Abstract

To perform a motion picture format conversion at high speed in a motion picture converting apparatus, the apparatus comprises: input device 101 for inputting a digital image signal constituted of blocks, each block being orthogonally transformed; a frame memory 102 for storing the digital image signal; block reading device 103 for reading the blocks or a macro block from the frame memory in response to a request; region dividing section controlling device 109 for sending a read request to the block reading device; component extracting device 104 for extracting a low-frequency component alone of the captured image signal; two low-resolution frame memories 105 for storing extracted information; motion detecting device 106 for detecting a motion in accordance with the information in the low-resolution frame memories; a region dividing section 113 including macro block classifying device 107 for labeling the macro block in response to a motion detection result by the motion detecting device and label storing device 114 for storing a label of the macro block;
decoding device 110; an encoding section 111 for changing an encoding of the macro block in response to the label in the label storing device; and output device 112 for outputting the coded signal.
