Citation: US Patent 7,858,912 B2, 2010
Abstract: An optical sensor has at least one pixel that generates an output voltage that changes at a rate dependent on the light intensity incident on the pixel. The time for the pixel output voltage to change from a first predefined level to a second predefined level is measured, so as to produce an output indictative of the incident light intensity.
