Abstract

PROBLEM TO BE SOLVED: To attain improvement in the display of the state of a number of preservable images by performing control so as to display the number of images recordable in a recorder on a display device when the number of images recordable in the recorder gets less than the number of images which can be fetched into an image preserving device. SOLUTION: For example, the number of burst consecutive photographable frames is 12, the storage area of a buffer memory is empty and the number of frames writable into a memory is 12. In this case, a counter display part 103 is changed from turned-on display state to flickered display state. In the case the number of burst consecutive photographable frames is 8 to 12 and the number of frames writable into the memory is 8, the counter display part 103 is changed from turned-on display state to flickered display state. The number of burst consecutive photographable frames can be recognized simultaneously with the conditions of the number of remaining frames to be recorded on an attachable and detachable recording medium and missing of shutter chance can be avoided beforehand.

Description of the Related Art In a conventional image pickup apparatus such as an electronic stell camera, burst continuous shooting (images are temporarily stored in a buffer memory or the like, and time-consuming image processing and image compression are performed when time is required. Even those models that can increase the frame rate of continuous shooting by recording (storing) in the camera), those that do not display the number of burst frames or those that display information on only the number of burst frames on the external display are commercialized However, there is no display that clarifies the number of frames that can be shot and the number of frames in burst continuous shooting, or that displays the burst state together with other displays. Further, when the storage area of the buffer memory becomes full, there is no display that clearly indicates when it will be ready to take a picture next.

更に重要となるものである。As described above, according to the present embodiment, it becomes clear at some time that the photographing is ready, so that it is easy to adjust the photo opportunity and, at the same time, the state of the imaging device becomes clear. The usability of the device is significantly improved. In contrast to a silver halide camera using a roll film that can shoot the next frame just by feeding the film and charging the shutter, the electronic still camera is in a shooting standby state by image processing, image compression, transfer, etc. However, unlike a silver halide camera, which has a sound to indicate that a mechanical operation has ended, there is no idea when the processing will end.
This is even more so if the number of pixels is high.
Therefore, the technology according to the present embodiment as described above will become even more important in the future.
