发明名称 Color converting method and apparatus and image processing method and apparatus
摘要 It is an object to provide color converting method and apparatus and a display control apparatus, in which frequencies of colors which are inputted into a lookup table and the contents of the lookup table are changed in accordance with the frequencies of the colors, thereby a color reproducibility is further improved. In a color converting apparatus for converting inputted color information by using a rewritable lookup table (LUT), occurrence frequencies of output color data of the LUT are counted by using a decoder and a counter, and on the basis of the occurrence frequencies of each color which were calculated, an MPU obtains table data which makes a dispersion of the occurrence frequencies of the output color data of the LUT 100 lie within a predetermined range. The resultant table data is written into an address in the LUT.
