Abstract:
A motion picture converting apparatus comprising:input means for inputting a digital image signal constituted of a macro block which is an aggregation of blocks, each block being orthogonally transformed;a frame memory for storing said digital image signal;block reading means for reading said blocks or said macro block from said frame memory in response to a request;region dividing section controlling means for sending a read request to said block reading means;component extracting means for extracting a direct-current component alone of a captured image;two low-resolution frame memories for storing extracted information;motion detecting means for detecting a motion using the information in said low-resolution frame memories;a region dividing section including:macro block classifying means for labeling said macro block in response to a motion detection result by said motion detecting means, andlabel storing means for storing a label of said macro block;decoding means;an encoding section for changing an encoding of said macro block in response to the label in said label storing means to produce a coded signal; andoutput means for outputting the coded signal.
