Abstract
A pixel circuit includes a front-end circuit, a signal storage circuit, and an output circuit. The signal storage circuit is coupled to the front-end circuit, and the output circuit is coupled to the signal storage circuit. The front-end circuit is arranged to generate pixel signals. The signal storage circuit is arranged to store the pixel signals generated by the front-end circuit, wherein when the pixel circuit is selected for performing a read-out operation, the pixel signals stored in the signal storage circuit are pulled up from original voltage levels to other voltage levels higher than the original voltage levels according to a voltage increment applied to a control voltage. When the pixel circuit is selected for performing the read-out operation, the output circuit generates output signals on an output terminal according to the other voltage levels, respectively.
