Abstract
The image processor comprises a switch that divides image data into m×n pixels, having n lines with m pixels per one line; a group of line memories that store the divided image; a compression device which batch compresses the image data of m×n pixels. Further, a command control unit provides control so as to send the (n−1) lines of image data among m×n pixels of image data to the group of line memories, and the remaining one line of image data directly to the compression device 902, and to send the m×(n−1) pixels of image data stored in the line memories to the compression device.
