Patent ID: 7719713

Claim:
An image processing apparatus, comprising: a conversion unit that, by using a binarization processing for expressing a gray level by a dot density, converts input image information which includes a first color component and a second color component and in which, with regard to each of the color components, the number of gray levels per pixel is no less than three, into output image information in which a gray level of the input image information is expressed by a dot density with regard to each of the color components and in which, for each of the color components, the number of gray levels per pixel is two; and an output unit that outputs the output image information obtained by the conversion unit; wherein in at least a part of gray level regions, when gray level values of the input image information are identical for the first color component and the second color component, the conversion unit converts the input image information into the output image information such that dot sizes in the output image information become different between the first color component and the second color component.
