Image processing apparatus, image forming apparatus, image processing method, and program product thereof

Abstract

It is objected to provide an image processing apparatus achieving decrease of memory volume to be used, simplified print process, and enhancement of productivity. Firstly, a plurality of image data are recorded in memories provided for respective colors. Based on the image data or mode selection by a user, it is determined that whether a multi-color image or a monochrome image is to be outputted. Next, memoriesof respective colors transmit image data of respective colors to a computing unitin accordance with readout-timing signals from a timing selector. In case a multi-color image is to be outputted, the timing selectortransmits readout-timing signals of respective colors taking time difference length of which is predetermined for each color. In case a monochrome image is to be outputted, the timing selectortransmits readout-timing signals of respective color simultaneously. A computing unitforms monochrome image data in accordance with image data of respective colors, whereby process of monochrome print is simplified.
