    Abstract: Electromagnetic actuators for digital cameras, in particular miniature cell-phone and tablet cameras, include an electromagnet with a first elongated ferromagnetic member surrounded coaxially in part by a conductive coil along a first longitudinal axis, and a elongated second ferromagnetic member with a second longitudinal axis. The first and second ferromagnetic members have respective first and second operative surfaces and are aligned such that their longitudinal axes are parallel and such that respective operative surfaces overlap each other across a gap. The two members are mechanically coupled to respective frames. A frame hinge connects the frames and enables a relative tilt motion between the ferromagnetic members when current passes through the coil. The tilt motion is convertible into a linear displacement along an optical axis of an optical element coupled to the actuator. Two actuators can be combined into an assembly capable of providing double-axis tilt.

    Abstract translation: 用于数字照相机，特别是微型手机和平板照相机的电磁致动器包括具有第一细长铁磁构件的电磁体，该第一细长铁磁构件部分地沿着第一纵向轴线被导电线圈同轴地包围，并且具有第二纵向轴线的细长的第二铁磁构件 。 第一和第二铁磁构件具有相应的第一和第二操作表面，并且对准，使得它们的纵向轴线平行并且使得相应的操作表面跨越间隙彼此重叠。 两个构件机械地联接到相应的框架。 框架铰链连接框架，并且当电流通过线圈时，能够在铁磁构件之间实现相对的倾斜运动。 倾斜运动可以沿着耦合到致动器的光学元件的光轴转换成线性位移。 两个执行器可以组合成能够提供双轴倾斜的组件。

    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.
