Abstract:
Aspects of the present invention relate to systems and methods for performing white balance operations for an LED display backlight. Some aspects related to an iterative process wherein display backlight luminance and color are sampled at an intermediate resolution between the resolution of the LED backlight and the resolution of the LCD display. Some aspects relate to a process wherein r, g and b driving value differences are determined using a deconvolution technique.
