Abstract
An optical sensing circuit includes a first light sensor, a second light sensor, a third light sensor, a capacitor, and a sampling circuit. The first light sensor, the second light sensor, and the third light sensor are respectively covered by a first color filter, a second color filter, and a third color filter. The first light sensor is coupled to the capacitor, the sampling circuit, and the third light sensor. The second light sensor is coupled to the first light sensor and is configured to receive a first sensing signal. The third light sensor is coupled between the first light sensor and a voltage source.
