摘要： An image processor receives color image data and converts them to image data of cyan, magenta, yellow and black necessary for image forming. The received color image data are subjected to color aberration correction, and various image data processing is performed on the image data after the color aberration correction in order to improve the precision of image processing on a color document image. The image data processing includes, for example, a specified color document is decided, automatic color selection and magnification change.

摘要： The inventive image processing apparatus takes steps of 1) dividing an image to be processed into numerals of blocks; 2) determining whether a block is a color block or not; 3) determining whether the image is a color image or not based on the rate of color blocks to the entire blocks. Thereby, valid color pixel rate can be obtained at blocks belonging to a color region even though an image is almost monochrome but partially colored. Accordingly, the inventive image processing apparatus can appropriately determine whether the image is a color image or not.

摘要： In a digital full color image processor, color data are obtained by reading a color image with a color image sensor. An image forming mode of the color image such as background level and magnification is specified, and the image forming mode is changed according to the specified image forming mode when the color data is processed. A reference value for area discrimination is changed according to the image forming mode. Then, an area such as a black portion or a dot area in the color data is discriminated for image processing of the color data with the reference value, and the color data is processed according to the area discrimination.

摘要： An image reading apparatus comprises a photoelectric converter including three linear image sensors of red, green and blue aligned in parallel to each other along a main scan direction. When a document is scanned, a document is read by the photoelectric converter by moving it relative to the document. The moving direction is set to be a first direction, for a prescan and a second direction reverse to the first direction, for a normal scan. Analog output signals of the first to third linear image sensor are converted to digital signals. In a prescan, a selector exchanges the digital signals of the first and third linear image sensors, while in a normal scan, the selector does not exchange them. Then, a line correction section receives the digital signals of the first and third linear image sensors from the selector and the digital signals of the second linear image sensor from the analog-to-digital converter and outputs the digital signals of the first to third linear image sensors by delaying outputs of the digital signals with delay times determined in correspondence to spacial distances between positions of the three linear image sensors and a scan speed along the moving direction. Thus, image data can be read without shifts of output timings of the image data of red, green and blue.

摘要： In a digital full color copying machine, image signals of red, green and blue are converted to a value signal, and histograms of the value signal for chromatic dots and achromatic dots respectively are generated. Then, a document type, such as a color standard document, a color photograph document, a color standard document having a colored background, a black-and-white standard document, or a black-and-white photograph document, is determined automatically based on the histograms. Background level of a copy is controlled automatically at an appropriate level both for a color document and for a black-and-white document having a white background according to the document type by gradation correction of the value signal. Thus, background processing is performed irrespective of a color document or a black-and-white document.

摘要： When a monochromatic image is reproduced, a user can select desired mixing coefficients of red, green and blue in order to control gradation data for the reproduction of a monochromatic image as well as a monochromatic reproduction color. When a document is automatically determined not to be a color document, the mixing coefficients of red, green and blue are changed according to the type of the document. If a monochromatic copy mode is selected, the mixing coefficients can be set manually. Preferably, in order to help a user to select mixing coefficients, a plurality of images of monochromatic colors of various mixing coefficients of red, green and blue can be printed on a single sheet of paper.
