Title
(EN) OPTICAL DEVICES FOR TILT IN CAMERA SYSTEMS
(FR) DISPOSITIFS OPTIQUES POUR INCLINAISON DANS DES SYSTÈMES DE CAMÉRA
Abstract
(EN) Aspects of the present disclosure generally relate to optical devices and related methods that facilitate tilt in camera systems, such as tilt of a lens. In one example, an optical device includes a lens, an image sensor disposed below the lens, a plurality of magnets disposed about the lens, and a plurality of: (1) vertical coil structures coiled in one or more vertical planes and (2) horizontal coil structures coiled in one or more horizontal planes. When power is applied, the coil structures can generate magnetic fields that, in the presence of the magnets, cause relative movement of the coil structures and associated structures. The plurality of vertical coil structures are configured to horizontally move the lens. The plurality of horizontal coil structures are configured to tilt the lens when differing electrical power is applied to at least two of the plurality of horizontal coil structures.
(FR) Des aspects de la présente divulgation concernent généralement des dispositifs optiques et des procédés associés qui facilitent l'inclinaison dans des systèmes de caméra, tels que l'inclinaison d'une lentille. Dans un exemple, un dispositif optique comprend une lentille, un capteur d'image disposé au-dessous de la lentille, une pluralité d'aimants disposés autour de la lentille et une pluralité de : (1) structures de bobine verticale enroulées dans un ou plusieurs plans verticaux et des (2) structures de bobine horizontale enroulées dans un ou plusieurs plans horizontaux. Lorsqu'une puissance est appliquée, les structures de bobine peuvent générer des champs magnétiques qui, en présence des aimants, provoquent un mouvement relatif des structures de bobine et des structures associées. La pluralité de structures de bobine verticale sont conçues pour déplacer la lentille horizontalement. La pluralité de structures de bobine horizontale sont conçues pour incliner la lentille lorsque la puissance électrique différente est appliquée à au moins deux de la pluralité de structures de bobine horizontale.
