Zusammenfassung:There is provided a pixel circuit including a first circuit and a second circuit. The first circuit is used to output a first voltage associated with exposure intensity. The second circuit is used to output a second voltage associated with exposure time interval. The processor multiples the first voltage to a ratio between a reference voltage and the second voltage to obtain an actual light intensity, wherein the reference voltage is a voltage value outputted by the second circuit of a dummy pixel.
