Abstract
An embodiment device for synchronizing the emission and the reception of a light signal for a time-of-flight sensor comprises a power-control circuit configured to generate and transmit a power signal based on a control signal for controlling the sensor, the power signal being configured to supply power to an array of pixels of the sensor, a production module for producing a synchronization signal, which module is configured to produce the synchronization signal based on the control signal, and a switch configured to supply power to a light source of a device for emitting the light signal, the production module being further configured to transmit the synchronization signal to the switch such that the time taken to produce and transmit the synchronization signal and the time taken to generate and transmit the power signal are identical.
