Dual-aperture zoom digital camera with automatic adjustable tele field of view
Digital camera comprising an upright Wide camera configured to provide a Wide image with a Wide image resolution and a folded Tele camera configured to provide a Tele image with a Tele image resolution higher than the Wide image resolution, the Wide and Tele cameras having respective Wide and Tele fields of view FOV W and FOV T and respective Wide and Tele image sensors, the digital camera further comprising a rotating OPFE operative to provide a folded optical path between an object or scene and the Tele image sensor, wherein rotation of the OPFE moves FOV T relative to FOV W . In some embodiments, a rectangular FOV T is orthogonal to a rectangular FOV W . When included in a host device having a user interface that displays FOV T within FOV W , the user interface may be used to position FOV T relative to FOV W , scan FOV T across FOV W and acquire, store and display separate Wide and Tele images, composite Wide plus Tele images and stitched Tele images. The positioning of FOV T within FOV W , can be done automatically (autonomously) by continuously tracking an object of interest.
