Abstract
A light sensor arrangement is used to detect ambient light conditions. According to an example embodiment, a light detector arrangement (e.g.,) generates an output in response to light incident thereupon. An averaging-type circuit (e.g.,) samples the generated output for overlapping time intervals, and combines the sampled output to form a new output that characterizes the incident light. The overlapping time intervals(e.g.,-) are chosen such that the new output is generally flicker-free for incident light generated using one of at least two different power supply frequencies.
