Abstract
A corrector performs designating a target pixel belonging to a pixel array corresponding to an ejection port, the target pixel being designated sequentially as one of pixels arranged in an array direction, the pixel array being formed with the pixels in the N-value image data corresponding to dots formed by the ejection port respectively, allocating a corresponding one of N representative tone values out of L tone values of L tones to a tone value of the target pixel of the N-value image data, adding the correction value to a representative tone value of the target pixel, thereby obtaining a corrected tone value of the target pixel, quantizing the corrected tone value of the target pixel to N tones; and diffusing an error generated in quantizing the corrected tone value to the corrected tone value of an adjacent pixel adjacent to the target pixel in the array direction.
