Abstract
Official abstract text for this publication.
An image forming apparatus that forms an image on a recording medium by performing recording (N) times (N is an integer of 3 or more) in a same region on the recording medium, the image forming apparatus includes a recording data generation unit configured to generate recoding data corresponding to each of the recording and a halftone processing unit configured to convert the recording data into halftone image data by a dither method using a matrix of a dot dispersion type, wherein the halftone processing unit generates the halftone image data of the (k)th time in such a manner that dispersibility of a dot pattern is improved in which each of the halftone image data corresponding to recording performed up to (k)th (2≦p≦N−1) time is accumulated in the same region.
First claim
Opening claim text (preview).
What is claimed is: 1. An image processing apparatus for generating halftone image data for forming an image on a recording medium by scanning a recording-element array including a plurality of recording elements and performing recording (N) times (N is an integer of 3 or more) in a same region on the recording medium, the recording-element array including a recording-element group for recording a first pass, a recording-element group for recording a second pass and a recording-ele…
