Abstract
A SCENE CHANGE DETECTION DEVICE CAPABLE OF DETECTING A SCENE CHANGE RAPIDLY FROM A STREAM CODED USING SUCH A CODING SCHEME THAT CARRIES OUT PREDICTION CODING USING DECODED PIXELS. AN ENTROPY DECODING SECTION 31 PERFORMS ENTROPY DECODING OF PREDICTION MODES FROM THE CODED STREAM. AN INTRA-PREDICTION MODE HISTOGRAM DIFFERENCE GENERATING SECTION 32 ACQUIRES THE PREDICTION MODES PASSING THROUGH THE ENTROPY DECODING BY THE AMOUNT CORRESPONDING TO MULTIPLE BLOCKS WITHIN A SINGLE PICTURE TO GENERATE A HISTOGRAM, AND COMPARES THE HISTOGRAMS OF THE PREDICTION MODES GENERATED FOR INDIVIDUAL PICTURES TO CALCULATE THE DEGREE OF SIMILARITY BETWEEN THE HISTOGRAMS. A SCENE CHANGE DECIDING SECTION 33 DECIDES AS TO WHETHER A SCENE CHANGE OCCURS BETWEEN THE PICTURES FROM THE DEGREE OF SIMILARITY OBTAINED BY THE INTRA-PREDICTION MODE HISTOGRAM DIFFERENCE GENERATING SECTION 32.
