Patent ID: 7945092

Claim:
A pixel processor comprising: a data processing means which converts a luminance component in a direction of a luminance axis through color vision conversion processing in accordance with a selected component in a direction of a selected axis selected from a first component in a direction of a first axis and a second component in a direction of a second axis, wherein: the luminance component, the first component, and the second component constitute pixel data designating position data in a uniform color space indicated by three orthogonal coordinate axes of the luminance axis representing luminance, and the first axis and the second axis representing a chromaticness index; and the color vision conversion processing is conducted to decrease the luminance component in the direction of the luminance axis or increase the luminance component in the direction of the luminance axis alternatively in either case where the selected component in the direction of the selected axis is greater than a first predetermined value or where the selected component in the direction of the selected axis is smaller than a first predetermined value.
