Abstract
Mechanisms for compensating for backlight conditions in a scene for use in an image capture device that includes a flash and a flash control signal for activating the flash when the flash control signal is asserted are described. First, a meter matrix for a scene that includes a plurality of points, where each point can include brightness information and distance information, is generated. Second, a flash control signal is selectively asserted based on the meter matrix.
