IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD
First Claim
1. An image processing apparatus configured to generate recording data used in an image forming processing for carrying out an image formation by performing a recording scan by plural times on a same image region on a recording medium, the image processing apparatus comprising:
- a division unit configured to divide input image data into image data for each of the recording scans;
a quantization unit configured to quantize, based on the divided image data for each of the recording scans, the image data for each of the recording scans; and
a generation unit configured to generate, based on the quantized image data for each of the recording scans, recording data for each of the recording scans,wherein the division unit divides the input image data into the image data for each of the recording scans based on a division rate periodically varying in accordance with a spatial position of an image represented by the input image data.

Abstract
An image processing apparatus configured to generate recording data used in an image forming processing for carrying out an image formation by performing a recording scan by plural times on a same image region on a recording medium, includes a division unit for dividing input image data into image data for each recording scan, a quantization unit for quantizing, based on the divided image data for each recording scan, the image data for each recording scan, and a generation unit for generating, based on the quantized image data for each recording scan, recording data for each recording scan, in which the division unit divides the input image data into the image data for each recording scan based on a division rate periodically varying in accordance with a spatial position of an image represented by the input image data.
