Abstract
When all frames, which are used for reference, are stored, vector retrieval meansfind correlation with a reference frame. Compression type determination meanscompare a predictive error of the found vector position and an average deviation within the frame, and select the compression type with high compression efficiency. Compression mode determination meansselect anyone of the compression process at the time of the high-speed mode and the compression process at the time of the normal mode based on the compression type. In the compression process at the time of the high-speed mode, for the macro block the difference between it and the predictive block is not taken in motion predictive meansit is converted into a frequency component in frequency conversion meansis quantized in quantization meansand is coded by the compression in variable-length coding meansto output the compression code from output means
