The present invention relates to a device for classifying a light source, comprising:



a sensor adapted to receive a luminous flux emitted by a light source, the sensor comprising a plurality of pixels grouped in sets, each set comprising a first pixel and a second pixel 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,
a computer configured to compare the first and second signals and to classify the emitting light source according to the result of the comparison.
