Patent ID: 8049927

Claim:
An image processing apparatus comprising: an image forming unit configured to form an image on a photosensitive drum by scanning the photosensitive drum with a light corresponding to image data; a storage unit configured to store image data of at least a plurality of lines; a data reading unit configured to read out image data in a line direction of the scanning line from said storage unit on the basis of a read start address of the image data and a burst transfer length, and to burst-transfer the image data; a setting unit configured to set a switching address in the line direction for switching a line of image data read out by said data reading unit, the switching address being set so as to correct a curvature of the scanning line; a generation unit configured to generate, based on the switching address, a second read start address for reading out image data of a second line, so as to read out image data of at least a first line before line switching and the second line after the line switching, by burst transfer, in accordance with the switching address set by said setting unit; and an output unit configured to output image data for generating image data of one line on the basis of image data corresponding to an effective area in the image data which is read out from said storage unit and burst-transferred by said data reading unit.
