Title
(EN) METHOD AND DEVICE FOR RECOVERING IMAGE PASSING THROUGH DISPLAY
(FR) PROCÉDÉ ET DISPOSITIF DE RÉCUPÉRATION D'IMAGE PASSANT PAR UN DISPOSITIF D'AFFICHAGE
Abstract
(EN)
A method for recovering an image passing through a display (2) and taken by an image sensor (6) disposed on a rear side of the display (2), the method includes acquiring the image taken by the image sensor (6), obtaining a plurality of point spread functions corresponding one-to-one to a plurality of dots (D) arranged in a predetermined pattern on a calibration chart (CC), and performing a de-convolution of the image based on the plurality of point spread functions to recover the image.
(FR)
L'invention concerne un procédé de récupération d'une image passant par un dispositif d'affichage (2) et prise par un capteur d'image (6) disposé sur un côté arrière du dispositif d'affichage (2), le procédé consistant à acquérir l'image prise par le capteur d'image (6), obtenir une pluralité de fonctions d'étalement ponctuel correspondant de façon bi-univoque à une pluralité de points (D) agencés selon une configuration prédéterminée sur un graphique d'étalonnage (CC), et effectuer une déconvolution de l'image sur la base de la pluralité de fonctions d'étalement ponctuel pour récupérer l'image.
