Abstract

In some examples, a light source is controlled to output light. A sensor element outputs first detections responsive to a combined light comprising ambient light and the light output by the light source when the light source is on, and outputs second detections responsive to ambient light when the light source is off. The first detections are routed to a first accumulator to produce a first accumulation, and the second detections are routed to a second accumulator to produce a second accumulation. An adjusted output image is generated by removing a contribution of the second accumulation from the first accumulation.
