Image data processing device and image reading apparatus

摘要

An image data processing device includes a first integrated circuit, a second integrated circuit, and a third integrated circuit. The first integrated circuit includes a first image processing circuit for first image processing for image data in a first memory, and a first serial interface for direct memory access transfer between the first memory and a third memory. The second integrated circuit includes a second image processing circuit for second image processing for image data in a second memory, and a second serial interface for direct memory access transfer between the second memory and the third memory. The third integrated circuit includes a third image processing circuit for third image processing for image data in the third memory, and a third serial interface for direct memory access transfer between the third memory and the first memory, and between the third memory and the second memory.
