Abstract
PURPOSE:To increase the speed of image processing by using simple hardware constitution to produce the address of a partial rectangular area in a memory. CONSTITUTION:An address (f) which defines a head address as an initial value and increases one by one is successively outputted via an address bus. When a strobe is equal to width L', the value (L-L') is added to the address (f). Then the address (f) obtained by adding addresses to the address obtained by said addition one by one is successively outputted via the address bus. When the strobe is equal again to the width L', the value (L-L') is added again to the address (f) at that time point. Hereafter, the same operation is repeated. In such a way, the address corresponding to an area A can be produced in a simple hardware constitution. Thus the image processing speed is increased.
