摘要:
An image processing apparatus includes an image processing unit, a counter, and a determining unit. The image processing unit processes image data between first and second color values of an input image. The counter counts generation frequencies of the respective color values of the input image. The determining unit determines the first and second color values on the basis of the count result obtained by the counter.

An image forming apparatus includes an input unit, a color discriminating unit, a pattern generating unit, and an image forming unit. The input unit inputs an image having a plurality of colors. The discriminating unit discriminates the colors of the image input from the input unit. The pattern generating unit generates a pattern image in accordance with the discrimination result obtained by the discriminating unit. The image forming unit forms the pattern image, generated by the pattern generating unit, on a recording medium. The image forming unit forms the pattern image in different colors in accordance with the discrimination result obtained by the discriminating unit.

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.

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.

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.

The present invention is intended to provide an image processing apparatus capable of two-color output representation in high accuracy even with a full-colored original. A color original is entered by an input means for prescan, a density distribution with respect to a hue is obtained for each electric signal of color image information, and a characteristic point of the color original image is obtained from the result of the density distribution. The two-color separation means separates a full-colored original to two colors free from the same color representation according to the information of the characteristic point obtained.
摘要:
There is disclosed an image processing apparatus capable of identifying and converting a predetermined color in the input image into a predetermined density, whereby the color in the original image can be identified in a monochromatic image by the density. The apparatus is provided with a discrimination unit for identifying a predetermined color in the input image, a first image processing unit for applying a first image processing to the input image according to the result of discrimination by the discrimination unit, a second image processing unit for applying a second image processing to the input image, and a control unit for invalidating the second image processing in an area in which the image processing is conducted by the first image processing unit.

An electromagnetic actuator having: a stator and a movable member disposed in a central hole of a coil member of the stator movable in an axial direction; a coupling rod fixed to the movable member; and an elastic stopper having a ring shaped sealing unit at its outer periphery part, a first stopper unit at its center part, a coupling unit that mutually couples the sealing unit and the first stopper unit, and second stopper units located radially between the sealing unit and the first stopper unit at respective circumferential positions. The sealing unit is compressed between the bottom wall of a housing and a lid member to form a sealing mechanism that fluid-tightly close an opening of an adjustment hole. The first stopper unit axially faces the coupling rod bottom with a first separation distance, and the second stopper units axially face the movable member bottom with a second separation distance greater than the first.
