    Abstract: The disclosure relates to a method for detecting the presence of an object near a detection device, comprising: reverse biasing single photon avalanche photodiodes, at a bias voltage greater than a breakdown voltage of a PN junction of each photodiode, emitting pulses of an incident photon beam, detecting photodiodes which avalanche trigger after the reception by the photodiode of at least one photon of a reflected photon beam produced by a reflection of the incident beam on an object near the detection device, determining the object presence as a function of the existence of at least one avalanche triggering in one of the photodiodes, and selecting a number of photodiodes to be reverse biased in relation to the detection device, as a function of a load of a circuit for generating the bias voltage.

    Abstract: A device includes an image sensor and a circuit for controlling the sensor. The control circuit is configured control the device in a first operating mode and second operating mode. In the first operating mode images acquired by the sensor are output. In the second operating mode, no images are provided, but a selected subassembly of pixels of the image sensor are read and image data therefrom is processed to provide an ambient luminosity value.
