ABSTRACT:
Attribute information accessory to a pixel can be used to determine whether to execute an interpolation process of less than one pixel at a scan line changing point in color misregistration compensation for a printout from an image forming apparatus having a characteristic shifted in the laser scanning direction for each color. When the attribute information is an attribute representing execution of the interpolation process of less than one pixel, it is enlarged in the sub-scanning direction. Attribute information of each color component can be generated from attribute information accessory to a pixel by using the attribute information accessory to the pixel, and each color component value which forms the pixel.
