ABSTRACT:
An image forming apparatus discriminates a color of an inputted color image for each pixel and generates a first color component and a second color component. The apparatus compares values of the first and the second color components, and selects and outputs the color component having a larger value. Meanwhile a color component which is not selected is diffused to neighboring pixels. When pixels neighboring a pixel of interest in a predetermined area are filled with one color component, the other color component is selected and outputted regardless of the values of the first and second color components.
