1. A method for measuring ambient light, the method comprising:
successively synchronizing optical signal acquisition phases with extinction phases of a disruptive light source, wherein the disruptive light source periodically provides illumination phases and the extinction phases;
receiving an external control signal representative of the extinction phases of the disruptive light source;
accumulating, in each acquisition phase, photo-generated charges by at least one photosensitive pixel comprising a pinned photodiode;
transferring the accumulated photo-generated charges to an integration node; and
integrating, for each pixel, the transferred charges on the integration node during a series of the successive acquisition phases.
