(FR) MODULE DE CAMÉRA ET SON PROCÉDÉ DE CORRECTION D'OMBRAGE D'OBJECTIF
Abstract
(EN)
Disclosed is a camera module, the module including a memory unit having a DFOV table for storing a DFOV depending on a focal length and a lens shading correction table for storing a lens shading correction function depending on a DFOV value, an image pick-up unit for measuring a focal length using an auto focusing method and acquiring an image, and an image-data correction unit for receiving image data and a focal length from the image pick-up unit, obtaining a DFOV value, selecting a lens shading correction function depending on the obtained DFOV value, and applying the selected lens shading correction function to the image data to perform lens shading correction.
(FR)
La présente invention concerne un module de caméra. Ledit module comprend : une unité de mémoire ayant une table de DFOV servant à mémoriser un DFOV en fonction d'une longueur focale et une table de correction d'ombrage d'objectif servant à mémoriser une fonction de correction d'ombrage d'objectif en fonction d'une valeur du DFOV; une unité de capture d'image servant à mesurer une longueur focale à l'aide d'un procédé de mise au point automatique et à acquérir une image; et une unité de correction de données d'image servant à recevoir des données d'image et une longueur focale de l'unité de capture d'image, à obtenir une valeur de DFOV, à sélectionner une fonction de correction d'ombrage d'objectif en fonction de la valeur du DFOV obtenue et à appliquer la fonction de correction d'ombrage d'objectif sélectionnée aux données d'image afin d'effectuer la correction d'ombrage d'objectif.
