Abstract:
1. An image processing device: with a processing unit that processes image data in units of one scan line, and a memory unit that can read and write image data in units of one scan line, characterized by the fact that it comprises at least one input line memory that can store image data for one scan line and is able to write input image data at the transfer speed of the input image data and read the written image data at a faster speed than the transfer speed of the input image data, a transfer unit that inputs at least the image data read from the aforementioned input line memory to the aforementioned processing unit memory unit, a selector that selects the image data output from the aforementioned processing unit or memory unit, and at least one output line memory that can store image data for one scan line and is able to write the image data selected by the aforementioned selector at a speed faster than the transfer speed of the image data and read the image data in units of one scan line at a prescribed speed; wherein the aforementioned processing unit and memory unit receive image data for one scan line at a faster speed than the transfer speed of the input image data, perform prescribed processing tasks, and then output the processing results at a faster speed than the transfer speed of the input image data.
