1. A method for reducing power consumption of a display, the method comprising: determining a first scale factor based on sampled pixel values of one or more frames; dimming a backlight of the display by the first scale factor; increasing pixel values to be displayed on the display by a second scale factor inversely proportional to the first scale factor; and clamping the pixel values to a maximum threshold, wherein the second scale factor is greater than an inverse of the first scale factor to compensate for the clamping.
