    摘要: An image information processor for producing a high-quality output image by emphasizing the contour portions of a character, a photograph and others and by preventing the generation of a Moire patterns in a dot region, for preventing an increase in the amount of codes, and for making it unnecessary to set desired binarization processing for each original, is provided. The processor includes a unit for scanning the original to convert each pixel data into an electric signal, a unit for controlling the start of image processing, a filter for carrying out enhancement processing among a plurality of pixels arranged in oblique directions after smoothing processing has been carried out among a plurality of contiguous pixels arranged in scanning and traverse directions, and a unit for carrying out at least one of binarization and binarization capable of realizing pseudo tone expression. According to the above construction of the image information processor, a unit for preventing the generation of a Moire pattern in the dot region of an original and for carrying out contour enhancement for the character/photograph region of the original can be formed of simple hardware capable of performing a high-speed operation, a clear binary output is obtained, and an increase in transmission time is prevented.

    摘要: In a high-speed image scanner, a driving method is proposed which needs no timing adjustment between the sensor driving pulse and the motor drive pulse required when the motor shifts from an accelerated state to a constant-speed state. The period of the sensor driving pulse is selected to be equal to or 1/N (N=integer) of that of the motor drive pulse at the time of constant-speed operation, and the phases of the sensor driving pulse and motor drive pulse are controlled independently of each other. Thus, even though the sensor driving pulse and the motor drive pulse are out of good timing, each line of the image can be surely read.

    摘要: It is possible to compatibly set multiple “dropout” color ranges and “non-dropout” color ranges and uniquely determine a dropout boundary. An object of the present invention is to greatly conserve maintenance cost of adding a new dropout form after apparatus operations. A conventional technology aims at assuring relation to a predetermined color region, determining the presence or absence of contention, or uniquely settling a dropout boundary. The present invention provides a means for supplying levels to a “dropout” color range and a “non-dropout” color range. A registered color range histogram can be quasi-three-dimensionally visualized so that an operator can make adjustment by viewing a contention determination result and an image.

    摘要: A distance measuring technology is capable of stably and accurately performing measurement of the distance to the distance to an object without use of a highly accurate focus control mechanism. The distance measurement is performed by an apparatus having a mask for restricting light so as to pass light through two or more different light passing positions; a lens system for focusing the light that has passed through the mask; an image taking-in means for taking in images from the light focused by the lens system; and a distance calculating unit for calculating a distance from an imaging element to an object using the taken-in images. The mask restricts the light so that the light is able to pass through only specified positions.
