Abstract
Systems, methods, and devices are provided for generating a tone mapping function used in adjusting the power consumed by a backlight of an electronic display. One such method includes sampling an image frame in framebuffer space and generating a tone mapping function in linear space. The tone mapping function may have at least two portions: a nondistorting portion that does not to distort pixels to which it applies when an intensity of a backlight of the electronic display is modified and a distorting portion that does distort pixels to which it applies when the intensity of the backlight is modified. Thereafter, the intensity of the backlight may be modified based at least in part on the nondistorting portion of the tone mapping function, the tone mapping function converted to framebuffer space, and the tone mapping function applied to the image frame or a subsequent image frame.
