An active photosensing pixel is disclosed, in which a two-terminal photosensing transistor has a first terminal coupled to a first node, a second terminal coupled to a first selection line and a control terminal connected to the second terminal. A driving transistor has a first terminal coupled to a first reference voltage, a second terminal coupled to an output line and a control terminal connected to the first node. A reset transistor has a first terminal connected to the first node, a second terminal coupled to a second reference voltage and a control terminal coupled to a second selection line.
