摘要： In forming a multi-colored image by superimposing a plurality of plane images, positional offsets of the plane images are prevented, thereby obtaining high quality color images. The timing at which image data corresponding to each plane image is generated is controlled in accordance with the phase difference between the sub-scanning start signal indicating the rotational timing of an image carrier and the main-scanning start signal representing the rotational timing of a rotating polygonal mirror. Various controls are further performed.

摘要： 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.

摘要： The color determination circuit 308 detects hue of the color image information, and the controller 205 decides a color component to be separated (separation color) in accordance with the detected hue. Output color by the printer 204 is set in correspondence with the separation color. The two-color-separating circuit 303 separates the color image information into image information on at least two color components in accordance with the decided separation colors. The separated image information on the each color is transmitted to the printer 204 via printer density correction circuits 304 and 305, and a buffer 306. Thereby it is possible to provide an image processing apparatus capable of setting and changing the separation color and the output color by automatic operation or by simple manual operation, thus the expression of the image forming can be improved.

摘要： When an original image of a full color is reconstructed by two colors, it is intended to prevent that a part of the original image is not reconstructed. An image of a full color original is read by a CCD, thereby forming signals of R, G and B. In an image processing unit, the R, G, and B signals are converted into red and black signals. The red and black signals are sent to a printer unit and an image is formed in red and black.
