Patent ID: 7710432

Claim:
A method for adjusting the appearance of images rendered to a display device, the method comprising obtaining an RGB profile associated with a display device, applying a selective tristimulus correction to device-independent coordinates of the RGB profile using a piecewise linear correction function of the linear RGB space associated with the RGB profile and converting images rendered to the display device with the adjusted RGB profile, wherein the piecewise linear correction function is defined such that a maximum of the piecewise linear correction function occurs at a boundary condition of the corresponding linear RGB space and the piecewise linear correction function is linearly reduced to zero or approximately zero as values in the corresponding device-dependent color space approach either a different boundary condition or a neutral axis; wherein the piecewise linear correction function is dependent on all of the linear device-dependent coordinates associated with the RGB profile; and wherein the piecewise linear correction function varies as the hue, saturation, and brightness of the corresponding device-dependent coordinates vary.
