REFRESHING CONTROL CIRCUIT

摘要

PURPOSE:To realize a refreshing control circuit in circuit construction capable of easy LSI. CONSTITUTION:Predicted image data and '0' block data are selectively selected and outputted by a selector part 11, and the selector part 11 receives the number of counted blocks from a single screen block counter part 13 with its decoder part 12 and each time the received counted number coincides with a decoded value, outputs '0' block data. Then a shifting control counter part 14 gives the counter part 13 a load value which controls the single screen block counter 13 to shift the number of counted blocks by one each time one screen is updated.
