Abstract
An image processing apparatus includes: a first memory for storing 2-D image data wherein pixels are arranged in a matrix in the main scanning direction and sub-scanning direction orthogonal to each other; a second memory; and a data control section for controlling the first memory and second memory, wherein at least one of the first and second memories is constituted by a SDRAM. The data control section reads the image data from the first memory in blocks of m pixels in the main scanning direction and n pixels in the sub-scanning direction (where n and m are natural numbers), writes the read data into the second memory, and transmits data to the memory composed of the SDRAM by burst transmission and continuous supply of desired column addresses, thereby allowing the read image data to be rotated.
