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: A dual-aperture camera comprising a first camera having a first sensor and a first image signal processor (ISP), the first camera operative to output a first stream of frames, a second camera having a second sensor and a second ISP, the second camera operative to output a second stream of frames, and a synchronization and operation control module configurable to control operation of one camera in a fully operational mode and operation of the other camera in a partially operational mode and to output an output of the fully operational camera as a dual-aperture camera output, whereby the partially operational mode of the other camera reduces a dual-aperture camera the power consumption in comparison with a full operational mode of the other camera.

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.
