ABSTRACT:
In order to reduce the power consumed by the circuit when the image data is transferred to a memory in a display means, a write region detecting means8is provided to detect the address region in the graphics memory2accessed for writing by the image data writing means1,and only such data that is within the region including the addresses accessed by the writing means1is transferred to the memory5in the display means4.The region including the accessed addresses may for example a rectangular region of from the minimum vertical direction address to the maximum vertical direction address Y among the accessed addresses, and from the minimum horizontal direction address to the maximum horizontal direction address among the accessed addresses.
