The designation of the image processing condition for each photographing mode is designated by the number by assigning a number in advance to the image processing condition corresponding to each photographing mode, for example.

  Image data generation processing executed in the digital still camera 10 according to the present embodiment will be described with reference to FIG. FIG. 4 is a flowchart showing a processing routine of image data generation processing executed in the digital still camera 10 according to the first embodiment.

  This embodiment is executed by the control circuit 16 (CPU 161). When the photographer sets the exposure, shooting mode, etc., and the shutter is released, the CPU 161 forms an image on the photoelectric conversion element of the image acquisition circuit 12 via the optical circuit 11, and sets the analog / digital converter. Then, digital image data is generated (step S100).

  The CPU 161 reflects the shooting conditions set at the time of shooting through the image quality correction circuit 13 and executes image quality adjustment at the time of shooting on the RGB image data (step S110). In the image quality adjustment at the time of shooting executed at this time, for example, the image quality correction circuit 13 adjusts the tone curve (γ curve) according to the set exposure amount and applies the adjusted tone curve to the image data. Adjust the brightness. The image quality correction circuit 13 corrects the white balance of the image data by executing a color balance adjustment process on the image data in accordance with the set light source.

  After completing the correction process on the image data, the CPU 161 converts the RGB data into YCbCr data using the known conversion matrix via the image quality correction circuit 13. Next, the CPU 161 compresses the image data converted into YCbCr data through the compression circuit 14 in accordance with the JPEG format, and obtains image data in the JPEG format (step S120).

  The CPU 161 acquires image processing control information GI from the ROM 162 according to the shooting conditions (step S130). More specifically, parameters as image processing conditions at the time of executing image processing are acquired based on the exposure amount, shutter speed, white balance (light source), and the like set as shooting conditions. In addition, when a shooting mode that defines image processing conditions suitable for a specific shooting scene such as a night view, a sunset view, or a person is selected, a number corresponding to the selected shooting mode is acquired as the image processing control information GI. The

  The CPU 161 describes the acquired image processing control information GI in the header portion (application marker segment APP) of the image data in JPEG format, stores the image data GD in the memory card MC, and ends this processing routine. That is, the image processing control information GI and the image data GD are associated with each other and stored in the memory card MC.

  With reference to FIGS. 5 to 7, the editing process of the image processing control information GI in the first embodiment will be described. FIG. 5 is a flowchart showing an editing processing routine of the image processing control information GI in the first embodiment. FIG. 6 is an explanatory diagram showing an edited image of the image processing control information GI in the digital still camera 10 according to the first embodiment. FIG. 7 is an explanatory view showing another display image of the image processing control information GI displayed when editing the image processing control information GI in the first embodiment.

  In accordance with a user instruction, the CPU 161 displays a file name (data name) of the image data GD or a preview image of the image data GD on the liquid crystal display 19. When the user selects image data GD desired to edit the image processing control information GI via the selection / determination button 18, the CPU 161 selects the image data selected by the user from the memory card MC (step S200).

  The CPU 161 displays the image processing control information GI associated with the selected image data on the liquid crystal display 19 as shown in FIG. 6 (step S210). In FIG. 6, the shooting mode is displayed as the image processing control information GI, and the currently set shooting mode is “night scene”. For example, the shooting mode may be set to “night view” on the previous day, and shooting may be performed in the daytime the next day without returning the shooting mode to “standard”. Conventionally, even after the user notices that the shooting mode is not appropriate after shooting, the user cannot edit (change) the shooting mode. As a result, originally, image processing corresponding to the “standard” shooting mode must be performed, but image processing corresponding to the “night scene” shooting mode has been performed by the personal computer PC, the printer 20, or the like. .

  According to the digital still camera 10 of the first embodiment, when the user notices that the shooting mode is not appropriate after shooting, the user can edit (change) the shooting mode, and as a result, It is possible to appropriately specify image processing conditions in the personal computer PC, the printer 20, and the like. Since the image processing control information GI is information for designating image processing conditions for the image data, the image data GD remains original until the image processing is executed. Therefore, if the erroneously set photographing mode can be changed to an appropriate photographing mode, image processing in the personal computer PC, the printer 20 and the like can be made appropriate.

  As the image processing control information GI, the contents shown in FIG. 7 may be displayed on the liquid crystal display 19 instead of the shooting mode in FIG.

  The CPU 161 stands by until the editing of the image processing control information GI ends (step S220: No). When the editing of the image processing control information GI ends (step S220: Yes), whether or not the image processing control information GI has been changed. Is determined (step S230). The CPU 161 determines that the editing of the image processing control information GI has ended when an editing end instruction is input from the user via the selection / determination button 18.

  If the CPU 161 determines that the image processing control information GI has not been changed (step S230: No), the processing routine ends. When the CPU 161 determines that the image processing control information GI has been changed (step S230: Yes), the CPU 161 updates the image processing control information GI described in the image data GD (step S240), and ends this processing routine. To do.

  Whether the image processing control information GI has been changed is determined based on the change flag, for example, when a value of any parameter of the image processing control information GI is changed. For example, the image processing control information GI may be updated by overwriting the image processing control information before the change with the image processing control information after the change, or, if appropriate, the parameter value of the image processing control information before the change. And difference information between the parameter value of the changed image processing control information may be written.

The same constituent elements as those of the digital still camera 10 according to the present invention are provided, and the description of each constituent element is omitted by giving the same reference numerals.

  The CPU 161 displays a file name (data name) of the image data GD or a preview image of the image data GD on the liquid crystal display 19 in accordance with a user instruction. When the user selects image data GD desired to edit the image processing control information GI via the selection / determination button 18, the CPU 161 reads the image data selected by the user from the memory card MC onto the RAM 163 (step S300). ).

  The CPU 161 acquires the image processing control information GI associated with the selected image data (step S310), and displays the acquired image processing control information GI on the liquid crystal display 19 (step S320). The CPU 161 applies the acquired image processing control information to the image data GD stored in the RAM via the image processing circuit 15, and, as shown in FIG. 9, the display image of the image data GD after the image processing and The applied image processing control information GI is displayed on the liquid crystal display 19 (step S330). In FIG. 9, the shooting mode is displayed as the image processing control information GI, and the currently set shooting mode is “night scene”. It goes without saying that the contents shown in FIG. 7 may be displayed on the liquid crystal display 19 as the image processing control information GI.

  The CPU 161 determines whether or not the image processing control information GI has been changed (step S340). If it is determined that the image processing control information GI has been changed (step S340: Yes), the image processing on the image data GD is performed. The control information GI is updated, the updated image processing control information GI is displayed on the liquid crystal display 19, and then the image data GD to which the updated image processing control information GI is applied is displayed on the liquid crystal display 19. (Step S320). Whether or not the image processing control information GI has been changed is determined, for example, by the method described in the first embodiment.

  If the CPU 161 determines that the image processing control information GI has not been changed (step S340: No), the CPU 161 waits until the editing of the image processing control information GI is completed (step S360: No). When the editing of the image processing control information GI ends (step S360: Yes), the CPU 161 determines whether or not an output request for the image data GD has occurred (step S370). The CPU 161 determines that the editing of the image processing control information GI has been completed when an editing end instruction is input from the user via the selection / determination button 18, and an output request for the image data GD is output when the output request instruction is input. It is determined that it has occurred.

  If the CPU 161 determines that an output request has not occurred (step S370: No), the process routine ends. If the CPU 161 determines that an output request has occurred (step S370: Yes), the CPU 161 applies the image processing control information GI updated via the image processing circuit 15 to the image data GD, and sends it to the printer 20 or the like. (Step S380), and this processing routine ends.

  As described above, according to the digital still camera 10 of the second embodiment, the image processing control information GI is obtained while confirming the image data GD to which the image processing control information GI is applied (image processing has been performed). Can be edited. Therefore, the parameter value of the image processing control information GI can be changed to an appropriate value.

  In addition, since image data GD subjected to image processing by applying the image processing control information GI can be output, even in a personal computer PC, printer 20 or the like that cannot interpret and use the image processing control information GI, An image of image data to which the image processing control information GI is applied can be output.

  When an image of the image data GD to which the image processing control information GI is applied is displayed on the liquid crystal display 19, for example, the result of applying the image processing control information GI to the thinned image data GD and thumbnail image data May be displayed. Since the liquid crystal display 19 can display an appropriate image even at a resolution lower than that of the printer (during printing), it is required for image processing while maintaining the image quality of the display image at an appropriate level. The load on the CPU 161 can be reduced.

  Further, when image processing is executed by the CPU 161 via the image processing circuit 15, the image data is analyzed, for example, statistical values of parameters related to image quality are taken, and the statistical values and parameters related to each image quality are preliminarily determined. Automatic image quality adjustment processing using the reference value may be executed. Needless to say, the image processing control information GI can be reflected in the automatic image quality adjustment processing.

Third embodiment:
A digital still camera according to a third embodiment will be described with reference to FIGS. FIG. 10 is a flowchart showing an imaging condition editing process routine in the third embodiment. FIG. 11 is an explanatory diagram schematically showing a file structure of image data that can be used in the third embodiment. FIG. 12 is an explanatory view showing a display image of shooting time information displayed when editing shooting time information in the third embodiment. Note that terms such as file structure, data structure, and storage area in this embodiment mean an image of a file or data in a state where the file or data is stored in the storage device.

  The digital still camera according to the third embodiment has the same constituent elements as those of the digital still camera 10 according to the first embodiment except that the shooting conditions are edited instead of the image processing control information GI. Since it is provided, description of each component will be omitted by giving the same reference numerals.

  First, the structure of the image data GD1 used in the third embodiment will be described. The image data GD1 includes JPEG image data and an application marker segment APP that stores auxiliary information for the JPEG image data. In the application marker segment APP (IFD), a tag is used to specify each piece of information, and each piece of information is sometimes called by a tag name. The application marker segment APP shown in FIG. 11 includes a tag (area) for storing shooting time information SI (Exif information) describing shooting conditions, and thumbnail image data.

  In the shooting time information SI, shooting conditions at the time of shooting shown in FIG. 12 are described. The shooting time information includes both shooting conditions set by the user such as an exposure program and shooting scene type, and shooting conditions set in the digital still camera 10 during auto shooting such as shutter speed and exposure time.

  Next, photographing information editing processing executed in the digital still camera 10 will be described. In accordance with a user instruction, the CPU 161 displays a file name (data name) of the image data GD1 or a preview image of the image data GD1 on the liquid crystal display 19. When the user selects image data GD1 for which the shooting time information SI is desired to be edited via the selection / determination button 18, the CPU 161 selects the image data selected by the user from the memory card MC (step S400).

  The CPU 161 displays the shooting time information SI associated with the selected image data on the liquid crystal display 19 (step S410). For example, the shooting scene set as the shooting time information SI may be set to “night view”, and shooting may be performed in the daytime without returning the shooting scene to “standard”. Conventionally, even after the user notices that the shooting scene is not appropriate after shooting, the user cannot edit (change) the shooting scene. As a result, image processing in the personal computer PC, printer 20, etc. may not be performed properly.

  According to the digital still camera 10 according to the third embodiment, after the shooting, when the user notices that the shooting scene is not appropriate, the user can edit (change) the shooting scene, and as a result, In the personal computer PC, the printer 20, etc., image processing based on an appropriate shooting scene can be executed.

  The CPU 161 waits until the editing of the shooting time information SI is completed (step S420: No). When the editing of the shooting time information SI is completed (step S420: Yes), it is determined whether or not the shooting time information SI is changed. (Step S430). The CPU 161 determines that the editing of the shooting time information SI is completed when an editing end instruction is input from the user via the selection / determination button 18.

  If the CPU 161 determines that the shooting time information SI has not been changed (step S430: No), this processing routine ends. If the CPU 161 determines that the shooting time information SI has been changed (step S430: Yes), the CPU 161 updates the shooting time information described in the image data GD1 (step S440), and ends this processing routine. The update of the shooting time information SI may be performed, for example, by overwriting the shooting time information before the change with the shooting time information after the change or, if appropriate, the parameter value of the shooting time information before the change and the changed value. You may make it add the difference information with the parameter value of information at the time of imaging | photography.

Fourth embodiment:
A fourth embodiment will be described with reference to FIG. FIG. 13 is a flowchart showing a processing routine of image processing control information editing processing in the fourth embodiment. In the first and second embodiments, the image processing control information GI associated with the image data GD selected by the user is edited after shooting. However, in the fourth embodiment, the image processing control information GI is edited. The image processing control information GI stored in advance in the ROM 162 is edited regardless of the data GD.

  In the present embodiment, description will be given using the above-described shooting mode as the image processing control information GI. The CPU 161 displays image processing control information GI (shooting mode) on the liquid crystal display 19 in accordance with a user instruction. When the user selects image processing control information GI desired to be edited via the selection / determination button 18, the CPU 161 selects and acquires a shooting mode as the image processing control information GI selected by the user (step S500). . Subsequently, the CPU 161 displays on the liquid crystal display 19 the values of the respective parameters constituting the shooting mode as the image processing control information GI selected and acquired by the user (step S510).

  The CPU 161 waits until the editing of the image processing control information GI ends (step S520: No). When the editing of the image processing control information GI ends (step S520: Yes), the image processing control information GI is changed. It is determined whether it has been done (step S340). Since the determination method for editing the image processing control information GI by the CPU 161 and the determination method for determining whether the image processing control information GI has been changed have already been described in the second and second embodiments, the description thereof will be omitted.

  If the CPU 161 determines that the image processing control information GI has been changed (step S530: Yes), the CPU 161 updates the image processing control information GI on the image data GD (step S540), and ends this processing routine.

  If the CPU 161 determines that the image processing control information GI has not been changed (step S540: No), the CPU 161 ends this processing routine without updating the image processing control information GI. When an output request instruction is input, it is determined that an output request for image data GD has occurred.

  As described above, according to the digital still camera 10 of the fourth embodiment, the image processing control information GI stored in the ROM 162 can be changed (edited) regardless of the image data GD. Therefore, the image processing control information GI, in particular, the values of parameters constituting the shooting mode can be changed in advance according to the user's preference. As a result, the image processing control information GI collectively changed can be described (associated) with the image data without changing the image processing control information GI in units of the image data GD each time.

Other examples:
