Patent ID: 8599455

Claim:
An apparatus for performing color plane adjustment, the apparatus comprising: an input configured to receive an input value in a color space, the input value comprised of at least a first color component input value and a second color component input value; a controller including a color plane adjustment component configured to: determine a difference between the first color component input value and a gray value along a gray axis of values in the color space, wherein the gray axis is a line within the color space that is defined as separate from and in relation to axes that comprise the color space; determine a difference between the second color component input value and the gray value; access a first color component adjustment factor based on the difference between the first color component input value and the gray value; adjust the first color component input value by the first color component adjustment factor, wherein the first color component adjustment factor increases the first color component input value as the difference between the first color component input value and the gray value is smaller, and decreases the first color component input value as the difference between the first color component input value and the gray value is greater; access a second color component adjustment factor based on the difference between the second color component input value and the gray value; adjust the second color component input value by the second color component adjustment factor, wherein the second color component adjustment factor increases the second color component input value as the difference between the second color component input value and the gray value is smaller, and decreases the second color component input value as the difference between the second color component input value and the gray value is greater, and an output configured to output the adjusted first color component input value and the adjusted second color component input value.
