Abstract
A pixel includes: a detection node; a first normally on transistor connected between the detection node and a rail for applying a first potential; and a second transistor whose gate is connected to the detection node. An image sensor includes a plurality of the pixels and a control circuit configured to apply, during for a phase of initializing the detection node, the first potential to the gate of the first transistor.
