Abstract
A pixel comprises a photodetector and a control circuit. The pixel is provided with an output terminal designed to connect an analysis circuit. The photodetector is configured to have two different operating modes associated with different biasing conditions. A switch connecting the photodetector to the output terminal of the pixel and a circuit for a connecting/disconnecting the control circuit with the output terminal of the pixel and with the photodetector allow to switch between the two operating modes. A comparator compares the voltage across the capacitive load with respect to a threshold value and outputs first and second signals according to the comparison. The comparator is connected to the circuit for connecting/disconnecting the control circuit and to the switch.
