[Overall operation of digital camera]
FIG. 3 is a flowchart for explaining the overall operation of the digital camera 100 of the present embodiment.

  When the power switch 72 is operated to turn on the power, the system control unit 50 initializes flags, control variables, and the like in step S301. Subsequently, in step S302, management processing relating to the file recorded on the recording medium 200 is started. Here, the presence / absence of a reproduction target directory, the presence / absence of a reproduction target image file, the total number of images in the recording medium 200, the minimum file number, the maximum file number, the total file number, the total time stamp, the total file size, the total number of files, etc. And stored in the system memory 52.

  Next, in steps S303, S305, and S307, the system control unit 50 determines the set position of the mode switch 60. If the still image recording mode has been set, the process proceeds from step S303 to step S304 to execute still image recording mode processing. If the mode switch 60 is set to the moving image recording mode, the process proceeds to step S306 through steps S303 and S305, and the moving image recording mode process is executed. If the mode selector switch 60 is set to the playback mode, the process proceeds to step S308 through steps S303, S305, and S307, and the playback mode process is executed. The reproduction mode process in step S308 will be described later with reference to FIG.

  If another mode has been set, the process proceeds to step S309, and the system control unit 50 executes a process according to the selected mode. Other modes include, for example, a transmission mode process for transmitting a file stored in the recording medium 200, and a reception mode process for receiving a file from an external device and storing it in the recording medium 200.

  After executing the process corresponding to the mode set by the mode switch 60 among steps S304, S306, S308, and S309, the process proceeds to step S310. In step S310, the system control unit 50 determines the set position of the power switch 72. If the power switch 72 is set to power on, the process returns to step S303. On the other hand, if the power switch 72 is set to power off, the process proceeds from step S310 to step S311 and the control unit 50 performs an end process. The termination process includes, for example, the following process. That is, the display of the image display unit 28 is changed to the end state, the lens barrier 102 included in the optical system 101 is closed to protect the imaging unit, and parameters, setting values, and setting modes including flags and control variables are nonvolatile. The data is recorded in the memory 56, and the power supply to a portion where power supply is unnecessary is cut off. When the termination process of step S311 is completed, this process is terminated, and the power is turned off.

[File structure]

[Still Image Recording Mode Processing (S304)]
FIG. 5 is a flowchart showing still image recording mode processing in step S304 of FIG. Note that the still image recording mode process shown in FIG. 5 is terminated by an interrupt process or the like when the mode switch 60 is switched to another mode or when the power switch 72 is set to OFF. And

When starting the still image recording mode, the system control unit 50 determines the shooting mode in step S501. To confirm the shooting mode,
(1) Acquire the shooting mode at the end of the previous still image recording mode from the non-volatile memory 56 and store it in the system memory 52, or
(2) When the operation unit 70 is operated by the user and a shooting mode setting is input, the setting and input shooting mode is stored in the system memory 52. Here, the shooting mode is a mode realized by combining a shutter speed, an aperture value, a flash emission state, a sensitivity setting, a user interface, and the like suitable for the shooting scene and the skill level of the user.

  In step S <b> 502, when the shooting mode is determined in step S <b> 501, the system control unit 50 subsequently performs through display that displays the image data from the imaging unit 22. Subsequently, in step S503, the system control unit 50 determines whether the remaining capacity of the power supply unit 30 configured by a battery or the like using the power supply control unit 80, the presence / absence of the recording medium 200, and the remaining capacity are problems in the operation of the digital camera 100. It is determined whether or not there is. If there is a problem, in step S504, a predetermined warning is displayed by an image or sound using the image display unit 28, and the process returns to step S501.

  If there is no problem in the state of the power supply unit 30 and the recording medium 200, it is determined in step S507 whether the first shutter switch signal SW1 is on or off. If it is determined in step S507 that SW1 is ON, the process proceeds to step S508. In step S508, the distance of the subject is measured for shooting, an optimum focus setting is performed, and photometry of the object scene is performed to determine an optimum exposure place.

  In steps S509 and S510, the ON / OFF states of the first shutter switch signal SW1 and the second shutter switch signal SW2 are determined. If the second shutter switch signal SW2 is turned on while the first shutter switch signal SW1 is turned on, the process proceeds from step S509 to step S511. When the first shutter switch signal SW1 is turned off, the process returns from step S510 to step S501. Further, while the first shutter switch signal SW1 is ON and the second shutter switch signal SW2 is OFF, the processes of steps S509 and S510 are repeated.

  When the second shutter switch SW2 is pressed, in step S511, the system control unit 50 sets the display state of the image display unit 28 from the through display to the fixed color display state.

[photograph]
In step S512, the system control unit 50 executes photographing processing including exposure processing and development processing. In the exposure process, the subject image that has passed through the optical system 101 is converted into image data by the imaging unit 22. The obtained image data is temporarily written in the system memory 52 and cached. In the development process, the system control unit 50 reads data cached in the system memory 52, performs various processes on the image data, generates an image file together with various related data such as a shutter speed, and the recording medium. 200 records an image file. Details of this recording process will be described later with reference to FIG.

[Review start]
Next, in step S513, the system control unit 50 performs a REC review display of the image data obtained by the photographing process on the image display unit 28. Rec review is a process of displaying image data on the image display unit 28 for a predetermined time (review time) before recording on a recording medium after shooting of a subject for confirmation of a shot image.

[Record]
After the REC review display, in step S514, the system control unit 50 executes a recording process start request for writing the image data obtained by the photographing process to the recording medium 200 as an image file. This recording process is executed asynchronously with the photographing process. That is, even if image data that has already been shot is waiting to be written to the recording medium 200, the next shooting can be performed if there is an empty area in the system memory 52. Details of the recording process will be described later with reference to FIG.

[SW2 retention review]
When the recording process in step S514 ends, in step S515, the system control unit 50 determines the ON / OFF state of the second shutter switch signal SW2. If the second shutter switch signal SW2 is ON, the determination in step S515 is repeated, and the process waits for the second shutter switch signal SW2 to be OFF. During this time, the display of the REC review is continued. That is, when the recording process in step S514 is completed, the REC review display on the image display unit 28 is continued until the second shutter switch signal SW2 is released. With this configuration, the user can carefully check the captured image data using the REC review by continuing to fully press the shutter button 61.

  After the user has taken a picture with the shutter button 61 fully pressed, the process proceeds from step S515 to step S516 when the fully pressed state is released by releasing the shutter button 61 or the like.

[Change Attributes]
In step S516, the operation unit 70 determines whether or not there is a user instruction for changing an attribute by operation. If it is determined here that an attribute change instruction has been given, the process advances to step S517 to perform attribute change processing. Details of this recording process will be described later with reference to FIG.

  When the attribute change process in step S517 is completed, the process returns to step S501. If it is determined in step S516 that there is no attribute change instruction, the process advances to step S517.

[Minimum review]
In step S517, the system control unit 50 determines whether a predetermined review time has elapsed. If the review time has elapsed, the system control unit 50 proceeds to step S518. In step S518, the system control unit 50 returns the display state of the image display unit 28 from the REC review display to the through display state. With this process, after the captured image data is confirmed by the REC review display, the display state of the image display unit 28 is automatically switched to a through display state in which the image data from the imaging unit 22 is sequentially displayed for the next shooting. become.

  In step S519, the system control unit 50 determines whether the first shutter switch signal SW1 is ON / OFF. If the first shutter switch signal SW1 is ON, the process proceeds to step S509. If the first shutter switch signal SW1 is OFF, the process proceeds to step S501. return. That is, when the shutter button 61 is half-pressed (the first shutter switch signal SW1 is ON), the system control unit 50 prepares for the next shooting (step S509). On the other hand, if the shutter button 61 has been released (the first shutter switch signal SW1 is OFF), the system control unit 50 ends a series of shooting operations and returns to the shooting standby state (step S501).

[Shooting Process (S512)]
Details of step S512 of the above-described still image recording flow (FIG. 5) will be described with reference to FIGS. 8 and 10A. FIG. 8 is a flowchart for explaining the operation of the photographing process of the digital camera 100 of this embodiment. FIG. 10A is a diagram showing an arrangement of data cached in the system memory 52 of image configuration data generated in the photographing process of the digital camera 100 of the present embodiment.

  In step S801, the system control unit 50 executes an exposure process. In step S802, the subject image input in the exposure process is converted into electronic data by the imaging unit 22, and is written into the system memory 52 as RAW image data. In step S803, header 2 (1002) as attribute information is created and developed. This is, for example, the second application marker described in FIG. Next, in step S804, the RAW image data in the system memory 52 is subjected to various image processing such as development, converted into image data 1003 of a format to be recorded on the recording medium 200, and recorded in the system memory 52. . In step S805, the image data is analyzed, and header 1 (1004) as attribute information is created and developed. This is, for example, the first application marker described in FIG. 4 and includes creation and development of thumbnail images. .

  FIG. 10A shows an image diagram of a captured image storage area of the system memory 52 at the time of the processing. 1001 is an image diagram of the captured image storage area of the system memory 52. The attribute information 2 developed in step S803, the next 1003 is the image data developed in step S804, and the next 1004 is the attribute information developed in step S805. 1. Similarly, 1005, 1006, and 1007 are data developed at the time of the next shooting, and this data is written to the recording medium 200 by a recording process asynchronously with the shooting.

  At the time of shooting, the arrangement order of the image data held in the digital camera and the attribute information as the related information is as described above. In particular, the header 1 portion including the thumbnail image data is recorded after the image data. .

[Recording process (S514)]
Details of step S514 of the above-described still image recording flow (FIG. 5) will be described with reference to FIGS. FIG. 9 is a flowchart for explaining the operation of the recording process of the digital camera 100 of this embodiment. FIG. 10B is a diagram showing an arrangement on the recording medium 200 of the image file generated in the recording process of the digital camera 100 of the present embodiment.

  In step S901, the system control unit 50 determines whether there is an unrecorded image. This can be determined by whether image data is stored in the system memory 52 shown in FIG. If it is determined that there is no unrecorded image, the process returns to step S901 to wait for unrecorded image storage. If it is determined that there is an unrecorded image, the process proceeds to step S902. In step S902, the recording image file name is determined, and thereafter the image file is recorded in the order of the file structure shown in FIG. In step S903, the header portion is first written. In step S904, an image data part is added to the already written header part to complete the image file.

  In FIG. 10B, reference numeral 1010 denotes an image of the recording medium 200, and reference numeral 1011 denotes an image file written in the processing. Similarly, reference numeral 1012 denotes an image file in which the next photographed image is stored. As a result of the above processing, the image configuration data described in the photographing processing is changed from the image configuration data arranged in the system memory 52 in the order in which the arrangement order is different from the image file data structure shown in FIG. You can export an image file to have a structure. That is, the image data is recorded after the header including the thumbnail image data and recorded as an image file.

  When the writing of the image file is completed, the written image configuration data is registered in step S905. As a result, the system memory 52 area is required for subsequent shooting, or when the empty area is insufficient, the area is preferentially discarded and the area is reused. At this time, by preferentially discarding the image data portion having a large amount of data, the next image can be captured and the header portion can be prepared for reuse.

[Reproduction Mode Processing (S308)]
Details of step S308 in the above-described overall operation flow (FIG. 3) will be described with reference to FIG. FIG. 6 is a flowchart for explaining the operation in the playback mode of the digital camera 100 of the present embodiment. Note that the playback process shown in FIG. 6 is terminated by an interrupt process or the like when the mode switch 60 switches to another mode or when the power switch 72 is set to OFF.

  In step S <b> 601, the system control unit 50 acquires the latest image information from the recording medium 200. In step S602, the system control unit 50 checks whether or not the latest image information has been correctly acquired in step S601. If the latest image information has not been acquired, the process proceeds to step S603.

[Waiting for input when there is no image]
In step S603 and subsequent steps, the system control unit 50 enters an input waiting state when there is no image. In step S <b> 603, the system control unit 50 displays a message “No image” on the image display unit 28 to notify the user that there is no image data. Next, in step S604, the system control unit 50 waits for an operation input. The operation input here includes a button operated by the user, an operation on the battery cover, an event for notifying a decrease in power, and the like. If there is any input, the process proceeds to step S605, and processing corresponding to the operation input is performed. For example, when menu button operation is input without image data, a menu is displayed on the image display unit 28 so that the user can change settings.

  Note that the case where the latest image information cannot be acquired includes a state where there is no image, a state where the image information cannot be acquired due to media failure, and the like.

  If the latest image information can be acquired, it is determined that at least one image exists, and the process proceeds to step S1607.

[Latest image display processing]
In step S607, the system control unit 50 reads the latest image data from the recording medium 200 based on the latest image information acquired in step S601. In step S608, the system control unit 50 performs file analysis processing, and acquires image shooting information, attribute information, and the like in the read latest image data. In step S609, the system control unit 50 displays the read latest image data. Further, at this time, the photographing information and attribute information acquired in step S608 are also displayed. Further, according to the file analysis result in step S608, if it is known that the data is invalid, such as a part of the file is broken, an error display is also performed.

  In step S610, the system control unit 50 enters an input waiting state.

[Waiting for playback input in playback mode processing]
In step S610, the system control unit 50 checks whether there is an operation input by the user. The operation input here includes a button operation by a user, an operation for a battery cover, an event for informing a decrease in power, and the like. If there is no input, wait until there is an input. If there is any operation input, the process proceeds to step S611.

  In step S <b> 611, the system control unit 50 determines whether the operation input is an input of an image feed button included in the operation unit 70. If the operation input is an image advance button, the process advances to step S612, and the system control unit 50 reads the next display image. The image feed button is composed of a pair of buttons corresponding to the feed direction, and the next display image is read according to the feed direction corresponding to the operated button. Next, in step S613, the system control unit 50 performs file analysis processing on the image data read in step S612, and acquires image shooting information, attribute information, and the like in the read latest image data. In step S614, the system control unit 50 displays the image data read in step S612. At this time, shooting information, attribute information, and the like are displayed using the result of the file analysis processing in step S613. If it is determined that the data is invalid such as a part of the file is broken according to the file analysis result in step S613, an error display is also performed. When the display is completed, the process returns to the input waiting state in step S610.

  If it is determined in step S611 that the input is not an image advance button, the process proceeds to step S615.

  In step S615, the system control unit 50 checks whether the operation input is an operation of an attribute information change button included in the operation unit 70. If it is determined that the operation input is an attribute button, the process proceeds to the attribute change process in step S616. The attribute change process in step S616 will be described later with reference to FIG.

  If it is determined in step S615 that the button is not an attribute information change button, the process proceeds to S618. In step S618, processing corresponding to the operation input other than the above is performed. For example, image deletion, editing processing, switching to multi-playback, menu display using menu buttons, and the like. Multi-reproduction is a reproduction mode in which a plurality of reduced images of image data are displayed side by side on one screen of the image display unit 28.

  Each process in step S618 is executed, and then the process proceeds to step S619 to check for the presence of an image. If an image deletion process or the like is performed in step S618 and it is determined in step S619 that there is no image, the process advances to step S603 to perform a process when there is no image.

  If it is determined in step S619 that there is an image, the process returns to the input waiting state in step S610.

[About attribute change processing (S517, S616)]
Details of step S517 in the above-described still image recording flow (FIG. 5) and step S616 in the reproduction flow (FIG. 6) will be described with reference to FIGS. FIG. 7 is a flowchart for explaining the operation of attribute change processing of the digital camera 100 of this embodiment.

  In step S <b> 701, the system control unit 50 determines whether there is an image data of an image whose attribute is to be changed and a header as related data on the system memory 52 as a temporary storage unit. If it is determined that there is image data to be changed and related data, the process proceeds to step S702. In step S702, a target data block is selected. This is the selection of the target header data block after determining whether the editing target is in the header 1 part or the header 2 part of the image configuration data shown in FIG. Next, in steps S703 and S704, the syntax in the corresponding header data block is analyzed, the edit target position is calculated, and the attribute is changed. In step S705, it is confirmed whether the target image file exists in the recording medium. If YES in step S706, the flow advances to step S706 to calculate the file offset at the editing position from each size of the image configuration data in the system memory 52 and the file configuration shown in FIG. This file offset is address information indicating the position where the edited data is to be recorded in the image file. In this embodiment, the file offset is address information for specifying the position where the changed attribute is to be recorded.

  In the next step S707, the changed attribute information is written at the editing target recording position of the recording medium 200 calculated in S706, and the process ends. If it is determined in step S705 that there is no image file on the recording medium, that is, it is determined that the image configuration data expanded in the system memory 52 by the recording process has not been processed by the recording process. If so, exit the process.

  If it is determined in step S701 that there is no image data and related data to be changed in the system memory 52, the process proceeds to step 708. In step 708, the target image file is read from the recording medium 200 into the system memory 52. In step S709, an edit offset is calculated. Here, since the target image file is read with the file configuration shown in FIG. 4, the edit offset on the system memory 52 matches the edit file offset of the target file on the recording medium 200. In step S710, the edit offset on the system memory 52 is edited. In step S711, the same file offset is written to a file on the recording medium 200.

  As described above, since the address of the position to be edited in the image file on the recording medium is calculated based on the cache information at the time of shooting including the image data and the attribute information, the image file is not read at the time of editing. . Smooth editing operations are possible. In addition, even when the configuration data order of the cache information is different from the configuration data order on the image file, the address is calculated in consideration of the order of the image data and the related information and the configuration data size, so that the editing position can be performed only with the cache information. Can be calculated.

  In the above description, the attribute information changing process has been described. However, the present invention can also be applied to editing such as correction of image data.

  Although the present invention has been described above using a digital camera, the application of the present invention is not limited to this, and the present invention can be applied to an apparatus capable of reproducing an image, such as a printer, a mobile phone, or a mobile terminal.
