Abstract

L'invention concerne un capteur d'image. Le capteur d'image comprend un réseau d'unités de pixels, une unité de conversion de gain, et un réseau de filtres. Le réseau d'unités de pixels comprend multiples unités de pixels. L'unité de conversion de gain est utilisée pour convertir des charges photogénérées produites par les unités de pixel en signaux analogiques. Le réseau de filtres est disposé sur le réseau d'unités de pixels. Le réseau de filtres comprend multiples filtres. Des couleurs de filtres d'une même couleur correspondent à multiples unités de pixel, les charges photogénérées produites par certaines unités de pixels des multiples unités de pixels correspondant aux filtres de la même couleur étant accumulées et partageant ensuite une unité de conversion de gain pour délivrer en sortie un premier signal analogique, tandis que les charges photogénérées produites par les autres unités de pixels des multiples unités de pixels correspondant aux filtres de la même couleur étant accumulées et partageant une unité de conversion de gain pour délivrer en sortie un second signal analogique. La sensibilité et le rapport signal sur bruit du capteur d'image sont accrus. L'invention concerne également un terminal comprenant le capteur d'image et un procédé d'imagerie.
