Title (EN) DYNAMIC RANGE EXTENSION BY COMBINING DIFFERENTLY EXPOSED HAND-HELD DEVICE-ACQUIRED IMAGES
(FR) EXTENSION DE PLAGE DYNAMIQUE PAR COMBINAISON D'IMAGES ACQUISES PAR DES DISPOSITIFS TENUS À LA MAIN EXPOSÉS DIFFÉREMMENT
Abstract: front page image
(EN)Two or more digital images of a same scene are captured with different exposure levels. Image pairs are generated that have a same exposure level from the image data of differently exposed images by adjusting the exposure of at least one of the pair of images. A ghosting map is generated based on differences between the pair of images adjusted to the same exposure. A blurred ghosting map is generated and alpha blending is performed.
(FR)Selon l'invention, deux images numériques ou plus d'une même scène sont capturées à des niveaux d'exposition différents. Des paires d'images ayant le même niveau d'exposition sont générées à partir des données d'image des images exposées différemment en ajustant l'exposition d'au moins une des deux images. Une carte fantôme est générée à partir des différences entre les deux images ajustées à la même exposition. Une carte fantôme floutée est générée et un mélange alpha est effectué.
