Abstract

An information handling system includes a display device, a camera, and a processor. The camera captures an image including first and second observers in a field of view in front of the display device. Based on the captured image, the processor determines a first location of the first observer and a second location of the second observer. Based on the first and second locations, the processor determines a first set of pixels located within a primary field of view for the first observer, and a second set of pixels located within a second field of view for the second observer. The processor calculates a viewing legibility adjustment for the second set of pixels. Based on the viewing legibility adjustment, the processor adjusts a contrast ratio for the second set of pixels to below a viewing threshold level.
