  Hereinafter, the present invention will be described through embodiments of the invention, but the following embodiments do not limit the invention according to the claims. In addition, not all the combinations of features described in the embodiments are essential for the solving means of the invention.

  FIG. 1 is a cross-sectional view of a main part of a camera system 1 according to the present embodiment. In the present embodiment, a camera system 1 will be described as an example of an electronic device. The camera system 1 is a lens-interchangeable single-lens reflex camera that functions as an imaging device by combining a camera body 2 and a replaceable photographing lens 3.

  The photographic lens 3 includes a lens group 4 including a focus lens, a zoom lens, and an anti-vibration lens, an aperture 5, an angular velocity sensor 6 that detects shake of the camera system 1, a driving device (not shown) that drives the lens group 4, and the like. . The angular velocity sensor 6 detects an angular velocity around at least two axes orthogonal to the optical axis. The drive device has a plurality of motors composed of, for example, a vibration wave motor and a VCM, drives the focus lens in the optical axis direction, and drives the anti-vibration lens in a direction different from the optical axis direction.

  The photographing lens 3 has a lens CPU 7 that controls the entire photographing lens 3 and cooperates with the camera body 2.

  The camera body 2 retracts so that the light beam from the photographic lens 3 is reflected and guided to the finder optical system 8 and the light beam from the photographic lens 3 is incident on the image sensor 9 composed of a CCD or a CMOS. A main mirror 10 that swings with respect to the retracted position is provided.

  A part of the main mirror 10 is a semi-transmissive area, and the camera body 2 includes a sub-mirror 12 that reflects the light beam transmitted through the semi-transmissive area to the focus detection sensor 11. The sub mirror 12 swings in conjunction with the main mirror 10, and when the main mirror 10 takes the retracted position, the sub mirror 12 also retracts from the light flux. The focus detection sensor 11 detects the focus state of the incident light beam by the phase difference method.

  The light beam reflected by the main mirror 10 at the reflection position is guided to the finder optical system 8 through the focusing screen 13 and the pentaprism 14. The finder optical system 8 includes a plurality of lenses, and the user can confirm the object field by the finder optical system 8.

  A part of the light beam passing through the pentaprism 14 is guided to the photometric sensor 15. The photometric sensor 15 measures the luminance distribution of the object scene by measuring the light beam incident on the photographing lens 3 for each of a plurality of regions. A GPS (Global Positioning System) module 16 is provided above the pentaprism 14.

  Furthermore, the camera body 2 includes a microphone 17 that captures the sound of the object scene at a position that does not interfere with the photographing lens 3 in the vicinity of the mount portion of the photographing lens 3. The camera body 2 includes a speaker 18 that emits a beep sound in the vicinity of the finder optical system 8.

  When the main mirror 10 is in the retracted position, the light flux from the photographing lens 3 enters the image sensor 9 through the low-pass filter 19. An imaging board 20 is provided in the vicinity of the imaging device 9, and a rear monitor 21 is provided behind the imaging board 20 so as to face the outside.

  The camera body 2 includes an attitude sensor 22. The attitude sensor 22 detects the attitude of the camera system 1. Specifically, whether the camera system 1 is held horizontally or vertically, or whether the camera system 1 is in a forward tilted posture that allows the user to easily view the rear monitor 21 or the like. Is detected.

  FIG. 2 is a block diagram of the camera system 1 according to the present embodiment. Elements that are the same as those in FIG. 1 are given the same reference numerals, and redundant descriptions are omitted.

  The imaging substrate 20 includes a drive circuit 23 that drives the imaging device 9, an A / D conversion circuit 24 that converts the output of the imaging device 9 into a digital signal, an image processing control circuit 25 configured by an ASIC, and signals from the imaging device 9. A contrast AF circuit 26 for extracting the high-frequency component of the.

  The image processing control circuit 25 performs image processing such as white balance adjustment, sharpness adjustment, gamma correction, and gradation adjustment on the image signal converted into the digital signal, and also performs image compression such as JPEG to generate an image file. Generate. The generated image file is stored in the secondary recording medium 34. The secondary recording medium 34 may be a recording medium such as a flash memory that can be attached to and detached from the camera body 2, or may be a recording medium such as an SSD (Solid State Drive) built in the camera body 2. good.

  The image signal subjected to the image processing is displayed on the rear monitor 21 under the control of the rear monitor control circuit 28. If the image signal taken immediately after shooting is displayed for a predetermined time, the image corresponding to the image file recorded on the secondary recording medium 34 can be viewed by the user.

  Further, a live view display can be realized by sequentially displaying an object scene image that is continuously photoelectrically converted by the image sensor 9 on the rear monitor 21 without being recorded on the secondary recording medium 34. When the live view display is being executed, the camera system 1 continues to recognize the image of the object scene as a through image. As a result, a shooting operation involving image processing such as face recognition and smile detection can be executed.

  Further, an object scene image that is continuously photoelectrically converted by the image sensor 9 is recorded in, for example, MPEG, H.264, or the like. If moving image compression processing such as H.264 is performed by the image processing control circuit 25 and recorded in the secondary recording medium 34, moving image shooting can be realized. At this time, the sound of the object scene collected by the microphone 17 is also compressed and recorded in synchronization with the moving image data. The frame rate of the generated moving image is selected and set from a plurality of frame rates such as 30 fps, for example.

  The contrast AF circuit 26 extracts a high-frequency component of the imaging signal from the imaging device 9 to generate an AF evaluation value signal, and detects a focus lens position where the AF evaluation value signal becomes maximum. Specifically, a predetermined high-frequency component is extracted from the image signal input from the image processing control circuit 25 using a bandpass filter, and detection processing such as peak hold and integration is performed to generate an AF evaluation value signal. . The generated AF evaluation value signal is output to the camera body CPU 27.

  The lens CPU 7 drives the anti-vibration lens in the photographing lens 3 in a direction different from the optical axis direction so as to cancel the camera shake detected by the angular velocity sensor 6 to realize optical camera shake correction. The camera shake correction is not limited to such optical camera shake correction, but adopts an image sensor drive type camera shake correction in which a drive mechanism is added to the image sensor 9 to drive in a direction different from the optical axis direction and cancel the camera shake. You can also.

  Furthermore, an electronic camera shake that calculates a motion vector between a plurality of images output from the image processing control circuit 25 and controls image readout position so as to cancel the calculated motion vector between images and cancels camera shake. Corrections can also be employed. Optical camera shake correction and image sensor-driven camera shake correction are particularly suitable for still image shooting and are also applied to moving image shooting. Electronic camera shake correction is suitable for moving image shooting. These methods can be selectively and additionally employed.

  As described above, the photometric sensor 15 measures the luminance distribution of the object scene by measuring the luminous flux incident on the photographing lens 3 for each of a plurality of areas, and outputs the measurement result to the camera body CPU 27. The camera body CPU 27 calculates an exposure value according to the selected photometry mode. As a metering mode, a split metering mode that balances bright and dark parts, a center-weighted metering mode that properly exposes the center of the screen, a spot metering mode that properly exposes a narrow area of the selected focus point, and the like can be selected. .

  The calendar unit 54 includes a crystal oscillator, a timekeeping integrated circuit, and the like, and holds calendar information such as year / month / day / hour / minute / second. The camera body CPU 27 can appropriately detect information related to time from the calendar unit 54. The GPS module 16 receives a GPS signal from a GPS satellite and calculates latitude, longitude, and altitude information where the camera body 2 exists. The camera body CPU 27 can appropriately detect information regarding the position where the camera body 2 is present from the GPS module 16.

  The flash ROM 29 is an EEPROM (registered trademark) and is a storage device that stores various adjustment values and setting values in addition to a program for operating the camera system 1. Specifically, it stores setting values such as AF adjustment data, AE adjustment data, manufacturing date / time data, and setting switch setting history. Further, the flash ROM 29 stores a usage history for a predetermined number of times of the menu setting screen and the user guide screen.

  Among the setting values stored in the flash ROM, setting values that are set or changed by the user are prepared as menu items on a setting screen displayed on the rear monitor 21. On the setting screen, the menu items are classified into a plurality of types according to the type, and are further hierarchized into a tree structure based on their dependency in each classification and managed by the camera body CPU 27.

  The camera system 1 has a guide function for explaining to the user the influence of the type of the set value and the change of the set value. The guide function holds contents to be explained to the user as a guide screen. Like the menu items, the guide screens are classified into a plurality of types according to the type, and are further hierarchized into a tree structure within each category and managed by the camera body CPU 27. From the guide screen, it is also possible to set setting values related to the shooting conditions after the setting screen. However, the guide screen guides the user and does not necessarily set the shooting conditions of the camera system 1.

  The RAM 30 is a high-speed RAM such as a DRAM in which a program stored in the flash ROM 29 is expanded and the camera body CPU 27 can access at high speed. In particular, various adjustment values and setting values that are frequently referred to are also copied from the flash ROM 29 to facilitate access from the camera body CPU 27.

  The rear monitor control circuit 28 performs display control for displaying the menu setting screen and the user guide screen read from the flash ROM 29 on the rear monitor 21 in addition to the image processed as described above. Further, a touch panel sensor is stacked on the surface of the rear monitor 21, and when the user operates the touch panel sensor while visually recognizing the menu items of the rear monitor 21, the coordinates and the coordinates are displayed. The menu item is output to the camera body CPU 27.

  The attitude sensor 22 detects the attitude of the camera system 1 as described above. The posture sensor 22 is configured by combining a sensor that detects the posture in a uniaxial direction depending on whether a small sphere moving by gravity blocks the infrared light of the photo interrupter. When it is desired to detect an accurate angle as the posture of the camera system 1, a triaxial acceleration sensor or the like is used. In particular, in the present embodiment, it is only necessary to detect whether or not the user is in the forward tilt posture in which the user can easily view the rear monitor 21. The direction sensor 33 is formed by combining two or three-axis magnetic sensors, and detects which direction the camera system 1 is facing.

  The event information acquisition unit 31 acquires event information held at a specific facility via a network. The event information acquisition unit 31 may include a network connection unit such as a wireless LAN and a program that acquires event information in a specific facility from the network. In addition, the event information acquisition unit 31 is not limited to accessing information published on the network, but may access a database related to event information that the photographer has built in advance. In addition, the event information acquisition unit 31 can be formed so that the photographer accesses a database stored in the flash ROM 29 as schedule information, for example, instead of connecting to a network.

  The release switch 32 is a two-stage switch. When the user presses the release switch 32 halfway, the camera body CPU 27 performs shooting preparation operations such as autofocus and photometry. When the user further depresses the release switch 32, the camera body CPU 27 starts a still image / moving image shooting operation.

  The camera body CPU 27 controls the entire camera system 1 in cooperation with the lens CPU 7. In the present embodiment, the camera body CPU 27 performs control to display at least one of the setting screen and the user guide screen on the rear monitor 21.

  FIG. 3 is a rear external view of the camera body 2. Elements that are the same as those in the other drawings are given the same reference numerals, and redundant descriptions are omitted.

  On the rear surface of the camera body 2, the rear end of the finder optical system 8 and the rear monitor 21 are sandwiched, and the rear dial 35, the cross button 36, the enter button 37, the playback mode button 38, the delete button 39, and the confirmation button 40 are interposed. Etc. are arranged.

  The camera body 2 operates in the playback mode when the playback mode button 38 is pressed. In the reproduction mode, the captured image data stored in the secondary recording medium 34 is displayed on the rear monitor 21. By rotating the rear dial 35 in this state, the captured images displayed on the rear monitor 21 are sequentially switched. Thus, the back dial 35 forms a selection unit for selecting an image.

  When an image on the rear monitor 21 is displayed in the reproduction mode, when the delete button 39 is pressed, the image can be deleted from the secondary recording medium 34 loaded in the camera body 2. However, when the image deletion is completed in one operation, the photographed image data may be deleted due to an erroneous operation. Therefore, when the confirmation button 40 is pressed after the delete button 39, the deletion is executed.

  The cross button 36 has switches that are individually turned on / off at four locations, top, bottom, left, and right. Thereby, for example, the cross button 36 can be used when selecting an image or option two-dimensionally arranged on the rear monitor 21. In addition, individual functions may be temporarily assigned to the four switches included in the cross button 36.

  The decision button 37 is pressed when inputting an instruction to decide an option selected by the cross button 36. As a result, as in the case of the confirmation button 40, it is possible to prevent any operation from being confirmed by one operation.

  FIG. 4 is a diagram illustrating one display image displayed on the rear monitor 21 when the camera body 2 is in the playback mode. In the illustrated example, a plurality of reduced images 49 corresponding to a plurality of photographed image data are displayed on the rear monitor 21. The plurality of reduced images 49 are arranged in the order of imaging as indicated by, for example, a one-dot chain line in the figure.

  The user operates the rear dial 35 with respect to the plurality of reduced images 49 displayed on the rear monitor 21 to move the selection frame 43 indicated by a dotted line in the drawing in the order of shooting indicated by a one-dot chain line in the drawing. Thereby, photographed image data corresponding to one reduced image 49 is specified. By pressing the delete button 39 in this state, deletion of the captured image data corresponding to the reduced image 49 is instructed.

  In the rear monitor 21, a selection frame 43 whose display form has changed as shown by a solid line in the drawing is added to each of the reduced images 49 of the image data A to E instructed to be deleted by the user as described above. The Furthermore, when the user presses the confirmation button 40 after specifying all the captured image data A to F to be deleted, the captured image data is deleted. As described above, the user can collectively delete the captured image data A to F corresponding to the selected reduced image 49.

  In the above example, a plurality of reduced images 49 are displayed on the rear monitor 21 and an image to be deleted is indicated. However, one image may be displayed on the entire rear monitor 21 so that an image to be deleted can be identified while checking details. In this case, for example, the delete button 39 and the confirmation button 40 are pressed for each image to delete the photographed image data one by one.

  FIG. 5 is a diagram showing the structure of the image file 50 generated by the camera system 1. The image file 50 stores tag data 51, thumbnail image data 52, and main image data 53.

  The main image data 53 corresponds to captured image data captured by the camera system 1. On the other hand, the thumbnail image data 52 has a lower resolution, color depth, and the like than the main image data 53. This facilitates handling when displaying a list of a plurality of main image data 53 stored by the camera system 1.

  The tag data 51 stores specifications of the camera system 1 that captured the main image data 53, imaging conditions, and the like. When the JPEG (Joint Photographic Experts Group) format is adopted as the file format of the main image data 53, the image file with tag data includes information defined as an EXIF file.

  More specifically, in addition to basic information such as the manufacturer, specifications, firmware version number, and open F value of the camera system 1 that captured the image data 53, the exposure time, F value, ISO value, and focus during shooting Shooting condition information such as distance and shooting date / time is recorded. Furthermore, tag data 51 includes shooting environment information related to the date / time, orientation, orientation, position, event, and the like detected by the calendar unit 54, orientation sensor 22, orientation sensor 33, GPS module 16, event information acquisition unit 31 and the like of the camera system 1. Can be added to and recorded.

  In the camera system 1, the tag data 51 is generated when the release button is pressed halfway and the shooting condition is fixed. In the camera system 1, when the release button is pressed halfway down to full press, the generated tag data 51 is stored in the image file 50 together with the main image data 53. Therefore, the above-described shooting environment information and shooting condition information are also included in the image file including the shot image data.

  FIG. 6 is a flowchart showing a control procedure executed by the camera body CPU 27 in the camera system 1. While the camera system 1 is powered on, the camera main body CPU 27 determines whether or not designation has been made to delete a captured image that has already been captured and stored (step S101).

  Note that the camera body CPU 27 may determine “YES” in step S101 when a plurality of images are deleted. Here, as an example of “a plurality of photographed image data has been deleted”, there is a case where a predetermined number of images have been deleted after entering a single reproduction mode and exiting. Further, when deletion of a plurality of photographed images is designated within a predetermined threshold time, for example, 5 minutes, that is, when the deletion operation is repeatedly performed, it is determined that a plurality of photographed image data has been deleted. May be.

  Here, the predetermined time may be selected by the user using a selection unit including the cross button 36 and the determination button 37 from the options displayed on the rear display unit on the setting screen. Also, a predetermined number may be selected by the user using a selection unit including the cross button 36 and the determination button 37 from the options displayed on the rear display unit on the setting screen.

  When it is detected that the captured image data has been deleted (step S101: YES), the camera body CPU 27 temporarily stores the captured image data instructed to be deleted for redisplay (step S102). If the secondary recording medium 34 has a sufficient capacity, the camera body CPU 27 may leave the deleted captured image data as it is and set a flag indicating that deletion is instructed to each of the captured image data. .

  If the secondary recording medium 34 has no capacity, the camera body CPU 27 may delete the main image data 53 from the image file 50 and temporarily store the thumbnail image data 52 and the tag data 51. Thereby, when making an inquiry to be described later, an image to be inquired can be displayed to the user.

  Thereafter, the camera body CPU 27 predicts whether or not the camera body 2 is in a shooting posture (step S103). That is, for example, when the release switch 32 is half-pressed by the user, the camera body CPU 27 predicts that the camera system 1 is in a shooting posture (step S103: YES).

  When the camera body CPU 27 determines that the camera system 1 is in a shooting state (step S103: YES), the position and direction where the image deleted from the output of the GPS module 16 and the direction sensor 33 is taken are almost the same. If it is, the automatic reflection mode (step S104) is activated. The contents of the automatic reflection mode will be described later with reference to other drawings. In the automatic reflection mode, the camera body CPU 27 performs shooting at the time of shooting in which data of the shot image is generated for the shot image designated to be deleted. The reason for deletion is inferred from the conditions, and the photographing condition corresponding to the estimated reason for deletion is calculated.

  The camera body CPU 27 sets the calculated shooting condition (step S105), and causes the camera system 1 to perform shooting (step S106). As described above, when the camera system 1 is in the shooting posture after the shot image is deleted, the camera body CPU 27 completes shooting using the automatic reflection mode. In step S106, when the remaining capacity of the secondary recording medium 34 is tight, the camera body CPU 27 executes shooting after deleting or compressing the captured image data temporarily stored in step S102. Also good.

  As described above, when the camera body CPU 27 determines that the camera system 1 is in a shooting posture, the camera body CPU 27 executes shooting without hindering the user's operation. However, this is not the case when the user intentionally sets the camera body 2 not to give priority to shooting.

  Further, for example, when the camera body CPU 27 detects that the user repeats a reproduction operation for reproducing and displaying the photographed image on the rear monitor 21, the camera body CPU 27 determines that the camera system 1 is not in a photographing posture (step S103: NO). Alternatively, the camera body CPU 27 determines that the posture sensor 22 determines the tilt of the camera system 1 and that the camera system 1 is not in a shooting posture (step S103: NO). Furthermore, the camera main body CPU 27 operates when the user operates the cross button 36, operates the touch panel sensor of the rear monitor 21, that is, when a different one from the release switch 32 is operated. The system 1 determines that it is not in a shooting posture.

  If the camera body CPU 27 determines that the camera system 1 is not in a shooting posture after deletion of a captured image (step S103: NO), then it determines whether re-shooting of the deleted captured image is permitted. (Step S108).

  For example, the camera body CPU 27 refers to the shooting date and time of the image from the tag data 51 of the image file 50 of the deleted captured image. Then, when the current date and time of the deleted captured image are close, for example, within 1 hour, the camera system CPU 27 is in a state close to the deleted image shooting environment, It is determined that photographing is permitted (step S108: YES). On the other hand, if the shooting date / time of the deleted image and the current date / time are largely separated, the camera body CPU 27 determines that it is no longer allowed to re-shoot the shooting target of the deleted image (step S108: NO).

  Note that the camera body CPU 27 also determines whether or not re-photographing is permitted by comparing the shooting position information referenced from the tag data 51 of the deleted image with the current position information referenced from the GPS module 16. I can judge. The camera body CPU 27 also compares the event information referenced from the tag data 51 of the deleted image with information such as the event content, event start time, and event end time referenced from the event information acquisition unit 31. It can be determined whether or not re-photographing is allowed.

  Still further, the camera body CPU 27 may refer to other information such as azimuth information, weather, season, and the like by the azimuth sensor 33, and determines whether re-photographing is permitted together with these information. May be. Furthermore, you may provide the reception part which receives the instruction | indication of the re-photographing from a user.

  When the camera body CPU 27 determines that re-photographing is allowed as described above (step S108: YES), the camera body CPU 27 activates the guide mode (step S109). In the guide mode, the camera body CPU 27 estimates the reason for deletion of the captured image designated to be deleted from the shooting conditions at the time of shooting when the data of the captured image is generated, and displays a display screen reflecting the estimated reason for deletion. Prepare and display on the rear monitor 21. Here, when there are a plurality of deletion reasons that can be estimated, a plurality of guides may be sequentially activated.

  As a result, the camera body CPU 27 encourages the user to re-shoot, and displays a guide screen or setting screen corresponding to the detected environment information and the estimated reason for deletion on the rear monitor 21. As a result, the camera body CPU 27 guides the user to change the shooting condition so as to eliminate or suppress the estimated reason for deletion.

  Shooting conditions are set as a result of guiding in the guide mode (step S105). The photographing target of the deleted image is re-photographed under the photographing conditions that reflect both the reason for deletion and the user's intention (step S106). Further, when the camera body CPU 27 determines that re-photographing is not permitted as described above (step S108: NO), the camera body CPU 27 activates the confirmation mode (step S110). In the confirmation mode, the camera body CPU 27 inquires the user about the reason for deleting the deleted captured image, and collects the reason for deletion with higher accuracy. Thereby, the camera body CPU 27 can reflect the reason for deletion with higher accuracy in the initial value of the shooting condition set in the camera system 1. The captured image whose deletion reason has been confirmed in the confirmation mode is completely erased from the secondary recording medium 34 (step S406).

  Note that, when the photographing in step S106 is completed, the camera body CPU 27 checks whether or not there remains a photographed image that is temporarily saved after being deleted in step S102 (step S107). When the temporarily stored photographed image remains (step S107: NO), the camera body CPU 27 checks again whether the camera system 1 is in a photographing posture (step S103). If there is no remaining captured image (step S107: NO), the camera body CPU 27 ends the series of controls.

  FIG. 7 is a flowchart showing the control procedure of the camera body CPU 27 in the automatic reflection mode. When the automatic reflection mode is started (FIG. 6, step S104), the camera body CPU 27 first acquires peripheral environment information related to the surrounding environment in which the camera system 1 captures an image (step S201). The surrounding environment information includes, for example, date / time information acquired from the calendar unit 54, orientation of the camera system 1 acquired from the direction sensor 33, latitude, longitude and altitude acquired from the GPS module 16, map information acquired from a flash ROM, etc. The event information acquired from the information acquisition unit 31 is included.

  Next, the camera body CPU 27 retrieves the peripheral environment information of the image designated to be deleted from the tag data 51 of the deleted image temporarily stored in step S102, and the peripheral environment similar to the peripheral environment information acquired in step S201. A deleted image including information is extracted (step S202). Furthermore, the camera body CPU 27 estimates the reason for deleting the image with reference to the shooting condition information of the deleted image extracted in step S202 (step S203).

  Further, the camera body CPU 27 calculates shooting conditions that do not cause the deletion reason from the estimated deletion reason (step S204), and ends the automatic reflection mode. As a result, the camera body CPU 27 can set the shooting condition in which the reason for deletion hardly occurs in the camera system 1 (FIG. 6, step S105) and execute shooting. Therefore, the shooting performed in step S106 better reflects the user's shooting intention.

  In this case, the camera body CPU 27 sets the shooting conditions currently set in the camera system 1 and the shooting conditions of the deleted image shot in the environment closest to the current surrounding environment from the images instructed to be deleted. Compare. Then, when the current shooting conditions and the conditions of the image instructed to be deleted are the same, the camera body CPU 27 later deletes the image shot under the current shooting conditions for the same deletion reason as the image already specified for deletion. It is determined that there is a high possibility of being designated for deletion, and different shooting conditions are calculated.

  For example, if the current time acquired from the calendar unit 54 is evening or night, the camera body CPU 27 estimates that the captured image was dark because of the deletion reason (step S203). Therefore, the camera body CPU 27 calculates a shutter speed at a lower speed than the current setting and an aperture amount at the lower speed of the shutter (CPU 204). Further, the camera body CPU 27 may determine that camera shake is likely to occur due to setting the shutter speed to the low speed time, and may enable the camera shake correction function in the camera system 1. Thereby, it is possible to suppress the occurrence of underexposure that tends to occur during evening or night shooting.

  The camera body CPU 27 is deleted based on the surrounding environment of the camera system 1 acquired based on the position information acquired from the GPS module 16, the direction information acquired from the direction sensor 33, the map information acquired from the flash ROM 29, etc. The reason for deleting the designated image is estimated (step S203). The camera main body CPU 27, for example, is likely to cause overexposure in the photographed image when it can be inferred from the map information that the object to be photographed is a landscape such as a coast, a mountainous area, and the like. An imaging condition that is several steps lower than the exposure value calculated from the photometric result is calculated (step S204). Thereby, occurrence of overexposure due to overexposure can be suppressed.

  Furthermore, when the user is in the spring mountain, the camera body CPU 27 may calculate and set the setting value in the image processing control circuit 25 that is changed so that the colors of the fresh green trees and leaves are bright. If it is determined that the user is in the mountains in autumn, the setting value in the image processing control circuit 25 may be calculated and set so that the color of the autumnal leaves changes to be bright.

  Still further, when the user is in the aquarium, the camera main body CPU 27 operates in the image processing control circuit 25 so that the sensitivity, white balance, and color are suitable for photographing fish in an indoor aquarium. The set value may be calculated and set. If the camera body CPU 27 determines that the user is shooting fireworks based on the information acquired from the event information acquisition unit 31, image processing is performed so that the optimal exposure and fireworks can be captured vividly. The set value in the control circuit 25 may be calculated and set.

  Note that when the release switch 32 is fully pressed, the camera body CPU 27 shoots images with the setting value of the shooting condition that was initially set and the setting value of the shooting condition calculated in the automatic reflection mode. May be. The camera body CPU 27 determines that the user wants to leave the image to be captured when the user re-photographs the same image in a short time after instructing to delete a plurality of images. The camera body CPU 27 records the shooting target as a moving image on the secondary recording medium 34 for a few seconds (3 to 5 seconds) after the release switch 32 is half-pressed to prepare for shooting such as AE and AF. Also good. Thereby, the image to be photographed can be reliably left.

  FIG. 8 is a flowchart showing a control procedure executed by the camera body CPU 27 in the guide mode. As already described, the guide mode is activated when the camera system 1 is not in a shooting state even though the camera system 1 is in a surrounding environment where a shot image designated for deletion can be retaken. In the guide mode, it is intended to guide the user to obtain a photographed image more in line with the user's intention by photographing the photographing target in the deleted image under appropriate photographing conditions.

  As described above, when the guide mode is activated (FIG. 7, step S109), the camera body CPU 27 re-shoots the shooting target of the shot image designated to be deleted, although the camera system 1 is not in a shooting posture. It is confirmed that the situation is acceptable. Therefore, the camera body CPU 27 alerts the user, for example, by emitting a beep from the speaker 18 and checks whether or not the user intends to re-shoot (step S301).

  When the camera main body CPU 27 refers to the output of the attitude sensor 22 or the like and responds to the beep sound, such as when the user lifts the camera system 1 and observes the rear monitor, there is a possibility of re-shooting. (Step S301: YES). However, when there is no response from the user, for example, the camera body CPU 27 determines that the user does not intend to perform re-shooting when a predetermined threshold time has elapsed since entering step S301. The guide mode may be terminated (step S301: NO).

  Next, the camera body CPU 27 checks whether or not the bracket mode is set in the camera system 1 (step S302). When the bracket mode is set in the camera system 1, the camera system 1 performs shooting a plurality of times while changing the shooting conditions. Therefore, the camera body CPU 27 determines that the guide for narrowing down the shooting conditions is unnecessary, and ends the guide mode (step S302: NO).

  When the bracket mode is not set in the camera system 1 (step S302: NO), the camera body CPU 27 estimates the deletion reason caused by the shooting condition at the time of shooting for the deleted shot image data. (Step S303). Next, the camera body CPU 27 prepares a display screen to be displayed on the rear monitor 21 based on the estimated reason for deletion (step S304). The display screen prepared by the camera body CPU 27 includes a guide screen and a setting screen. The relationship between the deletion reason and the display screen will be described later with an example.

  FIG. 9 is a diagram showing an example of a guide screen which is one of the display screens. A guide message 41 for guiding re-shooting to the rear monitor 21 and time, place, and event can be selected at that time. A guide item 42 is displayed as an option. The user instructs one of the guide items 42 to the camera body CPU 27 using the cross button 36 and the determination button 37.

  Referring to FIG. 8 again, the camera body CPU 27 displays the prepared display screen on the rear monitor 21 (step S305), and waits to accept a user instruction (step S306). If the instruction from the user is not input even after the preset threshold time has elapsed, the camera body CPU 27 determines that the guide mode has been interrupted and ends the guide mode (step S306: NO). On the other hand, when an instruction from the user such as selecting the guide item 42 is input (step S306: YES), the camera body CPU 27 checks whether there is a display screen to be displayed next (step S307).

  If there is a display screen to be displayed next (step S307: YES), the camera body CPU 27 prepares the display screen again (step S304) and displays it on the rear monitor 21 (step S305). If there is no longer any display screen (step S307: NO), the camera body CPU 27 calculates the changed shooting condition based on the user's instruction to the guide (step S308).

  In the guide mode, the display screen displayed on the rear monitor 21 by the camera body CPU 27 may include a setting screen instead of the guide screen. FIG. 10 is a diagram illustrating one such setting screen. As illustrated, setting items 44 and setting value selection candidates 45 are displayed on the setting screen. In addition, the set value includes a mark that can be distinguished from other selection candidates that are currently set. In the illustrated example, the current set value is surrounded by a rectangular frame.

  In the example shown in FIG. 9, the guide screen displays options using characters. However, the camera body CPU 27 may generate a result of applying the guide item to the captured image designated to be deleted by image processing and display the entire rear monitor 21. In this case, the guide item is displayed superimposed on the image. Thereby, the user can grasp | ascertain the content of a guide screen concretely and intuitively.

  In this way, the setting screen has the same contents as the setting menu screen displayed on the rear monitor 21 in the setting mode of the camera system 1, and the setting value candidates to be selected are directly displayed. Next, the determination of the camera body CPU 27 in the guide mode will be specifically described.

  When the shooting time is selected on the guide screen shown in FIG. 9, the camera body CPU 27 confirms the current time from the calendar unit 54 when “shooting time” is selected. Then, it is determined whether shooting is performed under dark conditions from dusk to night or under other bright conditions.

  Note that the camera body CPU 27 may obtain the position information from the GPS module 16 and the event information from the event information acquisition unit 31 and take those information into account. Moreover, when it has the function to acquire information from the outside, you may consider information, such as a weather.

  Next, the camera body CPU 27 displays another guide screen as the next display screen. That is, the camera body CPU 27 determines that the camera system 1 is shooting in the evening, evening, or night from the information on the time. In such a case, a guide screen to be displayed next is prepared (step S304) and displayed on the rear monitor 21 (step S305).

On the guide screen displayed in step S305, for example, the following guide item 42 that is effective when the subject to be photographed is dark is displayed.
1. Sunset / Sunset 2. Night view / night view portrait ISO sensitivity / noise 4. Image stabilization / Redness reduction / Flash off 5. Shooting technique

  For example, when sunset / sunset is selected by the user's operation of the cross button 36, the camera body CPU 27 further displays a guide screen for selecting either sunset or sunset on the rear monitor 21. When either one is selected, the white balance and exposure are corrected for sunset or sunset according to the user's selection. The camera body CPU 27 may display a setting screen that allows the user to make fine settings.

  When the night view / night view portrait is selected by the user's operation of the cross button 36, the camera body CPU 27 displays a guide screen recommending either the night view mode or the night view portrait on the rear monitor 21. When the night scene is selected, the camera body CPU 27 displays a setting screen for setting the shutter speed to the low speed side and prohibiting the flash from being emitted, and allows the user to set it.

  On the other hand, when the night view portrait is selected on the guide screen, the camera body CPU 27 sets the strobe to forced light emission, sets the shutter speed to the low speed side, and turns on the face detection function. Further, since camera shake is likely to occur during night view boat rate shooting, the camera body CPU 27 may execute camera shake correction control using a plurality of the above-described camera shake correction methods, such as turning on the camera shake correction function. .

  Further, the camera main body CPU 27 executes face recognition when the night view / night view portrait is selected, determines the night view portrait if the face can be recognized, and determines the night view shooting if the face cannot be recognized. May be omitted.

  The camera body CPU 27 displays a guide screen for selecting ISO sensitivity or noise on the rear monitor 21 when ISO sensitivity / noise is selected by the user's operation of the cross button 36. When the ISO sensitivity is selected, the camera body CPU 27 displays a setting screen for setting the ISO sensitivity on the rear monitor.

  On the other hand, when the noise is selected, the camera body CPU 27 displays the currently selected ISO sensitivity, and the ISO sensitivity setting screen so that an ISO sensitivity lower than the currently set ISO sensitivity can be set. Is displayed. In such a case, the setting screen is displayed instead of the guide screen as shown in FIG.

  The camera body CPU 27 selects “hand shake”, “red-eye reduction”, or “strobe emission prohibition” on the rear monitor 21 when hand shake / red-eye reduction / strobe emission prohibition is selected by the user's operation of the cross button 36. A guide screen is displayed and set according to the item selected by the user.

  This setting may be changed according to the user operation history. Specifically, the camera body CPU 27 selects an item from the settings executed by the user in the past shooting in a dark situation, or items that have not been operated so much, that is, items that are not familiar with the settings. Or just select it.

  When the shooting technique is selected by the user's operation of the cross button 36, the camera body CPU 27 displays a guide screen for selecting “Blur background / stop subject” on the rear monitor 21. Then, when “blur background” is selected, the camera body CPU 27 decreases the aperture value of the aperture 5 and sets it so that the background is blurred. The camera body CPU 27 sets the shutter speed to the high speed side when “shoot with the subject stopped” is selected.

Next, an example of guide contents effective when the subject to be photographed is bright will be described. In such a case, the camera body CPU 27 displays the following guide items on the rear monitor 21.
1. Active D-writing 2. Backlight Flash off,
4). 4. ISO sensitivity / continuous shooting / self-timer Shooting technique

  When the active D-lighting is selected by the user's operation of the cross button 36, the camera body CPU 27 displays a setting screen for selecting the effect of the active D-lighting on the rear monitor 21. Thereby, the user can make active D-lighting effective and enjoy the effect.

  Note that active D-lighting is a method of shooting and image processing that maintains the gradation of a shot image while preventing the occurrence of overexposure and underexposure. That is, when shooting, after shooting with a low exposure value that does not cause overexposure, gradation correction processing is performed to raise the luminance of the pixel region from low luminance to intermediate luminance to generate an image file. As a result, an image close to proper exposure can be generated as a whole while maintaining the gradation of the bright portion.

  Similarly, in the case of shooting, after shooting with a higher exposure value at which blackout does not occur, gradation correction processing is performed to depress the luminance of the pixel area from low luminance to intermediate luminance to generate an image file. As a result, it is possible to generate an image close to proper exposure as a whole while maintaining the gradation of the dark part.

  In this way, the exposure value calculated from the output of the photometric sensor 15 is changed to an under value or an over value by a predetermined number of steps, and gradation correction processing is performed on the obtained image, whereby A shooting mode that achieves tonality maintenance and overall proper exposure is called active D-lighting.

  The guide items will be described again. The camera body CPU 27 performs control so that the forced flash mode is set to the flash when “backlight” is selected by the user's operation of the cross button 36, and prohibits the flash from being emitted when the flash emission prohibition is selected. To control.

  The camera body CPU 27 controls the rear monitor 21 to set the forced flash mode to the strobe when “ISO sensitivity / continuous shooting / self-timer” is selected by the user's operation of the cross button 36. When strobe light emission prohibition is selected, a guide screen for selecting “ISO sensitivity”, “continuous shooting”, and “self-timer” is displayed, and the selected item is set.

  In the guide item “ISO sensitivity / continuous shooting / self-timer”, the display content may be changed according to the operation history of the user. Specifically, the camera body CPU 27 selects an item from the settings performed by the user in shooting in a bright situation such as the past morning or daytime, or an item that has not been operated so much, that is, a setting. You can select items that you are not familiar with. Since the shooting technique is the same as the guide item when the shooting target is dark, a duplicate description is omitted.

  Next, a description will be given of a guide screen displayed in the next stage when a shooting location is selected on the guide screen shown in FIG. The camera body CPU 27 acquires the current location from the GPS module 16 when “shooting location” is selected. In addition, referring to the map information or the like, it is determined whether the image is taken at the sea, at the mountain, indoors or outdoors. The camera body CPU 27 may acquire and add time information from the calendar unit 54, event information from the event information acquisition unit 31, and weather information acquired from the outside.

  Even if the location and facilities are known, it may be unclear whether it is indoor or outdoor. For example, even if it is a school, there is a case where it cannot be distinguished whether it is in a school building or a schoolyard. Also, since an aquarium or the like may include outdoor facilities, for indoor / outdoor, a guide screen may be displayed to allow the user to select a guide screen.

  Further, when the indoor is selected, the camera body CPU 27 may display a setting screen or a guide screen according to the use of the facility such as a school, an aquarium, a wedding hall, or the like, from the facility information of the acquired position. The map information or the like may be stored in the flash ROM 29, or may be acquired from the outside through an internet line or the like.

  When the camera body CPU 27 acquires the information regarding the shooting location as described above, the camera body CPU 27 displays a guide screen or a setting screen corresponding to the specified shooting location on the rear monitor 21. Note that the camera body CPU 27 may change the shooting condition with reference to the date / time information acquired from the calendar unit 54 in addition to the information regarding the shooting location. For example, if the facility is a school and it is a graduation season, the image processing control circuit 25 may suppress the color tone and make it seem like it is.

  Similarly, when the outdoor is selected, the camera body CPU 27 may guide shooting settings according to the acquired position information (mountain, sea, school, railway, etc.). Also in this case, the camera body CPU 27 may acquire the date / time information from the calendar unit 54 and set according to the season and time zone.

  Furthermore, when the “event” guide item is selected on the guide screen shown in FIG. 9, the camera body CPU 27 determines that the event is based on the position information acquired from the GPS 16 and the date / time information acquired from the calendar unit 54. Event information of a place where the user is present is acquired from the information acquisition unit 31. Here, when a plurality of event candidates are detected, the camera body CPU 27 may display a plurality of event information on the rear monitor 21 to allow the user to select the corresponding event.

  As described above, in the present embodiment, after the user instructs deletion of a plurality of images, a shooting guide corresponding to the reason for deletion and the shooting situation is executed in the guide mode. This makes it easy to capture an image with an image quality according to the user's intention.

  FIG. 11 is a flowchart showing a control procedure executed by the camera body CPU 27 in the confirmation mode. In the confirmation mode (FIG. 6, step S110), the camera body CPU 27 determines that the user has time because the camera system 1 is not in a shooting posture.

  Therefore, in the confirmation mode, the camera body CPU 27 inquires the user about the reason for the deletion of the photographic image data designated to be deleted (step S401). When the confirmation mode is activated, the camera body CPU 27 may emit a beep from the speaker 18 to alert the user that the camera system 1 is requesting confirmation.

  FIG. 12 is a diagram illustrating contents displayed on the rear monitor 21 when step S401 of the above procedure is executed. On the rear monitor 21, a reduced image 49 of a plurality of images instructed to be deleted, an inquiry item 46 for the reduced image 49, and an option 47 as a response to the inquiry item 46 are displayed together.

  The user moves the selection frame 48 to any one of the options 47 with the cross button 36 and presses the enter button 37 to respond to the camera main body CPU 27 with the reason for deletion designated for the image B.

  Of the plurality of reduced images 49 displayed on the rear monitor 21, the reduced image 49 of the image B that is the target of the inquiry item 46 is displayed larger than the other reduced images 49. Further, the reduced image 49 of the image A that has already been inquired is grayed out, and further, the reduced image 49 is scrolled downward and framed out from the rear monitor 21 in order to start an inquiry for the next reduced image 49.

  Further, in the example shown in the figure, an image that has been designated for deletion and temporarily stored is displayed as a reduced image 49. However, the camera body CPU 27 may display the captured image designated to be deleted on the entire rear monitor 21 and display the inquiry item 46, the option 47, and the like superimposed on the captured image. Thereby, the captured image is displayed in a large size, and it becomes easy for the user to grasp the details of the image.

  Referring to FIG. 11 again, the camera body CPU 27 that issued the inquiry checks whether or not there is a response from the user (step S402). Here, when there is no response from the user, the camera body CPU 27 may determine that the user does not intend to respond when the predetermined threshold time has elapsed, and end the confirmation mode. (Step S402: NO).

  On the other hand, when there is a response from the user (step S402: YES), the camera body CPU 27 deletes each of the photographic image data to be deleted due to the photographic conditions at the time of photographic that generated the photographic image data. Is received by the option 47 selected by the user (step S403).

  Further, the camera main body CPU 27 adjusts the initial value of the shooting condition of the camera system 1 in accordance with the received selection item of the reason for deletion (step S404). As a result, the initial value related to the shooting conditions of the camera system 1 is changed so that the occurrence of the reason for deletion is reduced.

  The adjusted settings may be stored in association with the type of the photographing lens 3 attached to the camera body 2 when the photographing data is photographed, for example. Thereby, even when the photographic lens 3 is replaced, the adjusted setting value related to the focus is stored, and when the photographic lens 3 is mounted again, the photographic condition reflecting the user's intention is reset.

  Next, the relief mode may be executed for the captured image whose reason for deletion has been confirmed (step S405). The relief mode will be described later with reference to other drawings.

  The captured image data of the image A for which the response to the inquiry has been completed is completely erased from the secondary recording medium 34 as already described (step S406). As can be seen from FIG. 6, the camera body CPU 27 confirms the reason for deletion as long as a deleted image whose deletion reason has not been confirmed remains and the camera system 1 is not ready for photographing (step S103: NO). Repeat (step S110).

  In other words, the confirmation mode is interrupted when the camera system 1 is ready for photographing. However, when the shooting system of the camera system 1 is released, the confirmation mode is activated again.

  As described above, in the confirmation mode, the series of controls shown in FIG. 11 is executed. However, the camera body CPU 27 may inquire the reason for deletion hierarchically to the user. That is, the camera body CPU 27 may further inquire about the state of focus when, for example, focus is selected as the reason for deletion.

  FIG. 13 is a diagram showing an example of the contents displayed on the rear monitor 21 when making a hierarchical inquiry about the reason for deletion. If, for example, focus is selected in the first stage of inquiry, the camera body CPU 27 causes the rear monitor 21 to display a second stage inquiry relating to focus.

  In the example shown in the drawing, an option 47 for inquiring how the focus is not matched is displayed for the reason for deletion of the selected focus. The user moves the selection frame 48 to any one of the options 47 with the cross button 36 and presses the decision button 37 to indicate the reason for deleting the image B for the camera body CPU 27. Notify

  Thus, by making the inquiry in two stages, the camera body CPU 27 can grasp the reason for deleting the photographed image data with higher accuracy. That is, even if the captured image data B is different from the user's intention, if the subject is in focus, the camera body CPU 27 cannot sufficiently grasp that the cause of deletion is in focus.

  However, if it is determined that the cause of deletion is the focus and the focus shift is nearer or farther than the intended position, the camera body CPU 27 can grasp the user's intention to shoot. Therefore, the camera body CPU 27 can set an offset with respect to the output of the focus detection sensor 11 to bring the in-focus position closer to the position intended by the user. Further, it is possible to cope with a focus shift caused by aging of the taking lens 3 or the like.

  Also, if you accept the option 47 that the cause of the deletion is in focus but the focus cannot be shifted either way, rather than interpreting it as a cause of camera shake or subject blur rather than focusing. Also good. In such a case, the camera body CPU 27 sets a program for increasing the shutter speed.

  FIG. 14 is a diagram exemplifying a list of inquiry contents as described above. For each item of hue and brightness in the option 47 shown in FIG. 6, a second-stage inquiry including a plurality of options 47 can be prepared, as in the second-stage inquiry shown in FIG. By making these inquiries to the user and accepting the user's selection, the camera body CPU 27 can extract the user's shooting intention that cannot be detected by the analysis of the shooting conditions.

  That is, for the hue, for example, by inquiring whether the color is a cold color or a warm color, the user's intention for the color that cannot be detected by the auto white balance can be known. Here, “it was a cold color” means that the photographed image looks pale when the color temperature of the photographed image is higher than the color temperature assumed by the user. Further, “it was a warm color” means that the captured image looks red when the color temperature of the captured image is lower than the color temperature assumed by the user. That is, the camera main body CPU 27 can accept a photographing intent relating to a color even from a user who does not have knowledge of the color temperature by the inquiry as described above. Note that the saturation, brightness, and the like of the photographed image may be directly specified according to the user's proficiency with respect to photographing.

  Furthermore, with regard to the brightness, it is possible to grasp the user's shooting intention that cannot be evaluated based on the suitability of automatic exposure by inquiring whether the user's shooting intention was dark or bright. Even if the user is performing exposure correction, the camera body CPU 27 can grasp whether the correction amount is appropriate for the user's intention, and can automatically adjust the correction amount.

  Still further, when the composition is selected by the user's operation of the cross button 36, the camera main body CPU 27 may have deleted unnecessary subjects due to the lack of the size of the main subject. The user may be inquired about the reason for deletion.

  For example, if “subject's facial expression” is selected as the inquiry item 46, and if the subject is not blinking or not smiling, it cannot be handled by changing the shooting conditions. In addition, it is not possible to cope with image processing on a captured image. Therefore, the camera body CPU 27 may display a guide screen that recommends the blink prevention mode or the smile detection mode of the camera system 1 when the guide mode is activated next (step S109 in FIG. 6).

  The blinking prevention mode means a function of securing a video without blinking by shooting a plurality of images at a slight time interval. Smile detection means a function of detecting a feature of a smile on an image from a through image in the live mode and executing shooting.

  Similarly, the camera body CPU 27 displays a guide screen that recommends the use of active D-lighting when the guide mode is activated (step S109 in FIG. 6) when the reason for deletion is overexposure or underexposure. May be.

  Needless to say, the inquiry item and the inquiry content are not limited to the above example. Inquiries may be made regarding a larger number of inquiries as long as the user's effort related to reception of the reason for deletion of the inquiry does not become excessive. As a result, the camera body CPU 27 can capture the user's shooting intention more precisely.

  Needless to say, the contents of the inquiry item and the display method are not limited to the illustrated example. For example, one captured image data to be inquired may be displayed on the entire rear monitor 21 and the inquiry item may be displayed superimposed on the captured image data. Also, icons, illustrations, etc. may be displayed other than characters.

  The confirmation of the reason for deletion described above may be executed one by one for a plurality of captured image data designated to be deleted. For example, a group of images captured within a predetermined time of about 5 to 10 minutes may be selected. As a group, one of them may be inquired as a representative. For example, the camera body CPU 27 may use an image taken last among a plurality of deletion designation images.

  Further, when making an inquiry to one group, it is desirable that the shooting targets of the shot image data included in the group are the same. Therefore, in addition to the grouping based on the photographing time described above, the classification may be performed based on the classification based on the face recognition and the similarity of the composition.

  FIG. 15 is a flowchart showing a control procedure executed by the camera body CPU 27 in the relief mode. In the rescue mode, the camera body CPU 27 determines whether or not the captured image to be rescued is a part of a group of grouped captured images, and other images belonging to the group remain without being deleted. (Step S501).

  When other images belonging to the same group as the relief target have not been deleted (step S501: NO), the camera body CPU 27 determines that the user has already acquired a captured image to be left for the photographing target of the group. To end the relief mode. On the other hand, if all images belonging to the same group have been deleted (step S501: YES), the camera body CPU 27 determines whether or not the deletion reason confirmed for the captured image can be recovered (step S501: YES). Step S502).

  That is, as already described, when the overexposure or underexposure in the photographed image is the reason for deletion, the gradation of the image cannot be recovered in the area where overexposure, clearance, or underexposure occurs. Also, when the subject's facial expression or blinking is the reason for deletion, the subject's facial expression cannot be corrected. Therefore, the remedy mode is terminated without attempting correction for the photographed image deleted for such a deletion reason (step S502: NO).

  On the other hand, when the reason for deletion can be handled by image processing such as color, brightness, composition, etc. (step S502: YES), the camera body CPU 27 instructs the image processing control circuit 25 to perform image processing in order to eliminate or reduce the reason for deletion. (Step S503). Further, the camera body CPU 27 displays the corrected captured image on the rear monitor 21 and presents the correction result to the user (step S504).

  Next, the camera body CPU 27 inquires of the user whether or not to re-save the corrected image (step S505). When the user instructs not to save (step S505: NO), the camera body CPU 27 ends the relief mode. On the other hand, when the user instructs to save (step S505: YES), the repair mode is ended after the corrected image is saved (step S506).

  As described above, by executing the relief mode, it is possible to rescue a captured image once designated for deletion without re-imaging. Next, image processing in the relief mode will be specifically exemplified.

  When the reason for deletion of a certain photographed image relates to color, the camera body CPU 27 displays a hue adjustment setting screen on the rear monitor 21. Accordingly, the user can change the color of the captured image by operating the cross button 36. Similarly, the camera body CPU 27 may guide the execution of white skin adjustment, skin beautification adjustment for adjusting skin color saturation, and the like. Further, it may be proposed to convert the captured image into a monochrome image, a sepia image, or the like.

  The camera body CPU 27 displays the captured image after the image processing on the rear monitor 21 as a corrected image (step S504), and inquires of the user whether or not to save (step S505). When the reason for deletion of the user is eliminated or reduced by the image processing, the user instructs to save the corrected image (step S505: YES). This makes it possible to relieve a captured image once deleted without re-imaging.

  If the reason for deletion of a certain photographed image is related to the composition, and if the main subject is a small reason for deletion, the camera body CPU 27 performs image processing control to enlarge the main subject. The circuit 25 is caused to execute. In this case, the camera body CPU 27 may enlarge the image enlargement ratio in accordance with the operation amount of the cross button 36. Moreover, when the touch panel sensor is laminated | stacked on the back monitor 21, you may make it select an expansion location and an expansion rate with a touch panel sensor.

  If the reason for deletion of a certain captured image is related to the composition, and if the detailed reason for deletion is that an unnecessary subject is shown in a large size, the camera body CPU 27 performs image processing control for trimming the image. The circuit 25 is caused to execute. In this case, the camera main body CPU 27 may allow the user to specify the trimming range by the cross button 36. Alternatively, the camera body CPU 27 may cause the image processing control circuit 25 to execute processing for blurring an unnecessary subject in the image.

  When the reason for deletion of a certain photographed image is related to the composition, and when overexposure or underexposure is a detailed deletion reason, the camera body CPU 27 performs γ curve correction for suppressing overexposure or underexposure. The image processing control circuit 25 may be executed. As already explained, overexposure and underexposure cannot be repaired, but they can be made inconspicuous. Whether or not to save such a corrected image is displayed on the rear monitor 21 (step S504) and left to the user's judgment (step S505).

  In the above embodiment, the case where a plurality of image deletions are performed has been described in detail. However, the above embodiment may be applied to deletion of one image. Moreover, in the said Example, the camera system 1 which is a lens interchangeable single-lens reflex camera was demonstrated as an example. However, the above control can be applied not only to a compact digital camera, a mirrorless single-lens camera and a video camera but also to a mobile phone.

  FIG. 16 is a diagram schematically illustrating a personal computer 60 that executes an imaging condition setting program. The personal computer 60 is connected to the camera system 1 via a cable 61.

  The personal computer 60 has a display 62, a main body 63 and a keyboard 64. The main body 63 loads a display control unit that performs predetermined image processing and displays an image on the display 62, a recording medium that stores captured image data through communication with the camera system 1, and a program to be executed. An optical drive 65 or the like used in some cases is provided. Further, the main body 63 includes a processor that executes the loaded program.

  The personal computer 60 as described above operates as an image processing apparatus that executes the control procedure shown in FIG. 15 by reading a program. Further, the personal computer 60 can receive photographed image data from the camera system 1 via the cable 61 and can process it.

  Therefore, the user can use the larger display 62 and keyboard 64 to select and delete the captured image and respond to the inquiry about the reason for deletion. The setting value of the imaging condition adjusted by receiving the user's response can be set and executed in the camera system 1 via the cable 61, for example. Thus, the subsequent shooting can be performed under shooting conditions reflecting the user's intention.

  The captured image data and setting information between the camera system 1 and the personal computer 60 may be transferred via the cable 61 as shown in the figure, or may be wireless communication. Alternatively, the photographic image data and the setting information may be delivered by delivering a secondary recording medium in which the photographic image data is stored. The execution of the shooting condition setting program is not limited to the camera system 1 and the personal computer 60, and may be executed at a store or an online print service facility.
