Abstract
Display systems that employ input gamma dithering and dynamic backlight control. Embodiments relate to disabling input gamma dithering during periods when there is a change in the scale value by which image data is scaled due to dynamic backlight control. In this manner, input gamma dithering is selectively applied only during those times when data scaling due to dynamic backlight control is constant.
