Devices disclosed herein feature a Wide camera with a Wide field of view (FOV.sub.w), a folded Tele camera with a Tele field of view (FOV.sub.T) smaller than the FOV.sub.w and including an optical path folding element (OPFE). The device may be configured to rotate the OPFE to thereby shift FOV.sub.T relative to FOV.sub.w in response to recognition of an object or subject of interest detected in FOV.sub.w or FOV.sub.T. The device can have high resolution in this overlapping FOV either by fusing the Wide and Tele images or by capturing and saving the Tele image.

This document describes a mirror-based microelectromechanical system (MEMS) for optical image stabilization in image-capture systems. The mirror-based MEMS includes a MEMS platform that can rotate about a pitch axis and/or a yaw axis. MEMS rotors drive rotational motion of the MEMS platform. One or more piezo films, flexibly connected to the stationary platform, extend over the MEMS rotors. The piezo films have a resistance value that varies when the piezo films are deformed by the MEMS rotors. The piezo films form a bridge circuit across the MEMS platform, which produces an output voltage that varies with the resistance values. A MEMS mirror, coupled to the MEMS platform, reflects light rays to an image sensor. A microcontroller receives pitch and yaw information from the image sensor. The microcontroller accesses the output voltage and determines how much to move the MEMS platform to compensate for the pitch and yaw of the camera.

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.sub.W and FOV.sub.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.sub.T relative to FOV.sub.W. In some embodiments, a rectangular FOV.sub.T is orthogonal to a rectangular FOV.sub.W. When included in a host device having a user interface that displays FOV.sub.T within FOV.sub.W, the user interface may be used to position FOV.sub.T relative to FOV.sub.W, scan FOV.sub.T across FOV.sub.W and acquire, store and display separate Wide and Tele images, composite Wide plus Tele images and stitched Tele images. The positioning of FOV.sub.T within FOV.sub.W, can be done automatically (autonomously) by continuously tracking an object of interest.
