    Abstract: Spacers for separating a first lens element from a second lens element, lens modules including such spacers and digital cameras including such lens modules. A spacer may comprising along its perimeter at least one contact section being in contact with the first lens element and the second lens element and at least one non-contact section being separated from the first lens element. The at least one non-contact section comprises an internal inclined surface having designed to reduce or mitigate stray light.

    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: Systems comprising a display having a first pixel array and a gap in the first pixel array in which at least some pixels of the first pixel array are missing, a device such as a camera, a light emitting device or a light receiving device, and a second pixel array. The systems are operable in a first operation mode in which the camera or light emitting device are operative to, respectively, capture images or emit light while the second pixel array is not operative to display information, and in a second operation mode in which the camera or light emitting device are not operative to, respectively, capture images or emit light while the second pixel array is operative to display the second array pixel information in the gap in the first pixel array. Systems are also operable in a third operation mode in which in which the camera or light emitting device are operative to, respectively, capture images or emit light while the second pixel array is operative to display information.

    Abstract: A zoom camera comprising an optical path folding element (OPFE) for folding the light from a first optical path to a second optical path, a first lens having a first optical axis and a first effective focal length EFLL1, the first optical axis being along the second optical path, a collimating lens having a second optical axis, and an image sensor located on the second optical path, wherein the collimating lens is movable between at least a first state and a second state, wherein in the first state the collimating lens is positioned in the second optical path between the OPFE and the first lens such that light entering the first lens arrives only from the image side of the collimating lens, and wherein in the second state the collimating lens is positioned outside the first optical path such that light entering the first lens does not arrive from the image side of the collimating lens.
