Abstract: A method and apparatus are explained for performing white point color adjustment for a display device. This can be done by obtaining a value of an ambient light sensor, determining whether to make a white point adjustment, and, for a dynamic white point adjustment, using the value from the ambient light sensor in performing white point adjustment toward target color coordinates. A white point might be set equal to the target color coordinates, but might also remain unchanged for small ambient light changes or ambient light outside a region of interest. The white point might be changed to the target color coordinates in multiple steps. Various parameters might be used that can be varied to vary behavior of the white point adjustment.
