Patent ID: 7965429

Claim:
An apparatus for performing color plane adjustment, the apparatus comprising: a set of inputs for receiving a first input value and a second input value in a color space; a controller including a color plane adjustment component operative to adjust the first input value and the second input value by amounts that depend on respective distances of the first input value and the second input value from a neutral value in the color space; and a set of outputs for outputting the adjusted first and second input values, wherein the color plane adjustment component is operative to adjust the first input value by evaluating the first input value to determine a difference between the first input value and the neutral value, wherein the neutral value is a neutral point of the color plane space, wherein an amount by which the first input value is adjusted decreases as the difference between the first input value and the neutral value increases, and wherein an amount by which the first input value is adjusted increases as the difference between the first input value and the neutral value decreases, and wherein the color plane adjustment component is operative to adjust the second input value by evaluating the second input value to determine a difference between the second input value and the neutral value, wherein an amount by which the second input value is adjusted decreases as the difference between the second input value and the neutral value increases, and wherein an amount by which the second input value is adjusted increases as the difference between the second input value and the neutral value decreases.
