Description

  The present invention relates to an imaging apparatus such as a digital camera capable of reproducing an image, a control method for the imaging apparatus, a program, and a recording medium.

2. Description of the Related Art Conventionally, a digital camera that captures, records, and reproduces still images and moving images using a memory card having a solid-state memory element as a recording medium is commercially available. In such a digital camera, an image immediately after shooting is temporarily stored in a recording medium serving as a buffer, and then subjected to compression / encoding processing by a compression / decompression circuit and written to a memory card. For example, Patent Document 1 discloses a technique for temporarily storing a photographed image in a buffer and recording the image data temporarily stored in the buffer in a memory card during an idle time during which photographing or photographing mode setting is not performed. It is disclosed.
JP 2000-278777 A

  However, in a conventional digital camera, when the image data immediately after shooting temporarily stored in the buffer is switched from the shooting mode to the playback mode before recording to the memory card, the image is immediately played back and displayed. I couldn't do it. For example, in Patent Document 1, if the shooting mode is switched to the playback mode before the image data in the buffer is recorded on the memory card, the image display is set to the OFF state. The reproduction mode is not entered until the image stored in the buffer has been written to the memory card. Since this uses a compression / decompression circuit to compress the image stored in the buffer, among the recorded image files taken in the past, the image file of the same type as the image being compressed is decompressed. One reason is that we cannot. In other words, in the conventional digital camera, it is not possible to shift to the playback mode immediately after the end of shooting and quickly check images taken in the past.

  Therefore, the present invention can quickly check the outline of the same type of image taken in the past by switching to the playback mode even when compression of a specific type of image immediately after shooting or writing to a recording medium has not ended.

An example will be described.

[Overall Operation Process of Camera Body 100]
FIG. 4 is a flowchart for explaining the overall operation of the camera body 100 of the present embodiment.

  In FIG. 4, when the power switch 72 is turned on, the operation of the camera body starts, and in step S401, the system control circuit 50 first performs initialization for shooting and playback with the camera body 100.

  In step S402, it is determined whether or not the operation mode is the playback mode based on the position of the mode dial 60 and whether or not the playback button 66 has been operated. If it is determined that the current mode is the playback mode, the process proceeds to step S407, and playback mode processing is executed. The reproduction mode process will be described later with reference to FIG. When the reproduction mode process is terminated, the process returns to step S402. On the other hand, if it is determined that the playback mode is not selected, the process proceeds to step S403.

  In step S403, whether or not the operation mode is the still image shooting mode is determined based on the position of the mode dial 60, whether or not the playback button 66 is operated, whether or not the release button 114 is operated, and the like. If it is determined that the still image shooting mode is set, the process proceeds to step S408, the still image shooting mode process is executed, and the process returns to step S402. On the other hand, if it is determined that the still image shooting mode is not selected, the process proceeds to step S404.

  In step S404, it is determined whether or not the operation mode is the moving image shooting mode based on the position of the mode dial 60, whether or not the playback button 66 has been operated, and whether or not the release button 114 has been operated. If it is determined that the moving image shooting mode is set, the process advances to step S409 to execute moving image shooting mode processing. The moving image shooting mode process will be described later with reference to FIG. When the moving image shooting mode process ends, the process returns to step S402. On the other hand, if it is determined that the mode is not the moving image shooting mode, the process proceeds to step S405.

  In step S405, it is determined whether or not the operation mode is another mode. If the operation mode is other mode, the process proceeds to step S410, and other mode processing is executed. Examples of other modes include 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. Further, there are a menu display mode for confirming and changing various settings, a warning mode for displaying an abnormality of the camera body 100, and the like. When the other mode process in step S410 is completed, the process returns to step S402. On the other hand, if it is determined that it is not other mode processing, the process proceeds to step S406.

  In step S406, it is determined whether or not the processing of the camera body 100 is to be terminated by operating the power switch 72 or the like. If it is determined not to end, the process returns to step S402. If it determines with complete | finishing, it will progress to step S411, will perform the completion | finish process of a camera, and will complete | finish a process.

[Movie shooting mode processing]
The moving image shooting mode process described in step S409 in FIG. 4 will be described. FIG. 5 is a flowchart for explaining the moving image shooting mode processing of the present invention.

  In step S501, first, so-called live view display is performed in which the mirror 130 is retracted out of the imaging optical path, and an image captured by the image sensor 14 is displayed as a moving image on the image display unit 28 in almost real time.

  In step S502, it is determined whether or not an instruction to start moving image shooting has been issued by operating the release button 114 or the operation unit 70. If it is determined that the moving image shooting start instruction is not issued, the process proceeds to step S508. If it is determined that the moving image shooting start instruction is issued, the process proceeds to step S503.

  In step S503, a moving image recording process is performed (recording control). In the moving image recording process, for example, when the frame rate is set to 30 fps, the image data (moving image frame) obtained at 1/30 second intervals obtained by the image sensor 14 is temporarily stored in the buffer memory (memory 30). To do. Then, the image data (moving image frame) temporarily stored in the memory 30 is compressed by the moving image compression / decompression circuit 34, and the processed image data is stored in a write output buffer secured in the memory 30 ( Compression control). When the image data is stored in the write output buffer for a predetermined number of seconds, the image data is sequentially written from the write output buffer to the recording medium 200. At the same time, management information serving as header information of moving image data is recorded in the memory 52.

  In subsequent step S504, it is determined whether or not the operation mode has been switched from the moving image shooting mode to another mode based on the position of the mode dial 60 and whether or not the playback button 66 has been operated. If it is determined that the moving image shooting mode has been switched to another mode, the process proceeds to step S505.

  In step S505, the moving image shooting end process is started (recording control). In the end processing, the image data (moving image frame) temporarily stored in the buffer memory (memory 30) at this time is compressed by the moving image compression / decompression circuit 34, and the processed image data is secured in the memory 30. Stored in the written output buffer (compression control). Then, the compressed image data stored in the write output buffer is written to the recording medium 200. When the image data stored in the buffer memory (memory 30) has been written to the recording medium 200, the management information recorded in the memory 52 in step S503 is written (recorded) to the recording medium 200 as header information. Then, the moving image file on the recording medium 200 is closed to generate a moving image file. Further, a thumbnail file that forms a pair with the generated moving image file is generated.

  FIG. 6A shows an example of the generated moving image file. In the moving image file 601, for example, MVI_0005. The file name mov is given. Video stream data and audio stream data, which are the main body of moving image data, are recorded from the first half of the data sequence of the moving image file 601. In the second half of the moving image data string, the management information recorded during the end processing as described above is recorded as header information.

  FIG. 6B shows an example of a generated thumbnail file. A thumbnail file is a still image file that has a one-to-one correspondence with a moving image file, and any frame included in the moving image file is used as a thumbnail image (still image) for simply identifying the contents of the moving image file. It is a recorded file. In the present embodiment, the still image recorded in the thumbnail file is the first frame of a pair of moving images. The thumbnail file includes, for example, MVI_0005. The file name is THM. Thus, the same part as the part before the file name extension of the corresponding moving image file is attached to the part before the file name extension of the thumbnail file. The extension of the moving image file is “mov”, whereas the extension of the thumbnail file is “THM”. By using such a file name, the correspondence between the video file and the thumbnail file can be obtained by the part before the extension, and the extension can identify whether it is a video file or a thumbnail file. It is possible. The file format of the thumbnail file is an Exif (Exchangeable Image File Format) format. In addition to still image data (thumbnail image), various information, for example, shooting date and time, camera information at the time of shooting, and the like can be recorded in the Exif header portion. Furthermore, the Exif header part can be expanded and a unique data area can be provided. In the camera body 100 of the present embodiment, the management information of the moving image file described above is recorded in the user data area of the thumbnail file. When reproducing a moving image file, it is possible to reproduce the moving image file at high speed by referring to the management information recorded in the thumbnail file before expanding the moving image file. Resume information indicating in which frame the reproduction of the moving image file was completed last time is also recorded in the user data area of the thumbnail file.

  When the end process is started in step S505 in FIG. 5, the moving image shooting mode process is ended. In the present embodiment, the moving image shooting mode is ended before the end processing is completed, and the operation mode is determined by proceeding to step S402 in FIG. 4 while continuing the end processing. Then, at least in the playback mode, the transition can be made before completing the moving image shooting end processing.

  On the other hand, if it is determined in step S504 that the operation mode has not been switched from the moving image shooting mode to another mode, the process proceeds to step S506. In step S506, it is determined whether or not an instruction to end moving image shooting has been issued by operating the release button 114 or the operation unit 70. If it is determined that the moving image shooting end instruction has not been given, the process returns to step S503 to continue the moving image recording process. If it is determined that the moving image shooting end instruction has been issued, the process proceeds to step S507. In step S507, the moving image shooting end process is started. Since this end process is the same as the above-described step S505, description thereof is omitted. Without waiting for completion of the termination process in step S507, the process proceeds to step S508 while continuing the termination process. In step 508, it is determined whether or not the operation mode has been switched from the moving image shooting mode to another mode based on the position of the mode dial 60 and whether or not the playback button 66 has been operated. If it is determined that the mode has not been switched to another mode, the process returns to step S502 to continue the moving image shooting mode process. If it is determined that the moving image shooting mode has been switched to another mode, the moving image shooting mode process is terminated.

[Playback mode processing]
The reproduction mode process described in step S407 in FIG. 4 will be described. FIG. 7 is a flowchart for explaining the playback mode processing of the present invention.

  In step S701, the system control circuit 50 first identifies an image file to be reproduced from among the image files recorded in the recording medium 200 or the memory 30. Then, it is determined what is the type of image of the specified image file to be reproduced, that is, whether it is a still image file or a moving image file. In this embodiment, the image file to be reproduced first after the transition to the playback mode is the newest image file that has been completed as an image file (video file or still image file) before the transition to the playback mode. It is an image file. That is, for example, when the end process in the moving image shooting mode process of FIG. 5 described above is continued without being completed, the image file of the image shot before that is not the moving image being subjected to the end process. The newest image file is the image file to be reproduced. If it is determined that the image file to be reproduced is a still image file, the process proceeds to step S702. If it is determined that the image file to be reproduced is a moving image file, the process proceeds to step S703.

  In step S702, a still image file of an image to be reproduced is reproduced and displayed on the image display unit 28 (display control). The still image file is, for example, a JPEG file having an extension of “.jpg”, and the system control circuit 50 controls the still image file to be decompressed using the still image compression / decompression circuit 32 and reproduced and displayed. To do. Subsequently, the process proceeds to step S706 to wait for an operation from the user.

  On the other hand, in step S703, it is determined whether or not the end process (step S505 or S507) in the moving image shooting mode process of FIG. 5 described above has been completed. In this embodiment, the completion of the end process is determined by whether or not the data relating to the moving image that has been subjected to the end process has been written to the recording medium 200 (whether or not recording is in progress). If it is determined that writing has been completed, the process proceeds to step S704. If it is determined that writing has not been completed, the process proceeds to step S705.

  In step S704, control is performed so that the moving image file of the image to be reproduced is expanded / reproduced based on the resume information using the moving image compression / decompression circuit 34, and is displayed on the image display unit 28 as a still image (step S704). Display control). FIG. 8A shows a display example on the image display unit 28 at this time. The displayed image 801 is an image of a frame based on resume information in a moving image file (for example, MVI — 0731.mov). The number of seconds display 802 is a moving image file MVI_0731. It represents the time of the entire moving image recorded in mov. The icon 803 indicates that the video playback menu process can be entered by operating the SET button, as will be described later in step S708. Details of the image display processing from the moving image file will be described later with reference to FIG. Subsequently, the process proceeds to step S706 to wait for an operation from the user.

  In step S705, a thumbnail file corresponding to the moving image file of the image to be reproduced is searched, and the image of the thumbnail file is reproduced and displayed on the image display unit 28 (display control). FIG. 8B shows a display example on the image display unit 28 at this time. The displayed image 811 is an image file to be reproduced, for example, MVI_0731. If it is mov, the corresponding thumbnail file MVI_0731. A THM image (MVI — 0731.mov with the first frame as a still image) is reproduced. The number of seconds display 812 is a moving image file MVI_0731. It represents the time of the entire moving image recorded in mov. The icon 813 is displayed in gray out, and indicates that the moving image reproduction menu process cannot be performed even if the SET button is operated because the moving image shooting end process has not ended. In step S705, the moving image compression / decompression circuit 34 is in use because there is a moving image that is being finished. For this reason, it is impossible to perform decompression processing of other moving image files, and it is impossible to reproduce moving image files that are images to be reproduced. However, a still image file can be reproduced using the still image compression / decompression circuit 32. Therefore, the system control circuit 50 controls the corresponding thumbnail file to be decompressed using the still image compression / decompression circuit 32 and reproduced and displayed instead of the moving image file which is the image file to be reproduced. In this way, by displaying the thumbnail file image corresponding to the video file to be played back as representing the video file to be played back, even if there is a video that has not been finished, the mode can be quickly shifted to the playback mode process. Images can be displayed. When the process of step S705 is completed, the process proceeds to step S706 to wait for an operation from the user.

  In step S706, an operation from the user is awaited. When an operation from the user is accepted, the process proceeds to step S707.

  In step S707, it is determined whether the user operation is image feed. If it is image forwarding, the image to be reproduced according to the user's operation is set as the previous image or the next image, and the process returns to step S701. If it is determined that the image has not been fed, the process proceeds to step S708.

  In step S708, it is determined whether or not the user operation is a press of the SET button 117. In this embodiment, pressing of the SET button 117 is an operation instruction for the moving image file indicated by the displayed image. If it is determined that the SET button 117 has been pressed, the process advances to step S710 to perform a moving image playback menu process. The moving image reproduction menu process will be described later with reference to FIG. When the moving image playback menu process is completed, the process returns to step S706 to wait for the next operation from the user. On the other hand, if it is determined in step S708 that the SET button 117 has not been pressed, the process proceeds to step S709.

  In step S709, it is determined whether the user operation is an end operation. If it is determined that the operation is not an end operation, the process advances to step S711 to perform other processing according to the content of the user operation, return to step S706, and wait for the next operation from the user. If it is determined in step S709 that the user operation is an end operation, the playback mode process ends.

  In step S701, it is determined whether the specified image file to be reproduced is a still image file or a moving image file. If the image file is a moving image file, the process proceeds to step S703, and the end processing in the moving image shooting mode processing is completed. It was determined whether or not. This determination is made in step S703 because it is determined whether the end processing of the moving image shooting mode processing has been completed. If it is a moving image file, the process proceeds to step S703. That is, it is determined whether the type of the image to be determined whether or not the end process is being performed and the type of the image to be reproduced are the same.

  In step S703, it is determined whether or not the data relating to the moving image that has been subjected to the end process has been written to the recording medium 200. However, even if the writing has not ended, if the compression by the moving image shooting end processing has ended, the moving image compression / decompression circuit 34 is not in use and can be used for expanding the moving image file. However, even when the compression is completed and the moving image compression / decompression circuit 34 is not in use, a large moving image file can be used if there is no room in the communication line as long as data is being written from the memory 30 to the recording medium 200. There is a possibility that it cannot be read from the recording medium. Therefore, according to the present embodiment, it is determined whether or not data is being written to the recording medium 200 by the end process, and the moving image file is replaced with a thumbnail file without trying to read until the writing is completed. As a result, it is possible to display an image representing an outline of a moving image file to be reliably reproduced. Of course, if there is a sufficient capacity of the communication line from the memory 30 to the recording medium 200, the determination in step S703 in FIG. 7 may be a determination as to whether or not the compression of the moving image that has been subjected to the end processing has ended. The same applies to the determination in step S902 in FIG.

  In addition, when the thumbnail file image is reproduced and displayed in step S705, when the end processing in the moving image shooting mode processing is completed, the image of the moving image file that was originally to be reproduced is reproduced and the thumbnail file image is displayed. May be replaced. At this time, by referring to the management information of the corresponding moving image file recorded in the displayed thumbnail file, the image of the moving image file can be reproduced at higher speed.

[Video playback menu processing]
The moving image playback menu process described in step S710 in FIG. 7 will be described. FIG. 9 is a flowchart for explaining the moving image playback menu processing of the present invention.

  In step S901, it is determined whether the reproduction target image is a still image file. If the image being displayed on the image display unit 28 is an image representing a moving image file, that is, an image obtained by reproducing a moving image file or an image obtained by reproducing a thumbnail file, the reproduction target image is a moving image file. The process proceeds to S902. On the other hand, if the image being displayed on the image display unit 28 is an image representing a still image file with an extension of “jpg” or the like, the moving image playback menu process is terminated without doing anything.

  In step S902, it is determined whether or not the end process (step S505 or S507) in the moving image shooting mode process of FIG. 5 is completed. In the present embodiment, completion of the end process is determined based on whether or not the data relating to the moving image that has been subjected to the end process has been written to the recording medium 200. If it is determined that the writing has not been completed, the process proceeds to step S903. If it is determined that the writing has been completed, the process proceeds to step S904.

  In step S903, since the moving image file cannot be reproduced yet, the image display unit 28 displays that processing is in progress, returns to step S902, and waits for completion of writing.

  In step S904, the frame based on the resume information is reproduced from the moving image file to be reproduced and displayed on the image display unit 28 as a still image. Note that this processing may be omitted when the still image that has already been displayed is an image reproduced from a moving image file. Details of the image display processing from the moving image file will be described later with reference to FIG. Then, it progresses to step S905.

  In step S905, a moving image playback menu is displayed. FIG. 10 shows a display example of the moving image reproduction menu displayed on the image display unit 28. The still image 1001 is an image reproduced from the moving image file, and is an image of a specific frame (a frame based on the resume information in step S905) included in the moving image. In the video playback menu 1002, a plurality of operation icons for instructing playback of the video file to be played back are displayed. By operating the operation unit 70 and specifying any one of the operation icons. Various instructions can be given.

  In step S906, an operation from the user is awaited. When an operation from the user is accepted, the process proceeds to step S907.

  In step S907, it is determined whether or not the user operation is an operation icon related to reproduction of a moving image file among any of the operation icons included in the moving image reproduction menu. If the operation icon is designated, the process advances to step S910 to perform a moving image reproduction menu operation process. In the moving image reproduction menu operation processing, processing corresponding to the specified operation icon is performed. Processing that can be performed by designating an operation icon includes starting playback of a movie file to be played back, stopping a movie being played back, moving a movie frame, starting a movie, playing a movie slowly, and the like. When there is a change in the displayed image (frame) by any of these processes, the resume information stored in the memory 52 is updated. For example, this is a case where the image (frame) displayed before the start of playback changes due to the stop of the moving image being played back. When the moving image playback menu operation process is completed, the process returns to step S906 to wait for the next operation from the user. On the other hand, if it is determined in step S907 that the user operation is not the designation of an operation icon related to reproduction of a moving image file among any of the operation icons included in the moving image reproduction menu, the process proceeds to step S908.

  In step S908, it is determined whether the user operation is an end operation. If it is determined that the operation is not an end operation, the process advances to step S911 to perform other processing according to the content of the user operation, for example, volume operation processing, return to step S906, and wait for the next operation from the user. If it is determined in step S908 that the user operation is an end operation, the process proceeds to step S909.

  In step S909, the moving image reproduction menu process is terminated. The display of the moving image reproduction menu is terminated, and the resume information stored in the memory 52 is recorded (updated) in the user data area of the thumbnail file recorded on the recording medium 200 corresponding to the moving image file to be reproduced. When the end process is completed, the moving image playback menu process ends.

  In the end process of step S909, only the resume information in the thumbnail file is updated. However, the thumbnail images in the thumbnail file can be updated at the same time.

[Image display processing from movie files]
The image display processing from the moving image file described in step S704 in FIG. 7 and step S904 in FIG. 9 will be described. FIG. 11 is a flowchart for explaining image display processing from a moving image file according to the present invention.

  In step S1101, it is determined whether or not the resume information of the moving image file to be reproduced exists in the memory 52. If it is determined that it exists, the process proceeds to step S1103, and if it does not exist, the process proceeds to step S1102.

  In step S1102, resume information is read into the memory 52 from the user data area of the thumbnail file corresponding to the moving image file to be reproduced.

  In step S1103, the moving image file is controlled to be expanded using the moving image compression / decompression circuit 34, and the frame image indicated by the resume information in the memory 52 is cut out (extracted) from the moving image file. Subsequently, in step S1104, the image cut out is displayed on the image display unit 28, and the process ends.

  As described above, according to the present embodiment, during the moving image shooting end process, the display of the moving image file is substituted for the display of the thumbnail file corresponding to the moving image file. Thereby, even if the compression of the moving image file and the writing to the recording medium are not completed immediately after shooting, it is possible to quickly check the outline of the other moving image files shot in the past.

  The present invention is not limited to the above embodiment. When it is desired to check the outline of the file of the specific type of image during compression by the first compression / decompression circuit for the specific type of image, as a substitute, the file of the image of the other type corresponding to the other type The present invention includes any display that is expanded and displayed by the second compression / decompression circuit for the type of image. In the above embodiment, a specific type of image corresponds to a moving image, and other types of images correspond to still images. The compression / decompression circuit for a specific type of image corresponds to the compression / decompression circuit 34 for moving images, and the compression / decompression circuit for the other types of images corresponds to the compression / decompression circuit 32 for still images.

  For example, immediately after the still image shooting in the still image shooting mode, the mode is changed to the reproduction mode. If the compression of the still image has not been completed just after shooting, the still image compression / decompression circuit 32 is used. The image file cannot be played. Therefore, in this case, it may be determined whether the image to be reproduced is an image of the same type as the still image being compressed, that is, a still image file. If the file is a still image file, a moving image file corresponding to the still image file may be expanded and displayed by the moving image compression / decompression circuit 34, and may be substituted for the display of the still image file. In this case, a specific type of image corresponds to a still image, and the other type of image corresponds to a moving image. The compression / decompression circuit for a specific type of image corresponds to the still image compression / decompression circuit 32, and the compression / decompression circuit for the other type of image corresponds to the compression / decompression circuit 34 for moving image.

  As described above, according to the present invention, the display of a file of another type corresponding to the file of a specific type of image is used instead of the display of the file of a specific type of image. Thereby, even when compression of a specific type of image and writing to a recording medium are not completed immediately after shooting, an overview of a file of a specific type of image shot in the past can be quickly confirmed. That is, it is possible to quickly shift from the still image or moving image shooting mode to the reproduction mode and display the image.
