摘要
There is provided a BJT pixel circuit including a BJT transistor, a photodiode, a first storage capacitor and a second storage capacitor. The first storage capacitor is configured to discharge, via the BJT transistor, to a first output voltage in a first exposure time of the photodiode. The second storage capacitor is configured to discharge, via the BJT transistor, to a second output voltage in a second exposure time of the photodiode.
