PURPOSE:To increase the speed of access to a closed area in the two-dimensional space in an image memory from an image processing control part. CONSTITUTION:An address outputted from the image processing control circuit 1 or an address calculated by an adder 5 is supplied from a selector 6 to an image memory 8, and the address supplied to the image memory 8 is held by a flip-flop 7 and supplied to the adder 5 to perform address arithmetic. At this time, the quantity of a space outside the closed area which is required is held in a flip-flop 2, the quantity of the space of the closed area to be accessed is held by a counter 3, and successive addresses of the closed area to be accessed are calculated and generated by the adder 5. |
