    摘要： An image processing apparatus having a first mode for processing electrical signals by a pre-scan operation and a second mode for processing electrical signals by a main scan operation. The first mode forms a histogram on the basis of electrical signals obtained by the pre-scan operation, and detects predetermined feature points from the formed histogram. A table is formed for converting signal levels of the electrical signals according to the detected predetermined feature points of the histogram based on the image type of the original. The second mode generates reproduction signals from electrical signals obtained by the main scan operation in accordance with the table.

    摘要： An image processing apparatus for converting color images into monochromatic pattern images. The image processing apparatus includes: means for detecting the area of a color image; means for converting a color image into a monochromatic pattern image; and control means for varying such image processing in accordance with the result of detection made by the means for detecting the area. When a thin line is detected in a color area, the method of processing is determined based on the width of the detected thin line. For example, when the width of the thin line is smaller than a predetermined value, the area of such thin line may be outputted as a plain image instead of a pattern image so that it may easily be seen or recognized. The contour of a color area may be made conspicuous by combining a plain image and a pattern image.

    摘要： An image processing apparatus in which a color identifier identifies the color of an input image based on an input color-image signal. A luminance detector detects luminance information in the input color-image signal. An image generator generates a predetermined pattern which is indicative of the color identified by the color identifier. A measurement device measures the luminance distribution of the detected luminance signal which is outside an area in which color is identified by the color identifier. The output density of the input color-image signal is set in accordance with the measured luminance distribution, and an output monochromatic image is produced in which colors of the input image are identified by the predetermined patterns.

    摘要： A two-color separating circuit separates an input image signal into two color signals R and K. In conformity with a color signal indicating the maximum value of the separated color signals, a color-mixture correcting circuit corrects the other color signal. The density of the color pixel formed by the corrected color signal is predicted, and the difference between the result of prediction and the color signal before correction is distributed among pixels of the same color surrounding this pixel. Accordingly, it is possible to provide an image processing apparatus for supplying an image forming apparatus, which collectively forms images of two colors, with an image signal subjected to processing capable of performing excellent color mixing without lowering the density of whichever of the two color-component images is formed last.

    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.
