<p>PROBLEM TO BE SOLVED: To prevent the influence of skipping from being given to another frame in the case one frame reproduction is skipped and to enable a moving picture reproduction processing to be executed, which is adapted to the throughput of a microcomputer, while suppressing the deterioration of image quality in moving picture reproduction by skipping the reproduction of the B-picture of the frame when a reproduction image is monitored and the delay of the processing is judged. SOLUTION: A decoding circuit 41 fetches the bit stream of the moving picture which is compressed by an MPEG: 1 and the decoding image of the MPEG image is reproduced and outputted by a decoding algorithm. A display controller 42 controls the operation of a display buffer 43 for fetching the decoding image from the decoding circuit 41 and also permits a skip signal 42a to be active in the case the fetching of the decoding image seems to be delayed after monitoring an operation state. Skip judging equipment 40 judges the frame to be skipped by a prescribed algorithm while the skip signal 42a is active and outputs the judgement result signal 40a to the decoding circuit 41.</p> |
