Title
(EN) METHODS AND SYSTEMS FOR IMAGE CAPTURE
(FR) PROCÉDÉS ET SYSTÈMES DE CAPTURE D'IMAGE
Abstract
(EN)
The present disclosure relates to image capture systems and methods. The image capture method may include obtaining first color image data including color information with an infrared light source off. The image capture method may also include obtaining first luminance image data including luminance information with the infrared light source on. The image capture method may also include generating a first enhanced image based on the first color image data and the first luminance image data.
(FR)
La présente invention concerne des systèmes et des procédés de capture d'image. Le procédé de capture d'image peut consister à obtenir des premières données d'image couleur comprenant des informations de couleur, une source de lumière infrarouge étant éteinte. Le procédé de capture d'image peut également consister à obtenir des premières données d'image de luminance comprenant des informations de luminance, la source de lumière infrarouge étant allumée. Le procédé de capture d'image peut également consister à générer une première image améliorée sur la base des premières données d'image couleur et des premières données d'image de luminance.
