex camera of the present embodiment having the above configuration will be described in detail.

  First, the operation of the liquid crystal monitor 28 display when the camera body 100 is turned on will be described with reference to the flowchart of FIG. In this embodiment, since the liquid crystal monitor 28 is a TFT liquid crystal type, the liquid crystal monitor 28 is illustrated as a TFT in the flowcharts of FIG.

  When the photographer turns on the main switch 61 of the camera to turn on the power, the system controller 50 starts the process from step S50. The system controller 50 confirms the display setting of the liquid crystal monitor 28 in step S51, and proceeds to step S52. The display setting of the liquid crystal monitor 28 can be performed based on a menu stored in advance in the camera.

  Here, FIG. 6 is a display setting screen of the liquid crystal monitor 28. This screen is a screen showing how the liquid crystal monitor 28 is set to always light when the power is turned on by the main switch 61 of the camera body 100. 7 is also a display setting screen of the liquid crystal monitor 28 as in FIG. In this screen, when the power is turned on by the main switch 61 of the camera body 100, whether or not the liquid crystal monitor 28 is turned on becomes the display setting of the liquid crystal monitor 28 when the camera body 100 was turned off last time. It is a screen which shows a mode that it sets.

  The system controller 50 proceeds to step S53 if the display setting of the liquid crystal monitor 28 is set to always display in step S52, and proceeds to step S54 otherwise. In step S53, the system controller 50 turns on the liquid crystal monitor 28 and displays photographing condition information.

  Specifically, as shown in FIG. 8, various information is displayed. Reference numeral 801 denotes a shutter speed, and reference numeral 802 denotes an aperture value. The shutter control unit 40 and the aperture control unit 305 perform control based on these set values. Reference numeral 803 denotes ISO sensitivity, which relates to the amplification factor of the signal output from the image sensor 14. Reference numeral 804 denotes a display indicating ON / OFF of the sounding body. When this display is made, for example, an electronic sound is emitted by operating the first shutter switch SW1. Reference numeral 805 denotes a red-eye reduction display. Regarding the light emission of the built-in strobe light 120, when this display is made, control for red-eye reduction is performed.

  Reference numeral 806 denotes a recordable number of sheets (shootable number of sheets) calculated from the remaining amount of the recording medium 200. This number varies according to the set image quality represented by 808. More specifically, 808 is represented by “RAW” indicating a lossless compression file format, or an irreversible compression file format, such as “L”, “M”, or “S” indicating image size. Reference numeral 807 denotes the state of charge of the power supply unit 86. Reference numeral 809 denotes a white balance setting, and reference numeral 810 denotes a selected photographing mode. By displaying such shooting condition information, the photographer can check the state and settings of the camera.

  Returning to FIG. 5, the system controller 50 confirms the previous power-off state in step S54, and proceeds to step S55. If it is determined in step S55 that the liquid crystal monitor 28 was previously turned on, the process proceeds to step S53, and the liquid crystal monitor 28 is turned on. On the other hand, if the previous power-off state in step S55 is the liquid crystal monitor 28 extinguished, the system controller 50 proceeds to step S56, and the liquid crystal monitor 28 remains off as shown in FIG.

  The system controller 50 proceeds to step S57 immediately after the process of step S53. In step S57, a foreign substance removal display operation process at the time of camera activation is performed. In this operation, foreign matter removal is displayed and foreign matter removal operation processing is executed. Specifically, this will be described later with reference to FIG. On the other hand, after the process of step S56, the system controller 50 performs a foreign substance removal operation process when the camera is activated (when the camera power is turned on) in step S58. The foreign substance removal operation process is a process in which the system controller 50 removes the foreign substance attached to the surface of the optical filter 44 by vibrating the piezoelectric element 43 by the piezoelectric element drive circuit 42. When step S57 or step S58 is completed, a series of this process at power-on is ended in step S59.

  According to this process, under the condition that the liquid crystal monitor 28 is displayed when the camera is activated, the photographing condition information display screen (FIG. 8) is displayed on the liquid crystal monitor 28 immediately after the camera is activated. Thereby, it is possible to promptly notify the photographer that the camera has been activated and the state and settings of the camera before photographing.

  Next, an operation for a change in the state of the DISP button 66 in the shooting preparation state of the camera body 100 will be described based on the flowchart of FIG.

  When the photographer presses the DISP button 66 in the shooting preparation state of the camera body 100, the system controller 50 calls a program for executing the flowchart of FIG. 9 from the second memory 52, and starts this processing from step S100. The system controller 50 confirms the state of the DISP button 66 in step S101. If the DISP button 66 is on, the system controller 50 proceeds to step S102 and confirms the lighting state of the liquid crystal monitor 28. On the other hand, if the DISP button 66 is off in step S101, the system controller 50 proceeds to step S105.

  If the liquid crystal monitor 28 is displaying the shooting condition information as shown in FIG. 8 in step S102, the system controller 50 proceeds to step S103 and turns off the liquid crystal monitor 28 as shown in FIG. On the other hand, if the liquid crystal monitor 28 is in the off state as shown in FIG. 10 in step S102, the system controller 50 proceeds to step S104, turns on the liquid crystal monitor 28, and displays the photographing condition information as shown in FIG. In step S105, the process ends.

  Next, an operation when the photographer presses the DISP button 66 while the image is reproduced and displayed on the liquid crystal monitor 28 in the camera body 100 (an operation in response to a change in the state of the DISP button 66) will be described with reference to the flowchart of FIG.

  The image recorded on the recording medium 200 connected to the camera body 100 can be displayed and confirmed on the liquid crystal monitor 28 when the photographer presses the playback button 69 of the camera body 100. When the photographer presses the playback button 69, the system controller 50 starts this processing from step S200. In step S201, the system controller 50 confirms the state of the DISP button 66. If the DISP button 66 is on, the system controller 50 proceeds to step S202. In step S202, the system controller 50 confirms playback display settings in the camera body 100, and proceeds to step S203.

  On the other hand, if the DISP button 66 is off in step S201, the system controller 50 proceeds to step S211. If the display setting for image reproduction is the display setting for simple shooting information display in step S203, the system controller 50 proceeds to step S204, and switches the display setting for image reproduction to the display setting for simple shooting information. Further, in step S205, the system controller 50 displays the simple photographing information at a predetermined position in the liquid crystal monitor 28 as shown in FIG. Otherwise, the process proceeds to step S206.

  If the display setting for image reproduction is the shooting information display setting in step S206, the system controller 50 proceeds to step S207, and switches the image reproduction display setting to the shooting information display setting. Further, in step S208, the system controller 50 displays detailed photographing information at a predetermined position in the liquid crystal monitor 28 as shown in FIG.

  If the display setting for image playback is a display setting other than the shooting information display setting in step S206, the system controller 50 proceeds to step S209 and switches the display setting for image playback to the display setting for only the image. Further, in step S210, the system controller 50 displays only an image that does not include shooting information as shown in FIG. A series of image display is performed, and the process ends in step S211.

  Next, an operation for a change in the state of the DISP button 66 in a state where menu display or INFO display is being performed on the liquid crystal monitor 28 of the camera body 100 will be described based on the flowchart of FIG.

  When the photographer presses the MENU button 67 in the shooting preparation state of the camera body 100, the system controller 50 switches the display content of the liquid crystal monitor 28 to the menu screen display shown in FIG. As a result, various settings such as settings relating to images, for example, settings relating to recording image quality and light adjustment correction, and settings for the presence or absence of electronic sound, can be made. When the photographer presses the DISP button 66 while the display content of the liquid crystal monitor 28 is menu screen display, the system controller 50 switches the display content of the liquid crystal monitor 28 to the screen display shown in FIG. Thereby, the setting state such as date, time, white balance (WB), etc. is displayed on the liquid crystal monitor 28 (INFO display).

  The system controller 50 starts this processing from step S300 in which the display content of the liquid crystal monitor 28 is in a menu display or INFO display. The system controller 50 checks the state of the DISP button 66 in step S301. If the DISP button 66 is on, the system controller 50 proceeds to step S302. If the DISP button 66 is off, the system controller 50 proceeds to step S306.

  The system controller 50 confirms the display content of the liquid crystal monitor 28 in step S302, and proceeds to step S303. If the display content of the liquid crystal monitor 28 is menu display in step S303, the system controller 50 proceeds to step S304 and sets the display content of the liquid crystal monitor 28 to INFO display (FIG. 17). On the other hand, if the display content of the liquid crystal monitor 28 is other than menu display (INFO display) in step S303, the system controller 50 proceeds to step S305, and changes the display content of the liquid crystal monitor 28 to menu display (FIG. 16). In step S306, the process is terminated.

  Next, an operation for a change in the state of the DISP button 66 during BULB shooting in the camera body 100 will be described based on the flowchart of FIG.

  When the photographer operates the mode dial 60 and the main electronic dial 65 to a predetermined state, the shutter speed is changed to a BULB (bulb) state, long exposure is possible, and the shutter 9 is moved while the shutter button 62 is pressed. Shooting in the open state is possible. The system controller 50 sets the shutter speed to the BULB state, and starts this processing from step S400 when the photographer presses the shutter button 62 and the second shutter switch SW2, 64 is turned on.

  In step S401, the system controller 50 starts BULB shooting exposure and proceeds to step S402. The system controller 50 proceeds to step S403 if the liquid crystal monitor 28 is turned on in step S402, and proceeds to step S406 if the liquid crystal monitor 28 is turned off. In step S403, the system controller 50 displays the elapsed exposure time on the liquid crystal monitor 28 as shown in FIG. At this time, the exposure elapsed time is displayed in white characters on the black background in the liquid crystal monitor 28.

  Next, the system controller 50 confirms the state of the DISP button 66 in step S404. If the DISP button 66 is on, the system controller 50 proceeds to step S405 and turns off the liquid crystal monitor 28 as shown in FIG. On the other hand, if the DISP button 66 is off in step S404, the system controller 50 proceeds to step S408.

  If the DISP button 66 is on in step S406, the system controller 50 proceeds to step S407 and displays the elapsed exposure time in the liquid crystal monitor 28 as shown in FIG. At this time, similarly to step S404, the elapsed exposure time is displayed in white characters on the black background in the liquid crystal monitor 28. On the other hand, if the DISP button 66 is off in step S406, the system controller 50 proceeds to step S408.

  If the first shutter switch SW1, 63 is in the OFF state in step S408, the system controller 50 proceeds to step S409 and ends the exposure. On the other hand, the system controller 50 returns to step S402 if the first shutter switch SW1, 63 remains on in step S408. In step S410, the process ends.

  In the present embodiment, when the shooting condition information display screen is displayed on the liquid crystal monitor 28, black characters are displayed against a white background so that the characters can be easily seen even when the surroundings are bright, such as outdoors in the daytime. . On the other hand, when the exposure elapsed time is displayed on the liquid crystal monitor 28 during bulb photography, which is generally used in a dark environment, white characters are displayed against a black background. Thereby, for example, even in a dark environment where astronomical photography is performed, glare caused by the display on the liquid crystal monitor 28 is suppressed, and the photographer has good visibility and is easy to use.

  In this embodiment, black characters are displayed on a white background when the photographing condition information display screen is displayed on the liquid crystal monitor 28, and black is displayed when the exposure elapsed time is displayed on the liquid crystal monitor 28 during bulb photographing. However, the display is not limited to a specific display color. When the photographing condition information display screen is displayed on the liquid crystal monitor 28, dark characters are displayed on a light background, and when the exposure elapsed time is displayed on the liquid crystal monitor 28 during bulb photographing, the light background is light. It is good also as a setting which displays with a character.

  Next, the distance measurement mode selection sequence of the camera body 100 will be described with reference to the flowchart of FIG.

  When the photographer operates the distance measurement mode selection button 79 that also serves as the right direction selection button in the shooting preparation state of the camera body 100, the distance measurement mode selection state is entered. At this time, the system controller 50 starts the distance measurement mode selection sequence from step S700 at a predetermined timing. In the shooting preparation state, the distance measurement mode information 601 is displayed in the shooting condition display area on the shooting condition information display screen shown in FIG. 21 displayed on the liquid crystal monitor 28.

  On the other hand, when the distance measurement mode is selected, the screen of the liquid crystal monitor 28 shifts to a distance measurement mode selection screen (imaging condition selection screen) shown in FIG. In the distance measurement mode selection screen, a series of selectable distance measurement modes are displayed in the distance measurement mode selection area (imaging condition selection area) 605 in the shooting condition selection area. Here, the ranging mode selection area (imaging condition selection area) 605 on the ranging mode selection screen and the imaging condition display area on the imaging condition information display screen have a band-like area having substantially the same width in the height direction of the screen. It is set to become. Therefore, the photographer can easily recognize the position where the distance measurement mode is displayed even if the photographer changes from the photographing condition information display screen to the distance measurement mode selection screen.

  In addition, the currently selected ranging mode is highlighted. Further, a guidance 606 indicating that the ranging mode is being selected is displayed at the top of the ranging mode selection screen, and the name of the currently selected ranging mode is displayed immediately above the ranging mode selection area 605. A guidance 607 is displayed. By displaying the guidances 606 and 607, the photographer can clearly understand the currently selected item.

  In step S701, the system controller 50 checks the state of the left direction selection button 78. If the left direction selection button 78 is on, the system controller 50 proceeds to step S702, and if the left direction selection button 78 is off, the system controller 50 proceeds to step S706. In step S702, the system controller 50 performs state transition (transition) in the ranging mode. At this time, the display of the ranging mode selection area 605 on the ranging mode selection screen (shooting condition selection screen) on the liquid crystal monitor 28 is “ONE SHOT” (FIG. 22) → “AI SERVO” (FIG. 24) → “AI FOCUS”. "" (FIG. 23) in the order of state transition.

  Next, the system controller 50 proceeds to step S703, updates the display on the liquid crystal monitor 28 to display the selected distance measuring mode, and proceeds to step S704. In step S704, the system controller 50 confirms whether the end of the distance measurement mode selection state is selected. If the end of the distance measurement mode selection state is selected, the system controller 50 proceeds to step S705, and the display on the liquid crystal monitor 28 is changed to the shooting condition. Update to the information display screen. Then, in step S709, this process ends.

  If the end of the distance measurement mode selection state is not selected in step S704, the system controller 50 returns to step S701. Here, “selecting the end of the distance measurement mode selection state” means that the end is selected by operating the shutter button 62 (the first shutter switches SW 1 and 63 are turned on) or the SET button 80.

  The system controller 50 confirms the state of the right direction selection button 79 in step S706. If the right direction selection button 79 is on, the system controller 50 proceeds to step S707, and if the right direction selection button 79 is off, the system controller 50 proceeds to step S704. In step S707, the system controller 50 performs state transition (transition) in the ranging mode. At this time, the display of the distance measurement mode selection area 605 on the distance measurement mode selection screen (shooting condition selection screen) on the liquid crystal monitor 28 is “ONE SHOT” (FIG. 22) → “AI FOCUS” (FIG. 23) → “AI SERVO”. The state transitions in the order of FIG.

  Next, the system controller 50 proceeds to step S708 and updates the display of the distance measurement mode selection area 605 on the distance measurement mode selection screen (imaging condition selection screen) on the liquid crystal monitor 28 so as to display the selected distance measurement mode. The process proceeds to step S704.

  Similarly, the white balance setting state is entered by operating the white balance selection button 77. When the white balance setting state is entered, a white balance setting screen (shooting condition selection screen) shown in FIG. 25 is displayed. In FIG. 25, in the white balance selection area (imaging condition selection area) 608 of the white balance setting screen, white balance icons that can be set are displayed in a line, and the currently set white balance icon is highlighted. The Guidance 609 explaining the icon displayed in reverse is displayed in an area above the white balance selection area 608. The white balance selection area (imaging condition selection area) 608 is set to be a band-like area having substantially the same width in the height direction of the screen as the imaging condition display area on the imaging condition information display screen.

  By operating the photometry mode selection button 78, the photometry mode setting state is entered. When the photometric mode setting state is entered, a photometric mode setting screen (imaging condition selection screen) shown in FIG. 26 is displayed. In FIG. 26, in the photometry mode setting selection area (imaging condition selection area) 610, settable photometry mode icons are displayed in a line, and the currently set photometry mode icon is highlighted. Guidance 611 for explaining the icon displayed in reverse is displayed in an area above the photometry mode selection area 610. The metering mode setting selection area (imaging condition selection area) 610 is set to be a band-like area having substantially the same width in the height direction of the screen as the imaging condition display area on the imaging condition information display screen.

  The drive mode setting state is entered by operating the drive mode setting button 75. When the drive mode setting state is entered, a drive mode setting screen (imaging condition selection screen) shown in FIG. 27 is displayed. In FIG. 27, in the drive mode setting selection area (imaging condition selection area) 612, settable drive mode icons are displayed in a line, and the currently set drive mode icon is highlighted. Guidance 613 for explaining the icon displayed in reverse is displayed in an area above the drive mode selection area 612. The drive mode setting selection area (imaging condition selection area) 612 is set to be a belt-like area having substantially the same width in the height direction of the screen as the imaging condition display area on the imaging condition information display screen.

  Each mode selection operation and process is the same as the distance measurement mode selection method.

  Next, an AF ranging point selection operation sequence in the camera body 100 will be described based on the flowchart of FIG.

  When the photographer operates the distance measuring point selection button 72 in the shooting preparation state of the camera body 100, the distance measuring point selection state is entered. At this time, the system controller 50 starts the distance measuring point selection sequence from step S600 at a predetermined timing. In the shooting preparation state, the distance measuring point information 602 is displayed in the lower area of the central band-like portion on the shooting condition information display screen shown in FIG. 29 displayed on the liquid crystal monitor 28.

  On the other hand, when the focus detection point is selected, the display on the liquid crystal monitor 28 is a screen display shown in FIG. 30 in which the focus detection point information 602 is extracted and enlarged. Furthermore, at the top of the screen, information indicating that a distance measuring point is being selected is displayed, and immediately above the distance measuring point information display, information indicating whether it is currently automatically selected or arbitrarily selected. Is displayed. As a result, it becomes clear that the focus detection point is selected, and the selected focus detection point is easy to understand.

  The system controller 50 confirms whether or not the SET button 80 has been pressed in step S601. If the SET button 80 is pressed, the system controller 50 proceeds to step S602. If the SET button 80 has not been pressed, the system controller 50 proceeds to step S607. In step S602, the system controller 50 confirms the distance measuring point selection state before the SET button 80 is pressed. If the distance measuring point selection state is automatic selection, the system controller 50 proceeds to step S603, and the distance measuring point selection state is arbitrarily selected. If so, the process proceeds to step S606.

  In step S603, the system controller 50 moves the distance measurement point to the center and updates the distance measurement point on the distance measurement point selection screen to the central distance measurement point selection screen shown in FIG. 31, and proceeds to step S604 as an optional selection state. . In step S606, the system controller 50 automatically selects a distance measuring point and updates the distance measuring point on the distance measuring point selection screen to the distance measuring point automatic selection screen shown in FIG. 30, and proceeds to step S604 as an automatic selection state. . That is, when the SET button 80 is pressed, automatic selection is switched to arbitrary selection, and arbitrary selection is switched to automatic selection.

  In step S604, the system controller 50 confirms whether or not the end of the distance measuring point selection state is selected. If the end of the distance measuring point selection state is selected, the system controller 50 proceeds to step S605 and displays the display on the liquid crystal monitor 28 as the imaging condition. Update to the information display screen. In step S619, the process ends.

  If the end of the distance measuring point selection state is not selected in step S604, the system controller 50 returns to step S601. Here, “the end of the distance measuring point selection state is selected” means that the shutter button 62 is operated (the first shutter switch SW1, 63 is turned on), the distance measuring point selection button 72 is depressed, or a predetermined distance measurement is performed. The end is selected as the point selection state timer elapses.

  In step S607, the system controller 50 confirms whether or not the upward selection button 76 has been pressed. If the upward selection button 76 has been pressed, the system controller 50 proceeds to step S608, and if the upward selection button 76 has not been pressed. Proceed to step S610. The system controller 50 confirms the distance measuring point selection state before the up direction selection button 76 is pressed in step S608. If the distance measuring point selection state is automatic selection, the system controller 50 proceeds to step S603, and the upward direction selection button. If the distance measuring point selection state before pressing 76 is an arbitrary selection, the process proceeds to step S609. In step S609, the system controller 50 moves the distance measuring point upward, updates the distance measuring point on the distance measuring point selection screen to the upper distance measuring point selection screen shown in FIG. 32, and proceeds to step S604.

  In step S610, the system controller 50 checks whether or not the downward selection button 77 has been pressed. If the downward selection button 77 has been pressed, the system controller 50 proceeds to step S611, and if the downward selection button 77 has not been pressed. The process proceeds to step S613. The system controller 50 confirms the distance measuring point selection state before the down direction selection button 77 is pressed in step S611. If the distance measuring point selection state is automatic selection, the system controller 50 proceeds to step S603, and the down direction selection button. If the distance measuring point selection state before 77 is pressed is an arbitrary selection, the process proceeds to step S612. In step S612, the system controller 50 moves the distance measuring point downward, updates the distance measuring point on the distance measuring point selection screen to the lower distance measuring point selection screen shown in FIG. 33, and proceeds to step S604.

  The system controller 50 confirms whether or not the left direction selection button 78 has been pressed in step S613. If the left direction selection button 78 has been pressed, the system controller 50 proceeds to step S614, and if the left direction selection button 78 has not been pressed. The process proceeds to step S616. The system controller 50 confirms the distance measuring point selection state before the left direction selection button 78 is pressed in step S614. If the distance measuring point selection state is automatic selection, the system controller 50 proceeds to step S603, and the left direction selection button. If the distance measuring point selection state before pressing 78 is an arbitrary selection, the process proceeds to step S615. In step S615, the system controller 50 moves the distance measuring point to the left and updates the distance measuring point on the distance measuring point selection screen to the left distance measuring point selection screen shown in FIG. 35, and proceeds to step S604.

  In step S616, the system controller 50 checks whether or not the right direction selection button 79 has been pressed. If the right direction selection button 79 has been pressed, the system controller 50 proceeds to step S617, and if the right direction selection button 79 has not been pressed. The process proceeds to step S604. In step S617, the system controller 50 confirms the distance measuring point selection state before the right direction selection button 79 is pressed. If the distance measuring point selection state is automatic selection, the system controller 50 proceeds to step S603, and the right direction selection button. If the distance measuring point selection state before 79 is pressed is an arbitrary selection, the process proceeds to step S618. In step S618, the system controller 50 moves the distance measuring point to the right and updates the distance measuring point on the distance measuring point selection screen to the right distance measuring point selection screen shown in FIG. 34, and proceeds to step S604.

  Next, the foreign substance removal operation and display processing when the liquid crystal monitor 28 in the camera main body 100 is activated in the display-on state (when the power is turned on) will be described based on the flowchart of FIG.

  The system controller 50 calls the foreign substance removal operation and display process of FIG. 36 in step S57 of FIG. 5, and starts this process from step S800. In step S802, the system controller 50 first checks whether the first shutter switch SW1, 63 is turned on. If the first shutter switch SW1, 63 is not turned on, the process proceeds to step S803, and if the first shutter switch SW1, 63 is turned on, the process proceeds to step S810.

  In step S803, the system controller 50 determines whether or not automatic foreign substance removal execution (described later) is set. If foreign matter removal automatic execution is set, the process advances to step S804. If the automatic foreign substance removal execution is not set, the process proceeds to step S816, and the process is terminated.

  In step S804, the system controller 50 starts a foreign substance removing operation for removing the foreign substance on the surface of the optical filter 44 by vibrating the piezoelectric element 43 by the piezoelectric element driving circuit 42, and proceeds to step S805. In step S805, the system controller 50 displays on the partial area of the photographing condition information display screen of the liquid crystal monitor 28 that the foreign matter removing operation is being performed, and proceeds to step S806. Details of the display in step S805 will be described later. Note that a partial area of the shooting condition information display screen is an area unrelated to the area for displaying the exposure information included in the pre-shooting information.

  In step S806, the system controller 50 determines whether or not a predetermined foreign matter removal drive time has elapsed since the start of the foreign matter removal operation. If the predetermined foreign matter removal drive time has elapsed, the process proceeds to step S812, and if the predetermined foreign matter removal drive time has not elapsed, the process proceeds to step S807. In step S812, the system controller 50 ends the foreign matter removal operation, and proceeds to step S813.

  In step S813, the system controller 50 checks whether or not the first shutter switch SW1 · 63 is turned on. If the first shutter switch SW1, 63 is not turned on, the process proceeds to step S814, and if the first shutter switch SW1, 63 is turned on, the process proceeds to step S810.

  In step S814, the system controller 50 determines whether or not a predetermined display time set in advance has elapsed since the start of the foreign substance removal operation display. If the predetermined display time has elapsed, the process proceeds to step S815. If the predetermined foreign matter removal drive time has not elapsed, the process returns to step S813. Here, the predetermined display time is longer than the predetermined foreign matter removal driving time (the driving time of the piezoelectric element 43 by the piezoelectric element driving circuit 42), and the photographer visually recognizes the display on the liquid crystal monitor 28. Sufficient time is set.

  In step S815, the system controller 50 ends the foreign matter removal operation display, and ends the present process in step S816. The display on the liquid crystal monitor 28 in the state where the foreign matter removal operation display is ended in step S815 is the same as the display (FIG. 8) in the state where the present process is started.

  In step S807, the system controller 50 confirms whether or not the first shutter switches SW1 and 63 are turned on. If the first shutter switch SW1, 63 is not turned on, the process returns to step S805. If the first shutter switch SW1, 63 is turned on, the process advances to step S808 to end the foreign matter removal operation, and the foreign matter removal operation display on the liquid crystal monitor 28 is finished in step S809.

  In step S810, the system controller 50 performs photometry / distance measurement processing, and in step S811, displays shooting information (aperture value calculated from the photometric value, shutter speed, exposure level, etc.) as shown in FIG. In the example of FIG. 38, since the manual mode is selected as the shooting mode and the exposure is set manually, the exposure level 604 is set to the display (FIG. 8) in the state where the present process is started. It is displayed. After completing the process in step S811, the system controller 50 proceeds to step S814 and ends the series of processes.

  FIG. 37 is an example of the shooting condition information display screen of the liquid crystal monitor 28 in step S805. An icon indicating that the foreign matter removing operation is being performed is displayed in an area 603 for displaying the number of shootable images and the like in the lower right part of the shooting condition information display screen of FIG. Main shooting information such as shutter speed 801, aperture value 802, ISO sensitivity 803, etc. is displayed in the same manner as normal pre-shooting information (FIG. 8). Thereby, the photographer can simultaneously confirm the information necessary for photographing and the foreign matter removing operation.

  Further, according to this process, as described above, it is possible to start shooting immediately by turning on the first shutter switch SW1, 63 from the state of step S805. Since the display form in FIG. 37 (FIG. 37) is similar to the normal pre-shooting information display (FIG. 8), it is easy to understand that the photographer can intuitively take a picture. It has become. Further, the display of the icon indicating that the foreign object removal operation is being performed is set to be displayed for a longer time than the actual foreign object removal operation time so that the photographer can easily recognize even a small icon.

  Next, the foreign substance removal operation and display processing when the liquid crystal monitor 28 of the camera body 100 is activated in the display-off state (when the power is turned on) will be described with reference to the flowchart of FIG.

  The system controller 50 calls the foreign substance removal operation process of FIG. 39 in step S58 of FIG. 5, and starts this process from step S900. In step S902, the system controller 50 checks whether or not the first shutter switches SW1 and 63 are turned on. In step S803, the system controller 50 determines whether or not automatic foreign substance removal is set, and distributes the processes. The sequence in FIG. 39 is the same as the sequence in FIG. 36 except that there is no processing related to display, and thus detailed description thereof is omitted.

  Next, the foreign substance removal operation process when the camera body 100 is turned off will be described based on the flowchart of FIG.

  When the photographer turns off the main switch 61 of the camera body 100, the system controller 50 starts this processing from step S1000. The system controller 50 first determines in step S1001 whether or not foreign matter removal automatic execution is set. If foreign matter removal automatic execution is set, the system controller 50 proceeds to step S1002, and if foreign matter removal automatic execution is not set. The process proceeds to step S1007.

  In step S1002, the system controller 50 starts a foreign matter removing operation for removing the foreign matter on the surface of the optical filter 44 by vibrating the piezoelectric element 43 by the piezoelectric element driving circuit 42, and proceeds to step S1003. In step S1003, the system controller 50 checks whether or not the display on the liquid crystal monitor 28 is on. If the display on the liquid crystal monitor 28 is on, the system controller 50 proceeds to step S1004. If the display on the liquid crystal monitor 28 is off, step S1005 is performed. Proceed to

  In step S1004, the system controller 50 displays a screen indicating that the foreign substance removing operation is being performed on the liquid crystal monitor 28, and proceeds to step S1005. FIG. 41 shows a screen displayed on the liquid crystal monitor 28, and only an icon indicating that the foreign matter removing operation is being performed is displayed on the black background screen. In other words, the foreign matter removing operation is displayed using the entire screen of the liquid crystal monitor 28. Since this icon is displayed largely at the center of the screen, the photographer can easily recognize that the foreign object removing operation is in progress. Further, since the display during the foreign substance removal operation is a display of a form completely different from the display form of the pre-photographing information as shown in FIG. 8, for example, the photographer can easily recognize that the photographing operation cannot be performed. it can.

  The system controller 50 continues the foreign matter removal operation until a predetermined time has elapsed from the start of the foreign matter removal operation in step S1005, and proceeds to step S1006 when the predetermined time has passed. In step S1006, the system controller 50 ends the foreign matter removal operation display, and proceeds to step S1007. In step S1007, the system controller 50 turns off the display on the liquid crystal monitor 28. Subsequently, in step S1008, the system controller 50 performs a shutdown process of the camera body 100, and the process ends in step S1009. That is, the camera is automatically turned off after the foreign substance removing operation is completed.

  In the present embodiment, the camera body 100 is configured such that the photographer can arbitrarily execute the foreign substance removal operation by a menu operation.

  Next, processing for executing the foreign substance removal operation by the photographer's menu operation in the camera body 100 will be described based on the flowchart of FIG.

  When the photographer selects the item “sensor cleaning: automatic” from the menu screen shown in FIG. 43 displayed on the liquid crystal monitor 28, the system controller 50 starts this processing from step S1100. In step S1101, the system controller 50 displays the setting menu screen for the foreign substance removal operation shown in FIG. 44 as a submenu on the liquid crystal monitor 28, and proceeds to step S1102.

  In step S1102, the system controller 50 confirms whether or not the first shutter switches SW1 and 63 are turned on. If the first shutter switch SW1 · 63 is not turned on, the process proceeds to step S1103. If the first shutter switch SW1 · 63 is turned on, the process proceeds to step S1112.

  In step S1103, the system controller 50 determines whether “Execute Now” has been selected on the setting menu screen of FIG. If “execute now” is selected, the process proceeds to step S1104. If “execute now” is not selected, the process proceeds to step S1114. In step S1104, the system controller 50 starts a foreign substance removing operation for removing the foreign substance on the surface of the optical filter 44 by vibrating the piezoelectric element 43 by the piezoelectric element driving circuit 42, and proceeds to step S1105.

  In step S1105, the system controller 50 displays on the liquid crystal monitor 28 that the foreign matter removing operation is being performed, and then proceeds to step S1106. The display screen of the liquid crystal monitor 28 in step S1105 is the same as the display screen (FIG. 41) of the liquid crystal monitor 28 in step S1004 of FIG.

  In step S1106, the system controller 50 determines whether a predetermined time has elapsed since the start of the foreign substance removal operation. If the predetermined time has elapsed, the process proceeds to step S1107. If the predetermined time has not elapsed, the process proceeds to step S1108. In step S1107, the system controller 50 displays a foreign matter removing operation setting menu screen (FIG. 44) on the liquid crystal monitor 28, and the process ends in step S1117.

  In step S1108, the system controller 50 checks whether or not the first shutter switch SW1 · 63 is turned on. When the first shutter switch SW1 · 63 is not turned on, the process returns to step S1105, and when the first shutter switch SW1 · 63 is turned on, the process proceeds to step S1110.

  The system controller 50 continues the foreign matter removal operation until a predetermined time has elapsed from the start of the foreign matter removal operation in step S1110. When the predetermined time has passed, the system controller 50 proceeds to step S1111. In step S <b> 1111, the system controller 50 ends the foreign matter removal operation display, and proceeds to step S <b> 1112. In step S1112, the system controller 50 performs photometry / ranging processing, and proceeds to step S1113. In step S1113, shooting information (aperture value calculated from the photometric result, shutter speed, exposure level, etc.) is displayed on the liquid crystal monitor 28, for example, as shown in FIG.

  In step S1114, the system controller 50 confirms whether or not “setting” is selected on the setting menu screen of FIG. If “SETTING” is selected, the process proceeds to step S1117. If “SETTING” is not selected, the process proceeds to step S1115. In step S1117, the system controller 50 accepts the setting for turning on / off automatic execution of foreign matter removal, and returns to step S1101.

  45 and 46 are screens displayed on the liquid crystal monitor 28 in step S1117. The character icon at the bottom of the screen is highlighted, and the icon can be toggled from “Yes” → “No” → “Yes” with the left direction selection button 78 and the right direction selection button 79. The change is accepted and confirmed by the SET button 80. When “Yes” is selected, automatic execution of foreign matter removal is set to on, and when “No” is selected, automatic execution of foreign matter removal is set to off.

  In step S1115, the system controller 50 confirms whether the MENU button 67 has been pressed. If the MENU button 67 has been pressed, the process proceeds to step S1116, and if the MENU button 67 has not been pressed, the process returns to step S1101. In step S1116, the system controller 50 exits the foreign matter removal operation setting menu screen, displays the menu screen one level higher (FIG. 43) on the liquid crystal monitor 28, and ends this processing.

  As described above, according to the present embodiment, the setting display area related to shooting on the shooting condition information display screen and the setting selection area related to shooting on the shooting condition selection screen are substantially the same. Therefore, even if the shooting condition information display screen and the shooting condition selection screen are switched, the relationship between the current setting value and the option can be easily understood.
