Title (EN) CONTROLLING FLASH UNIT DURING EXPOSURE OF IMAGE SENSOR
(FR) APPAREIL, PROCÉDÉS ET SUPPORTS DE STOCKAGE LISIBLES PAR ORDINATEUR
Abstract:
(EN) An apparatus comprising: a processor configured to control a flash unit in an exposure time period of an image sensor array, to provide a first non-zero light intensity in a first portion of the exposure time period and to provide a second non-zero light intensity, different to the first light intensity, in a second portion of the exposure time period.
(FR) L'invention porte sur un appareil comprenant : un processeur configuré pour commander une unité flash dans une période de temps d'exposition d'un réseau de détecteur d'image, pour fournir une première intensité de lumière non nulle dans une première partie de la période de temps d'exposition et pour fournir une seconde intensité de lumière non nulle, différente de la première intensité de lumière, dans une seconde partie de la période de temps d'exposition.
