    Abstract: Folded digital cameras comprising a lens system with a lens and an image sensor, the lens having N≥6 lens elements Li, an effective focal length (EFL) and a total track length (TTL), wherein each lens element has a respective focal length fi and wherein a first lens element L1 faces an object side, and an optical path folding element (OPFE) for providing a folded optical path between an object and the lens. In some embodiments, the lens system has a focusing range that covers object-lens distances from infinity to a minimal object distance (MIOD), wherein MIOD/EFL is smaller than 20 or even 7. In some embodiments, the ratio of a maximal chief ray angle to a field of view of the folded camera Max CRA/FOV is smaller than 0.25 or even 0.15 when the camera is focused at infinity.

    Abstract: Systems and methods for eliminating or mitigating T-effects on Hall sensors. A system may comprise a magnet-coil arrangement for providing a relative movement therebetween to obtain a relative position, a Hall sensor for sensing the relative movement, a temperature sensor located in proximity of the Hall sensor for providing temperature sensing, and a controller having two or more channels coupled to Hall sensor and to the temperature sensor and configured to control the relative movement and to provide, based on the temperature sensing, a temperature correction input to the Hall sensor for compensating a temperature effect on the Hall sensor sensing.

    Abstract: Actuators for providing an extended two-degree of freedom rotation range to an optical path folding element (OPFE) such as a prism or mirror in mobile devices such as smartphones, comprising a yaw sub-assembly having a yaw rotation axis, a pitch sub-assembly carrying the OPFE, the pitch sub-assembly including a pivot rotation mechanism and having a pitch rotation axis; and a stationary sub-assembly, wherein the actuator is operative to rotate the OPFE in two rotation directions, a first rotation for yaw around the yaw rotation axis and a second rotation for pitch around the pitch rotation axis, and wherein the rotation for pitch includes rotation using the pivot rotation mechanism.

    Abstract: Methods for stereo calibration of a dual-camera that includes a first camera and a second camera and system for performing such methods. In some embodiments, a method comprises obtaining optimized extrinsic and intrinsic parameters using initial intrinsic parameters and, optionally, initial extrinsic parameters of the cameras, estimating an infinity offset e using the optimized extrinsic and extrinsic parameters, and estimating a scaling factor s using the optimized extrinsic and extrinsic parameters and infinity offset parameter e, wherein the optimized extrinsic and extrinsic parameters, infinity offset e and scaling factor s are used together to provide stereo calibration that leads to improved depth estimation.
