Abstract:
1. In a display system operable to display each of a plurality of pixels at a visual output intensity relative to an output display device according to a corresponding pixel input value, a method for determining device-specific information for pixels to obtain an optimal display of images on an output display device, the output display device having one or more color planes, the method comprising determining a set of device-specific pixel input values, based on user input, that will cause the display system to display a corresponding set of target visual output intensities relative to the output display device, the determining step including displaying a control region and a reference region on the output display device, the reference region being defined by a plurality of reference pixels, input values of the reference pixels being selected so that an average of visual output intensities of the reference pixels is a target visual output intensity, the control region being defined by a plurality of control pixels, each of the control pixels having a common pixel input value, evaluating the control region and reference region for each color plane of the display device, and adjusting the common pixel input value for the control pixels until a match is achieved between an appearance of the reference region and an appearance of the control region for each color plane, such that target visual output intensities are achieved, wherein the control region is in proximity to the reference region.
