Abstract
(EN)
The present invention provides an imaging device capable of speeding up AF and a focusing control method therefor. The present invention is provided with: a focus lens driving unit (16) for driving a focus lens (12); and an image sensor movement driving unit (120) for moving an image sensor (110) along an optical axis (L). A target position of the focus lens (12) for focusing on a subject is set, and the focus lens (12) is moved toward the target position. Before the focus lens (12) reaches the target position, the image sensor (110) is moved and focused. After being focused, the image sensor (110) is moved so as to follow the focus lens (12) to maintain the focusing state.

La présente invention concerne un dispositif d'imagerie permettant d'accélérer la mise au point automatique (AF) et un procédé de commande de mise au point associé. La présente invention comprend : une unité (16) de commande de lentille de mise au point permettant de commander une lentille de mise au point (12) ; et une unité (120) de commande de déplacement de capteur d'image permettant de déplacer un capteur d'image (110) le long d'un axe optique (L). Une position cible de la lentille de mise au point (12) pour la mise au point sur un sujet est définie, et la lentille de mise au point (12) est déplacée vers la position cible. Avant que la lentille de mise au point (12) n'atteigne la position cible, le capteur d'image (110) est déplacé et mis au point. Après sa mise au point, le capteur d'image (110) est déplacé de sorte à suivre la lentille de mise au point (12) pour maintenir l'état de mise au point.
