Abstract: A dual-aperture zoom digital camera operable in both still and video modes. The camera includes Wide and Tele imaging sections with respective lens/sensor combinations and image signal processors and a camera controller operatively coupled to the Wide and Tele imaging sections. The Wide and Tele imaging sections provide respective image data. The controller is configured to combine in still mode at least some of the Wide and Tele image data to provide a fused output image from a particular point of view, and to provide without fusion continuous zoom video mode output images, each output image having a given output resolution, wherein the video mode output images are provided with a smooth transition when switching between a lower zoom factor (ZF) value and a higher ZF value or vice versa, and wherein at the lower ZF the output resolution is determined by the Wide sensor while at the higher ZF value the output resolution is determined by the Tele sensor.

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.

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

Abstract: A multi-aperture imaging system comprising a first camera with a first sensor that captures a first image and a second camera with a second sensor that captures a second image, the two cameras having either identical or different FOVs. The first sensor may have a standard color filter array (CFA) covering one sensor section and a non-standard color CFA covering another. The second sensor may have either Clear or standard CFA covered sections. Either image may be chosen to be a primary or an auxiliary image, based on a zoom factor. An output image with a point of view determined by the primary image is obtained by registering the auxiliary image to the primary image.

Abstract: Folded digital camera module comprising an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis, an image sensor, and a lens module carrying a lens with a symmetry axis parallel to the second optical axis. The camera module is adapted to perform optical image stabilization (OIS) involving at least one tilt motion of the OPFE tilt around an axis such that the OPFE tilt creates an image Roll movement and a shift movement, the OPFE tilt-created image Roll movement compensating for a folded camera module-induced Roll movement and the shift movement cancelable by a movement of the lens module.
