摘要:
An amount of data coded in the past is detected at a prescribed period. Criteria for deciding whether a pixel block of interest is to be coded by processing for motion-compensated coding of interframe difference, processing for coding of interframe difference without motion compensation or processing for intraframe coding are adjusted based upon the amount of code detected.
