    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: 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 device for processing values corresponding to measurement of pixels, includes an input inputting a j th primary density information X.sub.j representing density information of the j th pixel of an image, where the j th pixel includes a part which overlaps the previous (j-1)th pixel. A calculator calculates the j th secondary density information .DELTA.X.sub.j which represents the density information of the part of the j th pixel which does not overlap the (j-1)th pixel, on the basis of at least the j th primary density information X.sub.j and of the previously calculated secondary density information. A memory stores at least one of the j th primary density information X.sub.j and the j th secondary density information .DELTA.X.sub.j. The device can be used in a facsimile system and a data processing system.
