Abstract
A pixel circuit includes a plurality of pixel units, and one of the pixel units includes a photosensor, a readout circuit, and a switch circuit. The readout circuit is coupled to a supply voltage and the photosensor, which includes a floating diffusion node for storing data of the photosensor and an output node for outputting data of the floating diffusion node. The switch circuit is coupled between the photosensor and a tail node, wherein the tail node is coupled to the floating diffusion node of another pixel unit.
