Abstract
An apparatus includes a complementary metal oxide semiconductor (CMOS) image sensor, an infrared light generating circuit, and a processor circuit. The CMOS image sensor includes a plurality of picture elements, where light integration begins on all of the picture elements simultaneously in response to a first control signal. A duration, an intensity, or both a duration and an intensity of infrared illumination produced by the infrared light generating circuit is controlled by a second control signal. The processor circuit is enabled to generate the first control signal and the second control signal. A period of the infrared illumination is shorter than an integration period of the CMOS image sensor.
