Abstract:
1. An image processing method comprising: performing, in parallel, a process of one of an image reading function, an image recording function, an image copying function and an image communicating function, while performing at least another process of the image reading function, the image recording function, the image copying function and the image communicating function; storing automatically a file of the image data processed by said performing independently of processes of the image reading function, the image recording function, the image copying function and the image communicating function; buffering the image data temporarily in a buffer before said storing, said buffer including a first buffer and a second buffer; causing a DMA transfer request when a storage capacity of at least one of said first and second buffers occupied by the image data reaches a predetermined preset value; and transferring the image data within said buffer by a DMA transfer over a DMA transfer line based on the DMA transfer request, wherein said transferring depends on a preset priority order when two DMA transfer requests for the image data in the first and second buffers are received simultaneously.
