Abstract
By setting a parameter in accordance with features of a unique portion appearing in a print image, the unique portion in the print image is efficiently determined. The image is printed on a sheet along with a relative movement in a main scanning direction of the sheet and a print head on which multiple printing elements are arrayed in a sub-scanning direction. One division area is set such that a size in the main scanning direction is greater than a size in the sub-scanning direction. A shift amount from one division area to another division area is set such that a shift amount in the main scanning direction greater than a shift amount in the sub-scanning direction.
