Patent ID: 7619775

Claim:
An image processing system comprising: a host computer; an image processing apparatus; and a transferring unit that transfers image characteristics information and pixel data of an image from the host computer to the image processing apparatus; wherein the host computer includes: an image-characteristics-information generating unit that generates the image characteristics information of the image; and wherein the image processing apparatus includes: an amount-of-color-shift storing unit that stores information concerning an amount of color shift in a sub scanning direction at an exposure position for scanning of an image carrier in a main scanning direction; an image data storing unit that stores multiple pieces of the pixel data; a coordinate conversion unit that converts the coordinate of a writing address used in the writing in the image data storing unit, based on an amount of color shift in integer pixel units, and reads out the pixel data concerning a target pixel from the image data storing unit in accordance with address information after the coordinate conversion; and a density conversion unit that converts the pixel density of the pixel data based on the image characteristics information and the amount of color shift in fractional pixel units.
