Claim:
1. A data transfer apparatus for transferring data to an image processor configured to perform a predetermined image process, using a buffer assigned to a storage device, the apparatus comprising: an input circuitry configured to perform a reading process to read data of an area, which is divided from image data, from the buffer storing the image data to be processed by the predetermined image process, and to perform a transmitting process to transmit the read data of the area to the image processor; and an output circuitry configured to perform a reception process to receive data generated in the predetermined image process from the image processor, to set a parameter for a writing process based on an area size obtained by using position information of a pixel, and to perform the writing process to write data generated from the received data to the buffer, the received data of the area including the position information, wherein the output circuitry comprises a first transfer circuitry configured to perform data transfer using direct memory access (DMA) between the output circuitry and the buffer, and wherein the output circuitry, in place of a CPU, is configured to set the parameter.
