Reference numeral 4 denotes an I / F for outputting video to an external display device. Reference numeral 8 denotes an aspect ratio information reading control unit. Reference numeral 9 denotes an operation switch. A system control device 5 includes a CPU and the like.

  An imaging operation of the imaging apparatus 100 will be described. The system controller 5 detects a change in the state of the operation switch 9 (configured by the camera main SW, release SW, operation buttons, etc.) by the photographer, and starts supplying power to the other circuit blocks. Then, the system control device 5 determines the shutter speed, the aperture value, and the like by the imaging optical system 11 and the control device 15 at regular intervals, and the conditions for capturing the image and the image to be captured are displayed on the monitor display unit 3. Display in live view.

  When the photographer instructs the photographing operation by operating the operation switch 9, the imaging optical system 11 is activated by a control signal from the system control device 5, and an optical image by the imaging optical system 11 is formed on the imaging element 12. The electrical image signal output from the image sensor 12 is converted into a digital signal by the A / D conversion circuit 13 in pixel order, and then input to the image processing circuit 14. The image processing circuit 14 generates image data of each color component of R (red), G (green), and B (blue) based on an image signal captured by the image sensor 12. Each color component data is temporarily stored in the frame memory 6. The memory control device 1 compresses the image data of each color in the frame memory 6 based on a predetermined compression format, and records the compressed data in the external memory 7. The external memory 7 is a non-volatile memory such as a flash memory, for example.

  The photographer can specify an aspect ratio for image data (recorded image data) recorded in the external memory 7 by the aspect ratio setting unit 10. The aspect ratio information (set aspect ratio information) set by the aspect ratio setting unit 10 is added to the image data recorded in the external memory 7. In order to select the aspect ratio to be added, the menu screen shown in FIG. 2 is displayed on the monitor display unit 3, and the photographer selects the aspect ratio to be set with the operation switch 9. The aspect ratio that can be added is any one of 3: 2, 4: 3, 16: 9, and 1: 1.

  When the aspect ratio is set, a line corresponding to the set aspect ratio is displayed on the monitor display unit 3 as shown in FIG. FIG. 3A shows a display example when the aspect ratio is set to 3: 2. FIG. 3B shows a display example when the aspect ratio is set to 4: 3. FIG. 3C shows a display example when the aspect ratio is set to 16: 9. FIG. 3D shows a display example of the monitor display unit 3 when the aspect ratio is set to 1: 1.

Similarly, when the aspect ratio information is not added, the line corresponding to the aspect ratio is not displayed, and the display on the monitor display unit 3 is as shown in FIG.

  As shown in FIG. 4, the file structure of the recording image data includes an image data portion and a header portion. In the image data portion, RAW image data, JPEG image data for display, and DCF thumbnail image data are recorded. In the header portion, size information of RAW image data, aspect ratio information, other shooting information, and the like are recorded. The aspect ratio of the RAW image data and the display JPEG image data is the aspect ratio of the image sensor 12. The aspect ratio of the DCF thumbnail is 4: 3 defined by the standard. However, an image maintaining the aspect ratio of the image sensor 12 is reduced and recorded in the DCF thumbnail image data. FIG. 4A shows a schematic diagram of the file structure of a file to which an aspect ratio of 3: 2 is added. FIG. 4B shows a schematic diagram of the file structure of a file to which an aspect ratio of 4: 3 is added. By recording a numerical value corresponding to the set aspect ratio as aspect ratio information, the aspect ratio at the time of shooting can be identified.

  The recorded image data recorded in the external memory 7 is reproduced and displayed when the user performs a predetermined operation with the operation switch 9. That is, in accordance with the operation, the compressed data of the reproduction designated image recorded in the external memory 7 is read out to the memory control device 1 and decompressed. The image data restored by decompression is written in the image display memory 2 and displayed as an image on the monitor display unit 3.

  The modes for displaying recorded images are mainly used for confirmation, and there are a normal playback mode for individually reproducing designated images and a slide show mode for mainly viewing. In the normal playback mode, the image displayed in response to an instruction from the user operation switch 9 is manually switched. On the other hand, the slide show mode is a mode in which a plurality of images are reproduced in an automatic switching manner, and the images recorded in the external memory 7 are automatically switched after being displayed for a specified time.

  FIG. 5 shows an example in which an image with aspect ratio information added is displayed on the monitor display unit 3. FIG. 5A shows a display example when the aspect ratio of the recorded image data matches the aspect ratio indicated by the set aspect ratio information added to the recorded image data.
