ABSTRACT:
A method and apparatus for displaying images is presented in which intra-frame encoding is performed on image data at N frame intervals, where the thinned-out frames are encoded by prediction from the preceding frame codes. The frame being decoded is identified when an instruction for temporarily stopping a moving image and displaying it as a still image is given by an operation panel. If the frame being decoded is not an interpolative frame, the decoded image data is displayed when the decoding operation is complete. If, on the other hand, the frame being decoded is an interpolative frame, the intra-frame encoded frame nearest to the frame being decoded, or a predictive frame, is displayed.
