【発明の名称】動画像信号の高能率符号化方式
Document Type and Number:
Japanese Patent JP2506332
Kind Code:
B2
Abstract:
A motion compensation difference interframe or inter-frame coding system having a block data redundancy compression and coding unit (30a), a PIXEL data coding unit (40) and a prediction data generating unit (20). The block data redundancy compression and coding unit (30a) codes a motion compensated (MC) difference between an input image in a form of a block and a motion predicted image from the prediction data generator unit (20), and transmits a coded data to a receiver. The PIXEL data coding unit (40) receives an error between the MC difference and a decoded MC difference from the block data redundancy compression and coding unit (30a), rearranges the error in the PIXEL data and codes the PIXEL error, when the error is greater than a predetermined value. The PIXEL coded data is also transmitted to the receiver. The prediction data generator unit (20) generates a predicted block data of the motion of the image.The redundancy compression and coding unit (30a) may include a filter circuit (9) rejecting pulse components contained in the MC difference.
