    摘要: When a pixel block of a color image is coded, the coding is performed by taking the correlation between lightness and chromaticity into account. More specifically, the color data within the pixel block is separated into lightness and chromaticity. Lightness is coded by being subjected to an orthogonal transformation. The coding of chromaticity is performed by detecting the average value of chromaticity and the amplitude of chromaticity of a pixel block, calculating the ratio of chromaticity amplitude to lightness amplitude and then coding chromaticity based upon the calculated ratio and the average value of chromaticity.

    摘要: An image processing apparatus inputs image signals by a plurality of pixels in synchronism with a predetermined clock; designates a reduction ratio of an image represented by the input image signals; cumulatively adds a value on the basis of the inverse of the designated reduction ratio in synchronism with the predetermined clock and holds a value of predetermined number of lower significant digits of the added value; and thins out and interpolates image signals input by the input means in accordance with whether or not the value held by the addition means exceeds a predetermined value.

    摘要: An image processing apparatus judges the degree of similarity between entered image data and characterizing data of a special image (an image containing a special original such as a bank note or negotiable instrument) prepared in advance, generates data indicative of the degree of similarity and integrates similarity data in two-dimensional space while subjecting the entered image data to image processing conforming to the results of integration. For example, image data of an area for which the degree of similarity resulting from integration indicates a certain value is forcibly converted into data having maximum density.

    摘要: An image processing apparatus is provided with an input of multivalued image data, converts the inputted multivalued image data into binary image data, generates color data based upon the binary image data resulting from the conversion, judges identity between the generated color data and color data of a plurality of different specific images, and outputs the binary image data resulting from the conversion if non-identity is judged. If identity is judged to exist, however, output of the binary image data resulting from the conversion is halted.
