Abstract
An electronic device balances gain and exposure at an imaging sensor of the device based on detected image capture conditions, such as motion of the electronic device, distance of a scene from the electronic device, and predicted illumination conditions for the electronic device. By balancing the gain and exposure, the quality of images captured by the imaging sensor is enhanced, which in turn provides for improved support of location-based functionality.
