1. A device for classifying a light source comprising:
a sensor adapted to receive a luminous flux emitted by at least one light source, the luminous flux being received on the sensor in the form of a spot, the sensor comprising a plurality of pixels grouped into sets, each set comprising at least a first pixel and a second pixel, the second pixel being adjacent to the first pixel,
each first pixel being adapted to generate a first signal relating to a first portion of luminous flux in a first spectral band received by said first pixel,
each second pixel being adapted to generate a second signal relating to a second portion of luminous flux in a second spectral band received by said second pixel, the second spectral band being different from the first spectral band,
a unit for controlling the size and shape of the spot so that the spot extends over at least one set of pixels of the sensor, and
a computer configured to compare the first and second signals and to classify the emitting light source according to the result of the comparison.
