Abstract: 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.

Abstract: A system for acquiring images in color and near-infrared, comprising: a matrix sensor, which comprises first, second, and third types of pixels sensitive to respective visible colors and a fourth type of panchromatic pixels sensitive in the near-infrared; and a signal processing circuit configured to reconstruct first and second sets of monochromatic images, a panchromatic image, a color image from the images of the first set and from the panchromatic image, and at least one image in the near-infrared from the images of the second set and from the panchromatic image. A visible-near-infrared bispectral camera comprises such an acquisition system and method implemented by means of such a camera.
