Abstract
A pixel circuit includes: a photodetector, a signal adjustment circuit and a switch circuit. The photodetector is employed for generating an output signal in response to light that is incident thereon. The signal adjustment circuit is coupled to the photodetector, and employed for selectively adjusting the output signal to allow the output signal to have a plurality of different logarithmic functions in respect to an intensity of the light. The switch circuit is coupled to the signal adjustment circuit and the photodetector, and employed for coupling the photodetector to the signal adjustment circuit.
