摘要： An electronic camera comprises a first chromaticity data memory to memorize chromaticity data of at least three different color chips, each color chip having a vector independent of others in color space; a CPU to determine a converting matirx to convert chromaticity data of photographed image data corresponding to the three different color chips so as to conform with the memorized chromaticity data of the three different color chips; and a converter to convert the image data by the determined converting matrix.

摘要： A color image reproducing device comprising a scanner, a color value memory, a scanner signal memory, a conversion element, and the adjusting element. Each memory stores standard color values derived from reference color values and standard scanner signals derived from reference scanner signals. The reference color values and reference scanner signals are obtained by measuring both by a colorimeter and by scanning of color patches. The color values are derived from measured scanner signals of an original based upon correspondence between standard color values and standard scanner signals. Finally, the device adjusts relative color balance by controlling the intensity of outputs based upon the color values.
