<P>PROBLEM TO BE SOLVED: To provide an image processor and an image processing method for efficiently specifying and reproducing neutral colors such as gradation. <P>SOLUTION: The image processor has a color map 143 in which monochromatic color codes expressing specific colors and neutral color codes expressing colors except for the specific colors are defined, an input means 12 for inputting image data 20 expressed by using the color map 143 and a conversion means 14 for using the input image data 20 and the color map 143, outputs color values indicated by the monochromatic color codes when object pixels of the image data 20 are specified by the monochromatic color codes of the color map 143 and outputs color values computed by an interpolation computation by positions of the object pixels from two monochromatic color codes indicated by the neutral color codes and two pixel positions corresponding to them when the object pixels are specified by the neutral color codes of the color codes. <P>COPYRIGHT: (C)2007,JPO&INPIT |
