Abstract
To provide an image processing technique compatible with both a CCD and a CIS, which controls storage of image data read by each device in a memory and the read of the stored data for each rectangular area to obtain a high memory efficiency, an image processing apparatus includes an input section which executes input processing of image data read by an image reading device in accordance with the data output format of the device, an output data control section which distributes the image data that has undergone the input processing by the input section in accordance with the output format of the image reading device, an address generation section which generates address information corresponding to the output format to store the distributed image data in a memory, and a memory control section which DMA-transfers the distributed image data to the memory and stores the image data on the basis of the generated address information.
