Abstract
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.
