Abstract
(EN)
This degree-of-focus detection device comprises an imaging optical system for taking in subject image light, a pixel array unit in which phase difference detection pixels for obtaining a first image and second image on the basis of light beams that have passed through a first pupil area and second pupil area of the imaging optical system are arranged in a two-dimensional array, and a detection unit for, for each of a plurality of in-focus images photographed at different distances, detecting phase difference detection pixels where the brightness difference between the first image and second image is less than or equal to a prescribed value.
(FR)
La présente invention concerne un dispositif de détection de degré de mise au point qui comprend un système optique d'imagerie permettant de recueillir la lumière de l'image d'un sujet, une unité de réseau de pixels dans laquelle des pixels de détection de différence de phases servant à obtenir une première image et une seconde image sur la base de faisceaux lumineux qui ont traversé une première zone de pupille et une seconde zone de pupille du système optique d'imagerie sont agencés selon un réseau bidimensionnel, et une unité de détection permettant, pour chaque image d'une pluralité d'images nettes photographiées à différentes distances, de détecter des pixels de détection de différence de phases pour lesquels la différence de luminosité entre la première image et la seconde image est inférieure ou égale à une valeur prédéfinie.
