<P>PROBLEM TO BE SOLVED: To efficiently set an image processing parameter in DMA transfer using descriptor information. <P>SOLUTION: An image forming apparatus includes: a parameter difference management means for managing a difference between an image processing parameter which is already set or is not set in a batch transfer image processing parameter storage means and an image processing parameter necessary for image processing of a source image; an image processing parameter setting means for selecting an image processing pattern based on the management information of the parameter difference management means and setting an image processing parameter in a source image processing parameter storage means; a batch transfer image processing parameter writing means for writing the image processing parameter stored in the source image processing parameter storage means in the batch transfer image processing parameter storage means; and a DMA transfer means for performing DMA transfer to an image processing part based on descriptor information. <P>COPYRIGHT: (C)2010,JPO&INPIT |
