  DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. In the drawings, the same or corresponding parts are denoted by the same reference numerals.

  FIG. 1 is a circuit diagram showing a configuration of a camera apparatus according to an embodiment of the present invention. 1 includes a lens module 100, a CCD / CDS / ADC module (CCD: Charged Coupled Device, CDS: Analog Digital Converter), a camera signal processing circuit 102, and a JPEG compression / decompression process. Circuit 103, memory circuit 104, memory card 105, hard disk drive 106, MPEG compression / decompression processing circuit 107, video / OSD circuit (OSD: On Screen Display) 108, LCD (Liquid Crystal Display) driver 109, LCD 110, and CPU (Central Processing Unit) 111 is provided.

  The lens module 100 forms an optical image of the subject and captures it in the CCD / CDS / ADC module 101. The CCD / CDS / ADC module 101 receives the formed optical image by the CCD, and generates a digital signal that is A / D converted through the CDS / ADC.

  The camera signal processing circuit 102 performs predetermined image processing on the digital signal input from the CCD / CDS / ADC module 101 to generate moving image data and still image data. The generated moving image data and still image data are temporarily stored in the memory circuit 104. In the present embodiment, the lens module 100, the CCD / CDS / ADC module 101, and the camera signal processing circuit 102 function as image data generation means of the present invention.

  The JPEG compression / decompression processing circuit 103 generates compressed still image data by compressing still image data received from the camera signal processing circuit 102. The JPEG compression / decompression processing circuit 103 decompresses the compressed still image data and reproduces the still image data. The compressed still image data and the reproduced still image data are temporarily stored in the memory circuit 104. In the present embodiment, the camera signal processing circuit 102 and the JPEG compression / decompression processing circuit 103 are built in the CPU 111.

  The MPEG compression / decompression processing circuit 107 generates compressed moving image data by compressing the moving image data received from the camera signal processing circuit 102. Also, the MPEG compression / decompression processing circuit 107 decompresses the compressed moving image data and reproduces the moving image data. The compressed moving image data and the reproduced moving image data are temporarily stored in the memory circuit 104.

  The memory circuit 104 is a work memory that temporarily stores the various data described above. In the memory circuit 104, a moving image file including compressed moving image data and a still image file including compressed still image data are formed in accordance with an instruction from the CPU 111.

  The memory card 105 records a moving image file and a still image file formed in the memory circuit 104. The memory card 105 is an external storage medium such as an SD memory card (Secure Digital memory card). Similarly, the hard disk drive 106 records a moving image file and a still image file formed in the memory circuit 104. Note that the CPU 111 determines whether the moving image file and the still image file formed in the memory circuit 104 are stored in the memory card 105 or the hard disk drive 106.

  The Video / OSD circuit 108 outputs the moving image data and still image data stored in the memory circuit 104 to the LCD driver 109. Further, the Video / OSD circuit 108 outputs data for screen adjustment for monitor adjustment to the LCD driver 109 during image display. In the present embodiment, the Video / OSD circuit 108 is built in the CPU 111.

  The LCD driver 109 converts the moving image data and still image data received from the Video / OSD circuit 108 into display signals suitable for the interface of the LCD 110. The LCD 110 displays a moving image and a still image corresponding to the moving image data or the still image data using the display signal output from the LCD driver 109. In the present embodiment, the LCD driver 109 and the LCD 110 function as image display means of the present invention.

  The CPU 111 operates as various means (imaging management information writing means, display control means, and image reproduction control means) that characterize the present invention in accordance with a program stored in a ROM (not shown). In addition, the CPU 111 performs input / output of signals with other components, and performs operation control of the entire camera apparatus 1 and control of each sequence.

(Outline of operation of camera device 1)
Next, an outline of the operation of the camera device 1 will be described. In the case of moving image shooting, light that has passed through the lens module 100 is received by the CCD in the CCD / CDS / ADC module 101, and is A / D converted through the CDS / ADC. A digital signal output from the CCD / CDS / ADC module 101 is converted into moving image data by image processing by the camera signal processing circuit 102 and stored in the memory circuit 104. The moving image data stored in the memory circuit 104 is compressed by the MPEG compression / decompression processing circuit 107 to generate compressed moving image data. This compressed moving image data is stored in the memory circuit 104.

  Similarly, in the case of still image shooting, still image data is generated by the lens module 100, the CCD / CDS / ADC module 101, and the camera signal processing circuit 102 and stored in the memory circuit 104. The still image data stored in the memory circuit 104 is compressed by the JPEG compression / decompression processing circuit 103 instead of the MPEG compression / decompression processing circuit 107 to generate compressed still image data. This compressed still image data is stored in the memory circuit 104.

  In the memory circuit 104, a still image file including compressed still image data is formed and a moving image file including compressed moving image data is formed in accordance with a command from the CPU 111. These still image files and moving image files are recorded in the memory card 105 or the hard disk drive 106.

  When still image shooting is performed during moving image shooting, still image data is being shot from moving image data generated by the lens module 100, the CCD / CDS / ADC module 101, and the camera signal processing circuit 102. Is taken out as still image data in a moving image and stored in the memory circuit 104. The subsequent processing is the same as in the case of still image shooting. Therefore, the still image file generated in the case of still image shooting during moving image shooting includes compressed still image data in moving image.

  At this time, each of the still image data and the moving image data stored in the memory circuit 104 is displayed on the LCD 110 via the LCD / driver 109 via the Video / OSD circuit 108.

  At the time of reproducing a still image, a still image file read from the memory card 105 or the hard disk drive 106 is temporarily stored in the memory circuit 104 and decompressed through the JPEG compression / decompression processing circuit 103 to obtain still image data or a still image in moving image. Data is played back. The reproduced still image data or moving image still image data is output to the LCD driver 109 via the Video / OSD circuit 108, and the corresponding still image is displayed on the LCD 110.

  On the other hand, when reproducing a moving image, the compressed moving image data read from the memory card 105 or the hard disk drive 106 is expanded via the MPEG compression / decompression processing circuit 107 instead of the JPEG compression / decompression processing circuit 103 to reproduce the moving image data. This is different from the playback of still images.

(Still image shooting during movie shooting)
Next, the operation of the camera device 1 when a still image is shot during moving image shooting will be described. FIG. 2 is a flowchart showing the operation of the camera device when a still image is shot during moving image shooting, and FIG. 3 is a diagram showing the configuration of the still image file or moving image file. FIG. 3A shows the configuration of a still image file, and FIG. 3B shows the configuration of a moving image file.

  When a conventional camera device captures a still image during moving image shooting, it performs a still image shooting process and then returns to the moving image shooting state.

  In the camera apparatus 1 of the present embodiment, as shown in FIG. 2, when shooting a still image during moving image shooting (step S401) (step S402), the CPU 111 operates as shooting management information writing means, and still image shooting is performed. After the process (step S403), that is, still image data in moving image captured during moving image shooting of still image data from moving image data generated by the lens module 100, the CCD / CDS / ADC 101, and the camera signal processing circuit 102 After that, shooting management information indicating correspondence between moving image data and moving image still image data is generated.

  After that, the shooting management information is information that indicates the correspondence between the moving image data and the still image data in the moving image and that can specify the generation timing of each of the moving image data and the still image data in the moving image. The image unique number, the still image shooting time, the still image thumbnail information, the moving image unique number, the moving image chapter number, and the like are included. The CPU 111 writes shooting management information in the still image file. Specifically, as shown in FIG. 3A, the CPU 111 writes the still image unique number in the header portion of the still image file and also writes the original moving image file information being shot (step S404). At this time, the CPU 111 also writes shooting management information in the moving image file. Specifically, as shown in FIG. 3B, the CPU 111 writes a still image unique number and a still image shooting time in addition to the moving image unique number in the header portion of the moving image file (step S405).

  As a result, it is possible to prevent erroneous recognition even if the file name is changed or deleted. Note that the still image file and the moving image file may be managed by the mutual file names. Further, it is more desirable to use all of the above information and file names in combination.

  Next, when a moving image chapter is added (step S406), as shown in FIG. 3B, the CPU 111 writes moving image chapter information (for example, a moving image chapter number) in the header of the moving image file (step S407). . When the writing of information is completed, the moving image shooting end determination (step S408) is performed. If the moving image shooting is not ended, the process returns to the shooting state (step S402) to prepare for the next still image shooting. On the other hand, when the movie shooting is ended by pressing the Stop button or the like, the movie shooting is ended (step S409).

(Video playback and still image playback)
Next, the operation of the camera device 1 when a moving image and a still image are reproduced will be described. FIG. 4 is a flowchart illustrating the operation of the camera device when a moving image and a still image are reproduced, and FIG. 5 is a diagram illustrating a configuration of the moving image file or the still image file. FIG. 5A shows the configuration of a moving image file, and FIG. 5B shows the configuration of a still image file. FIG. 6 is a diagram showing transition of the display screen by the LCD, and FIG. 7 is a diagram showing a list display screen of still image display and chapter display by the LCD.

  In the conventional camera device, it is determined whether the image selected in the playback mode is a still image or a moving image, and a still image display or a moving image display is performed according to the determination result. Further, when the Wide key is pressed, only thumbnail display is performed.

  In the camera device 1 of the present embodiment, as shown in FIG. 4, when the Wide key is not operated in the playback mode (step S501) (step S502) and the process proceeds to the next image (step S503), the CPU 111 performs display control means. In the header of the corresponding still image file, it is searched whether there is information indicating that a still image was shot during moving image shooting, that is, whether shooting management information exists (step S504). When the original moving image unique number D simultaneously shot in the header of the still image file exists, the CPU 111 causes the LCD 110 to display the moving image unique number D together with the still image file as shown in the display 601 in FIG. S507), the process returns to step S502. At this time, instead of the moving image unique number D, information regarding the moving image such as the file name of the moving image file or the moving image chapter number may be displayed.

  On the other hand, if there is no shooting management information in the still image file, the CPU 111 searches for information on still images taken simultaneously in the moving image file, that is, whether there is shooting management information (step S505), and in the header of the moving image file. If there is a still image unique number or the like of a still image that has been shot simultaneously, the process proceeds to step S513. On the other hand, if there is no still image unique number or the like in the header of the moving image file (step S505) and it is further determined that it is not a moving image file but a still image (step S506), the display 602, 603 in FIG. As shown in FIG. 4, normal still image display is performed (step S508), and when it is determined that the image is not a still image but a moving image (step S506), normal moving image display is performed (step S509). .

  Next, as shown in displays 601, 602, and 603 of FIG. 6, when the Wide key is pressed in the normal display state (step S 501) (step S 502), the CPU 111 operates as an image list display control unit and displays It is searched whether the image that has been processed is a still image and there is shooting management information in the header of the still image file (step S510). Next, when there is no moving image unique number in the header of the still image file and the displayed file is a moving image and there is no still image unique number in the header (step S512), as shown in the display 604 of FIG. Then, a normal thumbnail list display is performed (step S526).

  On the other hand, if the displayed image is a still image and the moving image unique number is in the header of the still image file in step S510, the CPU 111 searches for the existence of the original moving image file in the header information. (Step S511) When the original moving image file exists, the process proceeds to Step S513 as a still image in moving image, and when the original moving image file does not exist, the normal thumbnail list display (Step S526) is performed. If the displayed file is a moving image and the still image unique number is included in the header in step 512, the process proceeds to step 513.

  Next, the CPU 111 reads out a still picture unique number from the header of the moving image file as shown in FIG. 5A (step S513), and the corresponding still picture as shown in FIG. 5B based on the still picture unique number. The image file is searched, and the corresponding moving image chapter is searched from the moving image chapter (step S514), and it is searched whether there is a still image file simultaneously shot with the moving image file (step S515). If there is a still image file simultaneously shot with the moving image file, the CPU 111 reads out the corresponding still image file (step S516). On the other hand, if there is no still image file simultaneously shot with the moving image file, the CPU 111 searches for whether or not the moving image chapter information exists in the moving image file (step S523), and the moving image file includes the moving image chapter information. In this case, the corresponding thumbnail information is read (step S524), and if there is no moving picture chapter information, the process proceeds to step S517.

  Next, the CPU 111 repeats the processes of steps S514, S515, S516, S523, and 524 until all still image files and all moving image chapters indicated by the shooting management information of the moving image file are read. After reading all still image files and moving image chapters (step S517), if reading all still image files and all moving image chapters fails (step S518), it is assumed that no still image was shot during moving image shooting. Regardless, the process proceeds to normal thumbnail display (step S526). In other cases, the CPU 111 arranges the read still image files and moving image chapters in time series based on the shooting management information and associates them with the time table (step S519), which are shown in displays 605, 606, and 607 in FIG. As described above, the display mode shifts to the list display mode of the still image display for specifying the moving image and the still image data in the moving image and the chapter display for specifying each moving image chapter (step S520). Details of the list display mode of the still image display and the chapter display will be described later.

  When the Wide key is pressed in this list display mode, as shown in a display 604 in FIG. 6, the display shifts to a normal thumbnail list display (step S526). When the process proceeds to the next image (step S522), the next image of the last still image taken simultaneously with the moving image is selected, and the process returns to step S504 (step S525).

  Next, a list display of the still image display Ba and the chapter display Bb will be described with reference to FIG. In FIG. 7, on the right side of the moving image display A, the still image display Ba by the still images B3 and B4 taken during the moving image shooting and the reproduced moving image are displayed, and the chapters by the moving image chapters B2 and B5 are displayed. Display Bb is displayed.

  In the present embodiment, still images B3 and B4 that are displayed as still images and moving image chapters B2 and B5 that are displayed as chapters are combined and displayed side by side in order of shooting time. The moving image chapters B2 and B5 and the still images B3 and B4 have different frame colors, and are displayed so as to be distinguishable from each other. Further, in the moving image display A, a timing specifying display is displayed on the lower side based on the shooting management information. The timing specific display is a display that can specify the generation timing of the still image data in the moving image during the generation time of the moving image data. In this embodiment, the time bar C is displayed. In this time bar C, icons C2 and C5 representing the time of the moving picture chapters corresponding to each of the moving picture chapters B2 and B5 and the still pictures B3 and B4 and the icon C3 representing the shooting time of the still picture in order of the shooting time from the left , C4 are displayed. The moving image chapter icons C2 and C5 and the still image icons C3 and C4 have different colors and are displayed separately, like the moving image chapters B2 and B5 and the still images B3 and B4. Thus, since the icon C3 of the still image B3 being selected is shown on the time bar, it is easy to grasp the time axis.

  Reference is again made to FIG. In the list display state of the moving image and still image display Ba and the chapter display Bb, the moving image file itself and the still image captured during moving image shooting can be selected by the JOG dial or the like. First, during a moving image and still image selection display (display 605), when a normal reproduction operation or the like is performed with the moving image A selected, the moving image A is reproduced to the full screen.

  Next, when the cursor is moved from the moving image to the moving image chapter and still image list state (displays 606 and 607), the moving image chapter and the still image during moving image shooting can be selected. When the target moving image chapter or still image is selected from the still image list and the still image is played back, the corresponding still image is displayed on the entire screen (display 608). When the CPU 111 operates as an image reproduction control unit and a moving image chapter is selected, a moving image corresponding to the moving image chapter may be reproduced and displayed on the LCD 110 in a paused state.

  Similarly, when moving image reproduction is performed, when the CPU 111 operates as an image reproduction control unit and a moving image chapter is selected, the moving image is reproduced and displayed on the LCD 111 from the timing of the moving image chapter, and a still image is selected. In this case, a moving image is reproduced and displayed on the LCD 111 from this still image capturing timing. Specifically, the CPU 111 causes the LCD 111 to reproduce and display a moving image corresponding to the generation timing of the moving image still image data corresponding to the selected still image (display 609).

  In the case of a still image that is not a still image shot during moving image shooting, a thumbnail list is displayed with the Wide key (display 604). Further, even when the Wide key is pressed from the list display (displays 605, 606, 607) of the moving image and still image display Ba and the chapter display Bb, the thumbnail display is similarly displayed (display 604). When a still image shot during moving image shooting is selected in the thumbnail list display, when a moving image file that has been shot still image is selected and the Tele key is pressed, the above moving image and still image display Ba and chapter are displayed. The display shifts to a list display with the display Bb (displays 605, 606, 607).

  FIG. 12 is a diagram showing transition of a display screen by an LCD in a conventional camera device. As shown in FIG. 12, in the playback mode of the conventional camera device, only the moving image and the still image captured during the moving image shooting are displayed in order. In the thumbnail list display, the moving image and the still image taken during the moving image shooting are simply arranged in time series. For this reason, it has been impossible to read information such as which file is a still image during moving image shooting and at what timing the still image is shot.

  However, according to the camera device 1 of the present embodiment, when a still image is shot during moving image shooting, the CPU 111 operates as shooting management information writing means, and the above shooting management information is converted into a moving image file and a moving image. Each file is written to a still image file including medium still image data. Further, the CPU 111 operates as a display control unit, and based on the shooting management information, the moving image corresponding to the moving image data and the still image corresponding to the moving image still image data can be distinguished from each other, and in time-series order together with the moving image. It is displayed on the LCD 110. Therefore, it is possible to visually grasp which still image was shot at which moment and which still image was shot during movie shooting, and management is easy even if a large number of still images are shot during movie shooting. Thus, the convenience of the user can be greatly improved.

  In addition, according to the camera device 1 of the present embodiment, when the moving image data is divided into a plurality of moving image chapters, the CPU 111 operates as a display control unit to specify still image data in the moving image. Since the display Ba and the chapter display Bb for specifying each moving image chapter are combined and displayed on the LCD 110 in time series order (see FIG. 6), it is possible to make it easier to grasp the shooting timing of the still image with respect to the moving image.

  In addition, according to the camera device 1 of the present embodiment, the CPU 111 operates as a display control unit, and the generation timing of the still image data in the moving image during the generation time of the moving image data can be specified based on the shooting management information. Since the time bar C as the specific display is displayed on the LCD 110, it is easy to grasp the time axis, and it is possible to easily grasp at a glance at which timing each still image was taken.

  Further, in the camera device 1 of the present embodiment, the CPU 111 operates as an image reproduction control unit, and when one of the moving image chapters is selected based on the chapter display displayed on the LCD 110, the moving image chapter is responded. Play the video in a paused state. Further, when the CPU 111 operates as image reproduction control means and any one of the still images in the moving image is selected based on the still image display Ba displayed on the LCD 110, the generation timing of the still image data in the moving image is set. Play the corresponding video. Thereby, according to the camera device 1 of the present embodiment, user convenience can be improved.

  The present invention is not limited to the above-described embodiment, and various modifications can be made.

(Modification 1)
In the present embodiment, the CPU 111 (shooting management information writing unit) displays the moving image display A in a reduced size, and the right side of the moving image display A is a still image display Ba by still images B3 and B4 taken at the time of moving image shooting. The displayed video is combined with the chapter display Bb of the video chapters B2 and B5, and the time bar C is displayed below the video display A. The video display A, the video chapters B2 and B5, and the still image B3 are displayed. , B4, and time bar C are not limited to this embodiment. FIG. 8 is a diagram showing a display screen of still image display and chapter display on the LCD in the camera device according to the first modification. For example, as shown in FIG. 8, the CPU 111 (shooting management information writing unit) does not display the moving image display A in a reduced size but overlays the moving image display A with the still image display Bb by the still images B3 and B4. The time bar C may be displayed together with the chapter display Bb by the moving image chapters B2 and B5 and arranged in time series. Also in the first modification, the same advantages as in the present embodiment can be obtained.

(Modification 2)
9 and 10 are diagrams showing display screens of still image display and chapter display on the LCD in the camera device according to the second modification. As shown in FIG. 9 and FIG. 10, in the second modification, the CPU 111 (shooting management information writing means) displays the still picture display Ba by the still pictures B3 and B4 and the conventional chapter list display Bb by the moving picture chapter B2. They are combined and arranged on the LCD 110 in chronological order. Further, the CPU 111 (shooting management information writing means) causes the LCD 110 to display moving image file related information related to the corresponding moving image file corresponding to the shooting management information written in the still image file instead of the moving image A. In the second modification, as the moving image file-related information, the still image shooting time E for the moving image is displayed below the display portion of the still image display and the chapter display. The moving image file related information may be a moving image file name, a moving image unique number, or the like. Also in the second modification, the same advantages as in the present embodiment can be obtained.

  FIG. 11 is a diagram illustrating transition of a display screen by the LCD in the camera device according to the second modification. In FIG. 11, the screen display 1101 of FIG. 9 is displayed instead of the screen display 606 in FIG. 6, and the screen display 1102 of FIG. 10 is displayed instead of the screen display 607. Other screen displays are the same.

  In the conventional camera device, when the T key is pressed when a moving image is selected, a moving image chapter selection screen is displayed. However, as in Modification 2, this can be expanded to display a still image file selection in the same manner ( Display 1101, 1102). In the camera device of the second modification, when the OK key is pressed in the video chapter, the video playback starts from the corresponding location (display 609) as in the past (in the case of a still image, the video playback from the corresponding location (display 609) or One of the features is that it is possible to select either an enlarged display (display 608) of a still image. As a result, the still image shooting timing during moving image shooting can be used in the same manner as the moving image chapter, and the convenience for the user is greatly improved.

  What is important here is that moving image chapter information is not created at the timing of still image shooting. Of course, it is easy to implement a method that simply inserts a video chapter at the timing of still image shooting. However, when video data is copied to another device that can handle video chapters, chapters that are not intended by the user The data will be there. If it is basically desirable for the chapters to be entered by the user, the above method becomes undesirable.

  Therefore, by handling the still image shooting timing separately from the movie chapter, the still image list display function and movie playback position selection function during movie shooting can be used only on devices equipped with this function, and this function is not installed. This makes it possible to minimize the effects of using the same file on other devices.

  In addition, when it is possible to select a thumbnail image of a moving image with a user interface as shown in FIG. 11, the still image file position is specified by specifying the still image file position in the same manner as setting the chapter information position to the thumbnail. It is possible to designate an image at as a thumbnail image. Since the moment when a still image is shot is often the timing to be particularly noticed in a moving image file, this function is effective for thumbnail image designation.

  In the present embodiment, the shooting management information is written in the moving image file and the still image file and managed together with the moving image file and the still image file. However, the shooting management information is a management file different from the moving image file and the still image file. And may be managed separately from the moving image file and the still image file.
