Abstract
An image sensing system includes: a light emitting device; a pixel configured to capture an optical signal and to convert the optical signal into an analog image signal; an analog circuit configured to selectively filter the analog image signal; an analog-to-digital converting circuit configured to convert the analog image signal to a digital image signal; a digital circuit configured to receive the digital image signal and to switch the light emitting device on and off; wherein the digital image signal includes a dark image frame if the optical signal is captured when the light emitting device is off; wherein the digital image signal includes an effective image frame if the optical signal is captured when the light emitting device is on and the analog circuit is configured to filter the analog image signal; and wherein the digital image signal includes a punctured image frame if the optical signal is captured when the light emitting device is on and the analog circuit is not configured to filter the analog image signal.
