A digital camera 10 includes a CCD imager 14. When an interval photographing or an animation photographing is selected, an object is photographed by the CCD imager 14 for a plurality of times, and compressed image data is generated each photographing by each photographing. The generated compressed image data is stored in a temporary area of an magnetooptical disk 42. Upon completion of photographing the desired number of frames, the generated respective compressed image data are converted into a moving image file, and moved to a proper recording area of the magnetooptical disk 42. Frame rate information is written in the moving image file. Upon reproducing, firstly, the frame rate information is detected, the compressed image data of each frame is reproduced in accordance with this information. The moving image that moves at a desired speed is displayed on a monitor 30.
