Patent ID: 8305634

Claim:
An image processing device, comprising: a memory that stores conversion characteristic information corresponding to respective recording portions of an image recording device that records an image at a recording medium while moving a recording unit, which is provided with a plurality of the recording portions arrayed in a first direction, relative to the recording medium in a second direction that is perpendicular to the first direction, the conversion characteristic information expressing conversion characteristics for converting image data in units of one pixel; a first processing unit that performs a conversion processing procedure along the first direction, continuously converting respective sets of pixel data, each of the sets of pixel data being for recording a plurality of pixels aligned in the second direction and to be recorded by a different one of the recording portions, using conversion characteristic information stored in the memory corresponding to the respective recording portions; a second processing unit that performs an image processing procedure in units of a plurality of pixels of the image data that has been processed at the first processing unit, the image data being aligned in the order of processing at the first processing unit; and an output unit that outputs the image data that has been processed at the second processing unit to the image recording device as aligned in the first direction.
