The color determination circuit detects hue of the color image information, and the controller decides a color component to be separated (separation color) in accordance with the detected hue. Output color by the printer is set in correspondence with the separation color. The two-color-separating circuit 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 via printer density correction circuits and , and a buffer . 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.

Image processing system which forms two-color images

The gas filter module of the invention has: a housing which has a gas inlet port at one end and a gas outlet port at another end, and which is divided into two portions in a longitudinal direction; a filter body consisting of a porous ceramics member which is loaded into the housing and through which an inflow gas passes; and a ring-like support member consisting of dense ceramics which is fittingly coupled to a step portion formed inside the housing and which is joined to the filter body. The ring-like support member is fixed via two metal O-rings to a fixing gap of the step portion of the housing.

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.

Image forming apparatus which outputs a color image by separating color

An image processing apparatus includes a plurality of memories for storing input image data in units of lines, and a processing unit for controlling write and read access operations of the memories to perform mosaic processing of an input image.

Upon gradation converting input m-bit image information into n-bit image information (m and n are integers; m&gt;n), random numbers, the maximum values of which are changed in accordance with the input values of the m-bit image information, are generated at periods of two or more pixels, and the random numbers are selectively output while switching their signs to positive/negative within the period of two or more pixels. The output signal values and the input values of the m-bit image information are added to each other, and the sum signal values are converted into n-values by a density preservation type quantization method. With this control, the problems of sweeping, texture, and the like of the conventional density preservation type quantization method can be solved without emphasizing the granularity of an image.

An image forming apparatus which varies the blending ratio by which color-seperated image signals are blended together to form a monochromatic image. The apparatus inputs a plurality of image signals which have been color-separated, and synthesizes the plurality of image signals by blending to form a monochromatic image. A density regulating mechanism regulates the density of the monochromatic image to a predetermined density level, and the apparatus varies the blending ratio of the synthesized plurality of image signals based on the predetermined density level.

An image processing apparatus of a digital copying machine or the like comprises: a color discriminating circuit to discriminate a color of an input image; a discrimination image generator to generate a color discrimination image in accordance with the discriminated color; and a trimming circuit to trim a boundary portion between the color discrimination image generated and another image. A blank portion or a boundary line is formed in the boundary portion between the color discrimination image and another image. The trimming circuit can also trim a portion in the color discrimination image in the boundary portion.

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.

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.
