| Abstract: | During the color gamut transformation process,the quantization error and the truncation error existed.As a result,the deviation between the transformed color gamut and the standard color gamut was produced,if the deviation was beyond the color tolerance,the uniformity of the screen color will be affected.This paper presented the correlations of quantization and the different gray value for color gamut according to the values the relationship of the quantization precision. |

| Keywords: | color matching algorithm quantization precision gray value the color difference |
