Abstract
A camera system includes a camera, an illumination source, a first light sensor having a first light sensor output, and a second light sensor having a second light sensor output. A processor has inputs coupled to the camera's output, the first light sensor output, and the second light sensor output, and the processor has an output coupled to the input of the illumination source. The processor receives a first light signal from the first light sensor output, receive a second light signal from the second light sensor output, determine a first weight for the first light signal and a second weight for the second light signal based on a difference between the first and second light signals, calculate a weighted average of the first and second light signals using the first and second weights, and determine whether to turn on the illumination source based on the weighted average.
