    摘要: Image distortion is corrected in a color printer wherein print units for a plurality of colors are aligned to form a color image by superposing images formed by the print units. A quantity of image distortion is detected, and correction data of main scan address and subscan address are calculated and stored according to the detected image distortion for each main scan address. When input color image data are corrected, printing position is corrected in combination of address change with density interpolation. When the correction data exceeds the maximum correction range, the correction data are replaced by the maximum in the correction range for distortion correction. Further, in the image data correction, after the image data are converted to data having a smaller number of gradation levels, the data are delayed according to the serial arrangement of the print units. Then, the delayed data are converted again for printing.

    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.

    摘要: In an image processing apparatus, a color image is read with pixels aligned along a direction to provide first color data on the color image. The first color data includes red, green and blue data at each pixel. A first operator calculates first chroma data according to the first color data. On the other hand, a phase shift device generates second color data by shifting a phase of red data and by shifting a phase of blue data in the first color data, and a second operator calculates second chroma data according to the second color data. A selector selects chroma data having a lower chroma, and a black edge of a character a the color image is discriminated according to the selected chroma data.

    摘要: In an image reading apparatus, the standard data for the normalization of the image read data are obtained with use of a line memory of one line from the standard data of a plurality of lines. The white level data and the black level data are used for the normalization. The weight average of the input data of the standard data received successively one line by one converges gradually. The converged average is used for the correction of read data of an image, and the effect of image noises is reduced and the image read data is normalized at a high precision. In a continuous reading, only the white level may be updated for shortening the time for reading.

    摘要: The characteristics such as hue, saturation, edge portion or flat portion of image data are decided for each pixel based on read data of three primary colors. The decision is performed on the data which have been subjected to spatial filtering, and the processing of the image data such as smoothing or edge emphasis are changed according to the detected characteristics. For example, the masking coefficient is selected according to the detected hue. The color data is decreased and the black data is generated, according to the detected saturation. The edge is decided only when the sign of the gradients of the three color data agree with each other. Further, edge detection quantity is detected in the edge decision and the edge emphasis or the smoothing is performed by comparing the edge detection quantity with threshold values only when the edge is detected.
