Filed: 1988-09-27
Abstract: PURPOSE:To prevent saturation gap from being generated by deciding a quantity of ink to be added corresponding to saturation detected based on the color material signal of each color obtained by converting chrominance signals of three colors and the chrominance signals of three colors. CONSTITUTION:The quantity of ink to be added is decided based on the color material signals C, M, and Y obtained by converting the chrominance signals R, G, and B of three colors from an input device 5 and signals amax, amid, and amin corresponding to the saturation of an original obtained by converting the color materials signals C, M, and Y by calculation of, for example, an approximate equation. At this time, the quantity of ink to be added is changed corresponding to not only the color material signals C, M, and Y, but the saturation. Therefore, it is possible to find the quantity of ink to be added successively to perform the optimum color reproducibility even when an image is changed extending over a high chromatic area to an achromatic area successively. In such a manner, smooth color reproducibility can be obtained without generating the saturation gap.

Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To attain automatic color selection with high accuracy by avoiding a chromatic color picture element from being a chromatic color when achromatic picture elements surrounding a chromatic picture element have a density change. SOLUTION: An image sensor 410 of an image scanner 400 reads R, G, B color components of an original image and provides an output of the result as 8-bit color image information. An image visualized by M, C, Y and BK toner on a photoreceptor drum 1 in a laser printer 100 is transferred onto transfer paper. An image processing unit applies various processing to an output image signal from the image scanner 400 and gives the result to the laser printer 100. When a maximum value of differences between R, G, B data for each picture element is extracted and larger than a prescribed value, the picture element is discriminated to be a chromatic color. Then a chromatic color picture element surrounded by achromatic colors is detected by pattern matching in the unit of 5. 5 picture element block.  When there exists any density change in the surrounding achromatic color area, the noted picture element is not selected for a chromatic color discrimination object.
