Patent ID: 8514455

Claim:
An image processing apparatus for forming an image by performing relative-reciprocating-scanning by moving, on a same area on a recording medium, a recording unit including recording elements corresponding to a plurality of density components, the image processing apparatus comprising: a setting unit configured to set, for each of first image data and second image data, scanning data of each scanning based on each of the first image data and the second image data, the first image data corresponding to a first density component and the second image data corresponding to a second density component different from the first density component; and a halftone processing unit configured to perform halftone processing on scanning data of each scanning corresponding to the first density component and scanning data of each scanning corresponding to the second density component, and generate halftone image data indicating a dot pattern for each scanning corresponding to the first density component and halftone image data indicating a dot pattern for scanning corresponding to the second density component, wherein a dot pattern of the m th scanning corresponding to the first density component among a plurality of dot patterns corresponding to the first density component is generated such that a dot relationship between dots of the dot pattern of the m th scanning corresponding to the first density component and dots of a dot pattern of the m th scanning corresponding to the second density component is more exclusive than a dot relationship between dots of the dot pattern of the m th scanning corresponding to the first density component and dots of a dot pattern of the n th (n≠m) scanning corresponding to the second density component.
