摘要:
A first delay memory is input with an input image frame output from a ME (motion estimation) processor, and delays output to a first adder for carrying out a prediction residual generation process a predetermined time period. A second delay memory is input with an inter-prediction luminance image frame, and delays output to a prediction selection circuit a predetermined time period. A third delay memory is input with motion vector information output from the ME processor, and delays output of the motion vector information to an inter-prediction chrominance image creation processor a predetermined time period.
