ABSTRACT:
An image coding system determines an amount a data that is output by a coder of the system and also determines a target code produced amount based on the motion of an input image. The coder of the coding system encodes the input image. A record of a data amount of past coded data is used as the inference of the target code amount. Hence, proper coding can be performed in a sending side. Further, by converting the data amount into a value with a condition to be standard, accuracy of the inference may be improved. In addition, an indication of the power amount of the data to be coded is used as a factor for determining a target code produced amount to expedite a combination of a plurality of coding modes.
