Abstract: A pixel circuit including a photodiode, a first storage capacitor and a second storage capacitor is provided. The first storage capacitor discharges to a first output voltage in a first exposure time and to a third output voltage in a third exposure time. The second storage capacitor discharges to a second output voltage in a second exposure time and to a fourth output voltage in a fourth exposure time. The first and second exposure times are included in a first frame period. The third and fourth exposure times are included in a second frame period. The second frame period is a next frame period of the first frame period. In the first frame period, the first exposure time is subsequent to the second exposure time. In the second frame period, the third exposure time is prior to the fourth exposure time.
