IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

摘要

A moving image processing apparatus includes a storage unit to store encoding parameter information generated by encoding each of multiple blocks obtained by partitioning an image; a candidate list generation unit to generate a prediction vector candidate list including two prediction vector candidates for a motion vector of each of the blocks to be processed; a difference vector calculation unit to set one bit of predetermined information in selection information for the prediction vector candidates if inter-prediction is applied to the block to be processed, and to calculate a difference vector representing a difference between the motion vector of the block to be processed and one of the prediction vector candidates designated by the selection information; and a variable-length encoding unit to apply variable-length encoding to the encoding parameter information including the difference vector and the selection information.
