발명의 명칭: (EN) LOCAL TONE MAPPING
(FR) MAPPAGE DE TONALITÉ LOCAL
요약서:
(EN) Systems and methods are disclosed for image signal processing. For example, methods may include receiving an image from an image sensor; applying a filter to the image to obtain a low-frequency component image and a high-frequency component image; determining a first enhanced image based on a weighted sum of the low-frequency component image and the high-frequency component image, where the high-frequency component image is weighted more than the low-frequency component image; determining a second enhanced image based on the first enhanced image and a tone mapping; and storing, displaying, or transmitting an output image based on the second enhanced image.
(FR) La présente invention concerne des systèmes et des procédés de traitement de signaux d'image. Par exemple, des procédés peuvent consister à recevoir une image en provenance d'un capteur d'image; à appliquer un filtre à l'image pour obtenir une image de composante basse fréquence et une image de composante haute fréquence; à déterminer une première image améliorée sur la base d'une somme pondérée de l'image de composante basse fréquence et de l'image de composante haute fréquence, l'image de composante haute fréquence étant davantage pondérée que l'image de composante basse fréquence; à déterminer une seconde image améliorée sur la base de la première image améliorée et d'un mappage de tonalité; et à stocker, à afficher ou à transmettre une image de sortie sur la base de la seconde image améliorée.
