Title (EN) SYSTEM AND METHOD FOR ACQUIRING VISIBLE AND NEAR INFRARED IMAGES BY MEANS OF A SINGLE MATRIX SENSOR
(FR) SYSTEME ET PROCEDE D'ACQUISITION D'IMAGES VISIBLES ET DANS LE PROCHE INFRAROUGE AU MOYEN D'UN CAPTEUR MATRICIEL UNIQUE
Abstract:
(EN) System for simultaneous acquisition of colour and near-infrared images comprising a single matrix sensor comprising a first, second and third type of pixels sensitive to respective visible colours and a fourth type of pixel, panchromatic, these pixels also being sensitive in the near-infrared; and a circuit for processing signals configured to: reconstruct a first set of monochromatic images on the basis of signals generated by the pixels of the first, second and third type, respectively; reconstruct a panchromatic image on the basis of signals generated by the pixels of the fourth type; reconstruct a second set of monochromatic images on the basis of signals generated by the pixels of the first, second and third type, and of said panchromatic image; reconstruct a colour image on the basis of the images of the first set and of the panchromatic image, and reconstruct at least one near-infrared image on the basis of the images of the second set and of the panchromatic image. Visible - near-infrared bi-spectral camera comprising such an acquisition system and method implemented by means of such a camera.
(FR) Système d'acquisition simultanée d'images en couleurs et dans le proche infrarouge comprenant un capteur matriciel unique comprenant un premier, deuxième et troisième type de pixels sensibles à des couleurs visibles respectives et un quatrième type de pixel panchromatique, ces pixels étant aussi sensibles dans le proche infrarouge; et un circuit de traitement de signaux configuré pour : reconstruire un premier ensemble d'images monochromatiques à partir de signaux générés par les pixels du premier, deuxième et troisième type, respectivement; reconstruire une image panchromatique à partir de signaux générés par les pixels du quatrième type; reconstruire un deuxième ensemble d'images monochromatiques à partir de signaux générés par les pixels du premier, deuxième et troisième type, et de ladite image panchromatique; reconstruire une image en couleurs à partir des images du premier ensemble et de l'image panchromatique, et reconstruire au moins une image dans le proche infrarouge à partir des images du deuxième ensemble et de l'image panchromatique. Caméra bi-spectrale visible - proche infrarouge comprenant un tel système d'acquisition et procédé mis en œuvre au moyen d'une telle caméra.
