Abstract:
1. An image processing apparatus that processes image data to form an image by an image forming unit, the image processing apparatus comprising: a generation unit configured to generate correction information to offset displacement of an image formed by the image forming unit in a sub-scanning direction; a determination unit configured to determine an application area in the main-scanning direction of the correction information based on a main-scanning width of the image forming unit; a first correction unit configured to perform correction by line shifting of the image data in the sub-scanning direction at a position in a main-scanning direction based on the correction information defined by the application area; a second correction unit configured to perform correction of pixel values of the image data based on the correction information defined by the application area to smooth line shifting step height generated by the correction performed by the first correction unit based on the correction information defined by the application area; and a transmission unit configured to transmit to the image forming unit the image data corrected by the first and second correction unit.
