B-frame processing apparatus with half pixel motion compensation for an image decoder.

摘要

A B-frame processing apparatus including a motion compensation apparatus in the unit of a half pixel for an image decoder adapted to a video appliance such as HDTV. According to the apparatus, motion compensation in the unit of a half pixel is performed in real time with respect to the image having been motion-compensated by frame memories, the half pixel motion-compensated image data is added by an adder to the image data provided from a restoring section, and then the added image data is provided to the frame memories for performing motion compensation in the unit of a pixel, while the order of the input image is adjusted corresponding to the display order of the final output image. <IMAGE>
