Title (EN) METHOD AND APPARATUS FOR CALCULATING A FOCUS METRIC
(FR) PROCÉDÉ ET APPAREIL POUR CALCULER UNE MESURE DE FOCALISATION
Abstract: front page image
(EN)A method (200) comprises receiving (202) a focusing image and shifting (204) the focusing image to obtain a shifted focusing image. In the method (200), a focus metric of the focusing image is calculated (206) from the focusing image and the shifted focusing image, where the focus metric is configured for use as a factor in making an automatic focus adjustment determination. An automatic focusing apparatus (100) includes a controller (108) configured to implement the method (200).
(FR)Un procédé (200) comprend la réception (202) d'une image de focalisation et un déplacement (204) de l'image de focalisation pour obtenir une image de focalisation déplacée. Dans le procédé (200), une mesure de focalisation de l'image de focalisation est calculée (206) sur la base de l'image de focalisation et de l'image de focalisation déplacée, la mesure de focalisation étant faite pour servir de facteur de détermination de mise au point automatique. Un appareil de focalisation automatique (100) comprend un contrôleur (108) conçu pour mettre en œuvre le procédé (200).
