<p>A digital still camera comprising a CPU 40 for compressing the one frame image data of a photo-shot having a constant data quantity by JPEG method into a variable length with the maximum data quantity of no more than 30k bytes, and a flash memory 41 for storing the compressed image data in an image region 412. The CPU 40 counts a number of frames of the image data already written onto the image region 412 and the unused data capacity, obtains a remaining number of frames allowable to be photo-shot from the number of frames of the image data already written onto the image region 412, and obtains a remaining number of frames allowable to be photo-shot from the unused data capacity of the image region 412, and also displays either smaller one as the number of frames allowable to be photo-shot. In case of compressing the data of the photo-shot images by JPEG method and storing the data onto a data recording medium in the digital still camera, it becomes possible to calculate accurately the remaining number of frames allowable to be photo-shot. <IMAGE></p> |
