Title (EN) CALIBRATION OF HYBRID AUTO FOCUS (AF) IMAGING SYSTEMS
(FR) ÉTALONNAGE DE SYSTÈMES D'IMAGERIE AVEC AUTOFOCUS HYBRIDE (AF)
Abstract:
(EN) Methods and apparatuses for calibration of hybrid auto focus (AF) imaging systems are disclosed. In one aspect, a method is operable by an imaging device including a hybrid auto focus (AF) system comprising a lens. The method may include capturing an image of a scene, determining that the image of the scene is out of focus, and estimating, via a first AF process of the hybrid AF system, an initial lens position at which the image is in focus in response to determining that the image is out of focus; moving the lens to the initial lens position. The method may also include determining, via a second AF process of the hybrid AF system, a final lens position in response to the movement of the lens to the initial lens position and calibrating the first AF processes based on the determined final lens position.
(FR) L'invention concerne des procédés et des appareils d'étalonnage de systèmes d'imagerie avec autofocus hybride (AF). Selon un aspect de l'invention, un procédé peut être utilisé par un dispositif d'imagerie comprenant un système d'autofocus hybride (AF) comprenant un objectif. Le procédé peut consister à : capturer une image d'une scène, déterminer que l'image de la scène est défocalisée et estimer, selon un premier processus AF du système AF hybride, une position d'objectif initiale à laquelle l'image est focalisée, en réponse à la détermination selon laquelle l'image est défocalisée; et déplacer l'objectif à la position d'objectif initiale. Le procédé peut également consister à déterminer, selon un second processus AF du système AF hybride, une position d'objectif finale en réponse au déplacement de l'objectif à la position d'objectif initiale; et étalonner le premier processus AF sur la base de la position d'objectif finale déterminée.
