Abstract
This invention can perform inkjet printing operation which can reduce density irregularity and reduce deterioration in image quality without causing any deterioration in graininess. The invention relates to an image correction method or inkjet printing apparatus which divides the scanning area of a printhead into a plurality of count areas and printing areas in the scanning direction, counts the number of dots printed in each count area, and forms an image by modifying image data in the next printing area in accordance with the counted number of dots. Image data is modified by counting multilevel image data. The modified multilevel image data is converted into binary data. The binary data is then printed.
