<p><P>PROBLEM TO BE SOLVED: To solve the problem of hue shift in red having intermediate saturation while making full uses of the advantages of a display for displaying bright red having high saturation when displaying video images based on video signals conforming to standards (sRGB standards etc.) of a color reproduction range smaller than the range of a large color gamut display. <P>SOLUTION: A video processing circuit 2 corrects colors of a predetermined correction target color range partly including a red hue reference range as a center portion of a color range of an iso-hue ranging from achromatic colors having the lowest saturation to red having the highest saturation in an expanded color reproduction range and not including red having the highest saturation in the expanded color reproduction range so that the hue thereof may change to a hue akin to yellow in the expanded color reproduction range. In that case, the circuit executes correction so that the hue of the red hue reference range may change into the red hue in the color reproduction range conforming to the sRGB standards and the hue change rate into the hue akin to yellow may be smaller in a color having a distance not akin to the red hue reference range than a color having a distance close thereto. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
