Abstract: Methods for obtaining a shallow depth of field effect (DOF) and improved signal-to-noise (SNR) in an image through synthetically increase the camera aperture of a compact camera using at least one actuator included in such a camera for other known purposes, for example for providing optical image stabilization (OIS). The synthetically enlarged camera aperture enables to take a plurality of images at different aperture positions. The plurality of images is processed into an image with shallow DOF and improved SNR.

Abstract: Systems and methods for correcting point of view (POV) aberrations in scanning folded cameras and multi-cameras including such scanning folded cameras. In a Tele folded camera that includes an optical path folding element (OPFE) and an image sensor, the OPFE is tilted in one or two directions to direct the Tele folded camera towards a POV of a scene, a Tele image or a stream of Tele images is captured from the POV, the Tele image having POV aberrations and the POV aberrations are digitally corrected to obtain an aberration-corrected image or stream of images.

Abstract: Systems, imaging devices and methods for creating background blur in camera panning or motion. Using an imaging device with an image sensor, a method may comprise selecting an object to be tracked in a scene, recording an image or an image stream, and aligning the selected object optically and/or digitally to a same position on the image sensor while the selected object moves relative to the imaging device or relative to the scene, thereby creating a blurred image background and/or foreground relative to the selected object and a sense of panning or motion.

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 output, in a zoom-in operation between a lower zoom factor (ZF) value and a higher ZF value, a zoom video output image that includes only Wide image data or only Tele image data, depending on whether a no-switching criterion is fulfilled or not.

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.
