  The captured image 100 stored in the storage unit 7 includes an image data body 100a in a compressed state as shown in FIG. 1 for convenience, and shooting condition information added as attribute information to the image data body. 100b and imaging state information 100c.

  The shooting condition information 100b is information regarding various shooting conditions set at the time of shooting the already shot image 100, and is, for example, a shutter speed, an ISO sensitivity, an aperture value, and the like as illustrated in FIG. The shooting status information 100c is various information regarding the shooting status (shooting environment) at the time of shooting the already shot image 100. For example, as shown in FIG. 2B, the illuminance (brightness of the subject), weather, and shooting location. Of indoor / outdoor. Note that the shooting state information 100c is not added when the already shot image 100 is shot by a camera other than the digital camera 1, for example, and stored in the storage unit 7 of the digital camera 1 by an arbitrary method. In some cases.

  The operation unit 8 includes a plurality of operation keys such as a power key, a shutter key, and a mode switching key used for switching between a photographing mode and a reproduction mode which are basic operation modes of the digital camera 1.

More specifically, the communication unit 10 includes the already-captured image 100 stored in another device such as a server providing a social network service or a server providing a storage service for captured images. Receive. Image data (still image file) received by the communication unit 10 is also stored in the storage unit 7.

  The control unit 2 of the digital camera 1 stores data constituting a photographing situation estimation table used in a setting diversion mode described later in the ROM. As shown in FIG. 2C, the shooting situation estimation table 200 is a table showing a correspondence relationship between the type (one or more) of the shooting condition information 100b described above and the type of the shooting situation information 100c described above. That is, it is a table showing the correspondence between the contents of the shooting conditions set at the time of arbitrary shooting and the contents of the shooting conditions at the time of shooting that can be estimated when shooting is performed under the shooting conditions.

  Next, an operation according to the present invention of the digital camera 1 having the above configuration will be described. FIG. 3 is a flowchart showing the processing contents in the control unit 2 including processing in the set diversion mode provided in the digital camera 1. Here, the set diversion mode is provided in the digital camera 1 as a lower mode of the shooting mode, and the shooting condition to be set at the time of shooting is the already-shot image 100 selected by the user (hereinafter referred to as a selected image). This is an operation mode acquired using the shooting condition information 100b added to. That is, this is a mode for diverting the shooting condition information 100b added to an arbitrary shot image 100 as a shooting condition set at the time of shooting.

  As shown in FIG. 3, for example, the control unit 2 starts processing when the power of the digital camera 1 is turned on, and first checks whether or not the currently set operation mode is the shooting mode. (Step S1).

  When the operation mode is not the shooting mode but the playback mode (step S1: NO), the control unit 2 performs initial setting of the playback mode for the processing in the playback mode and displays the shot image on the display unit 6 ( Step S2). The captured image displayed here is, for example, a captured image that was last displayed in the playback mode immediately before the power is turned off, that is, a predetermined captured image.

Next, the control part 2 confirms the presence or absence of a mode change operation by the user, and if there is no mode change operation (step S3: NO), further confirms the presence or absence of another operation (step S4).
The operation content confirmed by the control unit 2 in the process of step S4 is, for example, an operation for instructing image forwarding, image enlargement, and slidesee display. Then, when there is another operation (step S4: YES), the control unit 2 executes a predetermined process according to the operation (step S5), and then checks again whether or not there is a mode change operation (step S3). .

  On the other hand, when the shooting mode is set immediately after the power is turned on (step S1: YES), and when there is a mode change operation from the reproduction mode to the shooting mode (step S3: YES), the control unit 2 takes the shooting mode. In addition to performing the initial setting of the shooting mode for the processing in, the live view display on the display unit 6 is started (step S6). Accordingly, for example, a live view image as shown in FIG. 7A is displayed on the display unit 6.

  Thereafter, it is confirmed whether or not the above-described set diversion mode is selected as a lower mode of the shooting mode by the user. When the set diversion mode is selected (step S7: YES), the following processing is executed.

  First, the control unit 2 causes the user to select an arbitrary already-captured image to be processed in the process for acquiring the shooting conditions (step S8). In step S8, the control unit 2 displays a plurality of already-captured images 100 stored in the storage unit 7 on the display unit 6 so that they can be selected in a forward order or displayed as a list in a selectable manner. Select an already shot image.

  Alternatively, the control unit 2 connects to the Internet 500 via the communication unit 10 in response to a user instruction, receives the already-captured images 100 existing on the Internet 500, and displays the received plurality of already-captured images 100 on the display unit 6. The user can select a desired already-captured image by displaying the images in a sequential manner so that the images can be selected or by displaying the list in a selectable manner.

  At this time, the user is allowed to select a pre-photographed image that approximates a desired photo-exposure to be obtained by the subsequent photographing, for example, a pre-photographed image having an atmosphere according to preference.

  Next, the control unit 2 acquires the shooting condition information 100b added to the already shot image selected by the user (hereinafter referred to as a selected image) (step S9), and further displays the current shooting status information. Obtain (step S10). FIG. 7B is a diagram conveniently showing an example of an already captured image selected by the user.

  The shooting situation information acquired by the control unit 2 in such processing is information of a type that can be detected directly or indirectly using the image sensor of the imaging unit 5 as a sensor. That is, in the process of step S10, the control unit 2 acquires (detects) shooting status information such as the illuminance of the subject and the shooting location (indoor or outdoor) based on the image data of the subject supplied from the imaging unit 5. When detecting the shooting location, the control unit 2 specifies the type of light source by the same processing as the AWB control at the time of shooting, and determines whether the shooting location is indoor or outdoor from the specified type of light source.

  Next, the control unit 2 confirms whether or not the shooting status information 100c is added to the selected image. If the shooting status information 100c is not added (step S11: NO), the processing of steps S12 to S14 described later is performed. If it is executed and added (step S11: YES), the processing of step S15 to step S19 described later is executed.

  First, a process when the shooting status information 100c is not added to the selected image will be described. FIG. 6A is an explanatory diagram showing the processing contents in that case.

  When the shooting status information 100c is not added to the selected image, the control unit 2 refers to the shooting status estimation table 200 described above based on the shooting condition information acquired from the selected image as shown in FIG. The shooting situation when the selected image is shot is estimated (step S12). That is, the control unit 2 confirms the contents of the shooting situation corresponding to the specific contents of the kind of shooting condition (one or more) shown in the shooting situation estimation table 200 in the shooting condition information acquired from the selected image. To do.

  Next, the control unit 2 specifies the first difference A between the shooting situation information estimated in the process of step S12 and the shooting situation information indicating the current shooting situation acquired in the process of step S10 ( Step S13). That is, the control unit 2 specifies different types of shooting situations in both shooting status information.

  Thereafter, based on the first difference A, the control unit 2 corrects the shooting condition information 100b acquired in the process of step S9 (step S14). In the process of step S14, the control unit 2 determines that, for example, the first difference A, that is, the types of shooting situations different from each other in the shooting situation information are shooting locations, and the shooting location of the estimated selected image is indoors. On the other hand, when the current shooting location is outdoors, the white balance in the shooting condition information 100b acquired in step S9 is corrected to the white balance at the time of outdoor shooting.

  In addition, in the process of step S14, when there are a plurality of types of shooting condition information corresponding to the first difference A, the control unit 2 starts from the shooting condition information of a higher priority level determined in advance as necessary. Correct in order. Here, as shown in FIG. 2A, the priority of each type in the shooting condition information 100b is higher as the type of shooting condition information has less influence on the shooting result.

  Therefore, for example, when the first difference A is the illuminance (subject brightness) and the current illuminance is lower or higher than the estimated illuminance of the selected image, the shooting condition acquired in the process of step S9. When the ISO sensitivity is corrected first among the information related to the illuminance in the information (shooting conditions), that is, the shutter speed, the aperture value, and the ISO sensitivity, and it exceeds the correction range, the ISO sensitivity is set to the correction range. Correct to the limit, and then correct the aperture value.

  That is, in the processing from step S12 to step S14, when the shooting situation when the selected image (already shot image) is shot and the current shooting situation are different, shooting condition information at the time of shooting the selected image is obtained. It is corrected according to the current shooting situation.

  As a result, the shooting condition information obtained after correction can be obtained shooting condition information suitable for shooting the subject to be shot, that is, a shooting result in a good state, and a selected image according to the user's preference. This is imaging condition information that can obtain an imaging result having an approximate atmosphere.

  Further, when correcting the shooting condition information acquired from the selected image, if there are a plurality of types of shooting condition information corresponding to the first difference A, a type having a higher priority order determined in advance as necessary. Corrections are made in order from the shooting condition information. Even in this case, the corrected shooting condition information becomes shooting condition information that can obtain a shooting result in a good state suitable for shooting a subject more reliably.

  Next, processing when the shooting status information 100c is added to the selected image will be described. FIG. 6B is an explanatory diagram showing the processing contents in that case.

  When the shooting status information 100c is added to the selected image, as shown in FIG. 3, the control unit 2 acquires the shooting status information added thereto from the selected image (step S15), and acquires the acquired shooting status. A second difference B between the information and the shooting status information indicating the current shooting status acquired in the process of step S10 is specified (step S16). In other words, the control unit 2 specifies the actual difference between the actual shooting situation when the selected image is shot and the current shooting situation, which are different types of shooting situations in both shooting situation information.

  Next, similarly to the process of step S12, the control unit 2 refers to the above-described shooting condition estimation table 200 based on the shooting condition information acquired from the selected image, and the shooting situation when the selected image is shot. Is estimated (step S17). In other words, in the process of step S17, the control unit 2 captures the selected image when it is assumed that the capturing condition when the selected image is captured is set according to a general standard according to the capturing situation at the time of capturing. Guess the shooting situation.

  Subsequently, the control unit 2 specifies the third difference C between the estimated shooting situation and the shooting situation indicated by the shooting situation information added to the selected image acquired in the process of step S15 (step S18). ). The third difference C is different from the case where the shooting condition when the selected image is shot is generally set according to the standard according to the shooting situation at the time of shooting, and is intentionally changed by the photographer, for example. In this case, for example, a difference in shooting situation occurs when the exposure is set to be higher (brighter) than normal or set to be lower (darker) than normal.

  Thereafter, the control unit 2 captures the imaging condition information 100b acquired in the process of step S9 based on the second difference B specified in the process of step S16 and the third difference C specified in the process of step S18. Is corrected (step S19). In the process of step S19, the control unit 2 corrects the shooting condition information 100b acquired in the process of step S9 based on the second difference B in the same procedure as the process of step S14 described above, and then the corrected shooting condition. The information is further corrected based on the third difference C in the same procedure as the processing in step S14 described above.

  Thereby, also in the processing of step S15 to step S19, if the shooting situation when the selected image (already shot image) is shot and the current shooting situation are different, the shooting condition information at the time of shooting the selected image Is corrected according to the current shooting situation. In addition, in the shooting condition information obtained after the correction, if the shooting condition when the selected image is shot is intentionally changed by the photographer, that is reflected.

  As a result, the shooting condition information obtained after correction can be obtained shooting condition information suitable for shooting the subject to be shot, that is, a shooting result in a good state, and a selected image according to the user's preference. This is imaging condition information that can obtain an imaging result having an atmosphere that more reliably approximates.

  Further, when correcting the shooting condition information 100b acquired from the selected image, if there are a plurality of types of shooting condition information corresponding to the second difference B and the third difference C, it is determined in advance as necessary. Corrections are made in order from the higher-priority shooting condition information. Even in this case, the corrected shooting condition information becomes shooting condition information that can obtain a shooting result in a good state suitable for shooting a subject more reliably.

  As described above, after correcting the shooting condition information 100b added to the selected image by the processing of step S12 to step S14 or the processing of step S15 to step S19, the control unit 2 continues to perform the following steps shown in FIG. Execute the process.

  That is, the control unit 2 displays the live view image based on the corrected shooting condition information on the display unit 6 and displays the mode on the screen (step S20). In the process of step S20, the control unit 2 subjects the image data of the subject supplied from the imaging unit 5 to image processing with the content according to the corrected shooting condition information, so that the subject being displayed as a live view image is displayed. A display image similar to the image generated when shooting is performed according to the corrected shooting condition information is displayed on the display unit 6 as a live view image. That is, a live view image in which the corrected shooting condition information is reflected is displayed. Note that the display image does not have to be the same as the actual shooting result, and may be one that allows the user to confirm the effect when the corrected shooting condition information is set at the time of shooting.

  The mode display in the process of step S20 is for clearly indicating that the set diversion mode is currently set and the live view image is an image in which the corrected shooting condition information is reflected. In other words, this is for making the user identify the effect of the corrected shooting condition information, and is performed by OSD display. FIG. 7C is a diagram illustrating an example of a live view image and mode display displayed on the display unit 6 in the process of step S20. Therefore, the user can confirm with the live view image, before the photographing, what kind of photographing result information can be obtained at the time of photographing.

  Subsequently, the control unit 2 checks whether or not there is an instruction (key operation) that the user needs to correct the shooting condition information being reflected in the live view image, and there is an instruction that the correction is necessary. In this case (step S21: YES), the user is made to select the type of shooting condition information that should be excluded as the shooting condition at the time of shooting from the corrected shooting condition information (step S22).

  In the process of step S22, the control unit 2 causes the display unit 6 to display a selection screen for selecting the type of shooting condition information as shown in FIG. Lets you select the type of information. Thereafter, the control unit 2 performs correction to exclude the type of shooting condition information selected by the user from the shooting condition information being reflected in the live view image (step S23).

  As a result, when the shooting condition information automatically corrected by the process of step S14 or the process of step S19 described above is not suitable for the intended shooting, the user manually sets the shooting condition information according to the intended shooting. Can be further corrected. That is, the user's will can be reflected in the photographing condition information obtained after correction.

  For example, the brightness is adjusted by the ISO sensitivity having a higher priority than the aperture value in the automatically corrected shooting condition information, despite the fact that it is desired to obtain a shooting result in which noise is as inconspicuous as possible. When the shooting condition information is such that noise is conspicuous in the shooting result, the ISO sensitivity may be selected as the type of shooting condition information to be excluded as a shooting condition at the time of shooting.

  In addition, for example, when flash photography is not possible, if there is a flash in the automatically corrected shooting condition information, there is a flash as the type of shooting condition information that should be excluded as a shooting condition at the time of shooting. Is selected, it is possible to obtain shooting condition information such that a desired shooting result can be obtained by adjusting no flash, shutter speed, aperture value, ISO sensitivity, and white balance.

  Then, the control unit 2 causes the display unit 6 to display a live view image based on the shooting condition information after the correction in the process of step S23, and performs mode display on the screen (step S24). In addition, the specific process of the control part 2 at this time is the same as that of the case of the process of step S20. FIG. 7E is a diagram illustrating an example of a live view image and mode display displayed on the display unit 6 in the process of step S23. Therefore, the user can confirm with the live view image, before the photographing, what kind of photographing result information can be obtained at the time of photographing.

  As a result, the user can check the photographing result obtained when photographing is performed by applying the photographing condition information with the content excluding the kind of photographing condition information selected by the user.

  Thereafter, the control unit 2 checks whether or not there is an instruction to save the shooting condition information being reflected in the live view image at that time (step S25). Note that if there is no instruction from the user that correction is necessary after the live view display and mode display in the process of step S20 described above (step S21: NO), the control unit 2 immediately It is checked whether there is an instruction to save the shooting condition information being reflected in the view image (step S25).

  When there is an instruction to save the shooting condition information (step S25: YES), the control unit 2 performs a process for saving the shooting condition information currently reflected in the live view image (step S26). In the storage process, the control unit 2 adds, for example, the shooting condition information that reflects the image currently displayed as the live view image to the image and saves the image as a normal image for storing the shooting condition information. The captured image 100 is stored in the storage unit 7 in an identifiable state. As a result, the shooting condition information acquired in the set diversion mode at the time of arbitrary shooting can be used at the time of subsequent shooting.

  Then, after the process of step S26, the control unit 2 returns to the process of step S7 described above. When there is no instruction to save the shooting condition information (step S25: NO), the control unit 2 immediately proceeds to the process of step S7 described above. Returning, if the set diversion mode is selected again (step S7: YES), the processing after step S8 described above is repeated.

  On the other hand, the control unit 2 performs a storage shooting condition mode prepared in advance as a lower mode of the shooting mode after performing the processing after step S8 described above or while performing the live view display before performing it. If it is selected by the user, the process proceeds to FIG. 5 (step S7: NO, step S27: YES), and the following processing is performed.

  First, the control unit 2 causes the user to select shooting condition information that has been stored in advance by the storage process in step S26 described above as shooting condition information to be set during shooting (step S28). In the process of step S28, the control unit 2 causes the display unit 6 to display one or a plurality of the above-described storage conditions of the shooting condition information stored in the storage unit 7 in a selectable order or display a selectable list. By doing so, the user is made to select a desired storage image, that is, photographing condition information. Thereafter, the control unit 2 starts live view display reflecting the shooting condition information selected by the user (step S29), and returns to the process of step S7.

  When the shutter key is operated (pressed) at any point in time during live view display (step S7: NO, step S27: NO, step S30: YES), the control unit 2 records. The photographing process for acquiring the image data is executed (step S31).

  The shooting process executed by the control unit 2 in step S31 includes the shooting condition information described above as a live view image, that is, the shooting condition information acquired in steps S12 to S14 and the processes in steps S15 to S19. When the live view image in the reflected state is displayed, it is a shooting process according to the shooting condition information. The shooting conditions executed by the control unit 2 in step S31 are AE control and AWB when a live view image in a normal state that does not reflect the shooting condition information described above is displayed as a live view image. This is imaging processing according to imaging condition information obtained by control or the like.

  Thereafter, the control unit 2 compresses the image data acquired in the photographing process in step S31, adds various attribute information, and stores it in the storage unit 7 as a still image file (step S32).

  Further, when there is an operation other than the shutter key during the live view display (step S30: NO, step S33: YES), the control unit 2 executes a predetermined process according to the operation. (Step S34), it is confirmed again whether the set diversion mode has been selected (Step S7). Note that the operation content confirmed by the control unit 2 in the process of step S33 is a zoom setting or the like.

  As described above, according to the digital camera 1 of the present embodiment, the user simply selects an image that approximates the desired shooting result from the existing shooting images, and the desired shooting result can be obtained in a good state. Can be obtained easily and reliably.
