    Abstract: Inductance-based sensing in a digital camera in which actuation of at least one electromagnetic (EM) actuator that includes at least one stationary ferromagnetic member associated with a large air gap causes a moving ferromagnetic member mechanically coupled to an optical element to by-pass or bridge the large air gap through at least one smaller air gap. The stationary member includes at least one ferromagnetic core surrounded at least partially by a coil. An inductance value correlated with a position of the optical element may be measured using the same coil as the one used for the actuation. In some embodiments, a single EM actuator includes two coils and the actuator is driven using both coils, while a regular or a mutual inductance is measured. In some camera embodiments that include two opposite EM actuators, one actuator is used to move the optical element while the other actuator is used to measure the inductance value.

    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: Electro-magnetic actuators used to provide a displacement of an optical element such as a lens carrier comprise at least one ferromagnetic frame associated with a large air gap and at least one ferromagnetic member parallel to and separated from an elongated section of a frame by a small air gap. Actuation causes a magnetic circuit that appears in the at least one frame, the at least one member and small air gaps and by-passes or bridges the large air gap. In some embodiments, the resultant magnetic force moves the at least one member and leads to the displacement of an optical element attached thereto. In some embodiments, at least one frame and at least one member are arranged to provide a center hole and are dimensioned to enable insertion of a lens carrier in the hole. In some embodiments, the displacement is for auto-focus. In other embodiments, the displacement is for optical image stabilization.
