Abstract

Official abstract text for this publication.

An image processing apparatus configured to convert input image data into halftone image data by halftone-processing the input image data includes a prediction unit configured to predict a density of a pixel of interest, which is achieved when the halftone image data is printed, based on a group of halftone-processed pixels neighboring the pixel of interest according to a prediction method determined according to a halftone-processed pixel value of the pixel of interest, and a control unit configured to control the halftone processing according to the density predicted by the prediction unit.

First claim

Opening claim text (preview).

What is claimed is: 1. An image processing apparatus, for an image forming apparatus printing an image, the image processing apparatus being for converting input image data into halftone image data by halftone-processing the input image data, the image processing apparatus comprising: a prediction unit configured to predict a density of a pixel of interest, wherein the density is achieved when an image according to the halftone image data is printed, based on a group of halftone-p…
