    摘要: An image processing apparatus includes an image extracting unit, a vector information generating unit and a color information adding unit. The image extracting unit extracts an image to be vectorized from a multilevel image as a binary image. The vector information generating unit vectorizes the binary image extracted by the image extracting unit to generate vector information. The color information adding unit adds color information to the vector information generated by the vector information generating unit.

    摘要: An index signal and a delta signal are generated from an input pixel value, and then, inputted to an input buffer by every predetermined pixel to be processed. A controlling unit compares the index signal in the input buffer with a tag (index signal) in a coefficient cache. When they coinside with each other, the controlling unit reads out the corresponding coefficient from the coefficient cache and supplies the same to an interpolating unit. The interpolating unit simultaneously receives the delta signal and supplies the keeping color data to an output buffer. Thereafter, the interpolating unit accesses to the coefficient storing memory by using an index signal that does not coinside with either one of cache-tag (index signal) to obtain a coefficient, and similarly, interpolatively generates color data. Data of converted color is outputted from the output buffer in the order of inputting the pixel. A color converting device of the present invention can perform a color conversion with high precision without increasing a reading-out band of a coefficient table for a color conversion.
