Abstract
A time-division multiplexing fill light imaging method includes alternately generating a visible light frame and a fill light frame by using an image sensor, where the visible light frame is an image frame generated when the image sensor receives visible light but does not receive fill light, and the fill light frame is an image frame generated when the image sensor receives fill light, and combining a visible light frame and a fill light frame that are adjacent or consecutive, to obtain a composite frame.
