Image processing apparatus and image processing method

摘要

A correction in less than one pixel raises an issue of generation of image defect such as density unevenness caused by a destruction of a screen pattern that generates a cycle of image data. To solve this issue, an image processing apparatus includes a correction unit configured to perform a correction less than one pixel on image data, and a changing processing unit configured to perform a correction by one pixel on image data, wherein the correction unit performs processing for correction in less than one pixel by shifting a pixel according to a moving locus synchronized with a cycle of the image data.

主权项

1. A printing apparatus, comprising:
a halftoning unit configured to halftone image data using a screen which has a cycle of patterns to obtain halftoned image data; a determination unit configured to determine a moving locus which is synchronized with the cycle of patterns of the screen and connects the patterns of the screen with each other; and a correction unit configured to digitally correct, on a basis of a position deviation and the determined moving locus, the halftoned image data.
