Title
(EN) SYSTEMS AND METHODS FOR CREATING A FULL-COLOR IMAGE IN LOW LIGHT
(FR) SYSTÈMES ET PROCÉDÉS POUR CRÉER UNE IMAGE EN PLEINE COULEUR PAR FAIBLE LUMINOSITÉ
Abstract
(EN)
Imaging devices (100) and methods (3700) for generating a color image (3720) from a low-light scene. A method includes producing a first light channel having unfiltered light and a second light channel having light filtered by a first filter (3706). The method includes producing a first information channel (3708) and a second information channel (3710) by a radiation sensitive sensor (3702). The first information channel (3708) includes first brightness information corresponding to the first light channel and the second information channel (3710) includes second brightness information corresponding to the second light channel. The method includes assigning, by an image processor (112), the first brightness information to a first color channel (3714) and the second brightness information to second color channel (3716). The method includes assembling (3718), by the image processor (112), a full-color image stream (3720) from the first color channel and the second color channel. The method includes outputting the full-color image stream (3720).

L'invention concerne des dispositifs d'imagerie (100) et des procédés (3700) pour générer une image couleur (3720) à partir d'une scène à faible luminosité. Un procédé comprend la production d'un premier canal de lumière ayant une lumière non filtrée et d'un second canal de lumière ayant une lumière filtrée par un premier filtre (3706). Le procédé comprend la production d'un premier canal d'informations (3708) et d'un second canal d'informations (3710) par un capteur sensible au rayonnement (3702). Le premier canal d'informations (3708) comprend des premières informations de luminosité correspondant au premier canal de lumière et le second canal d'informations (3710) comprend des secondes informations de luminosité correspondant au second canal de lumière. Le procédé comprend l'attribution, par un processeur d'image (112), des premières informations de luminosité à un premier canal de couleur (3714) et des secondes informations de luminosité à un second canal de couleur (3716). Le procédé comprend l'assemblage (3718), par le processeur d'image (112), d'un flux d'image en pleine couleur (3720) à partir du premier canal de couleur et du second canal de couleur. Le procédé comprend l'émission du flux d'image en pleine couleur (3720).
