Abstract:
Folded cameras and dual folded-upright cameras that reduce a mobile electronic device and specifically a smartphone bump footprint and height. In some examples, the bump footprint is reduced by reducing the height of a back focal plane section of the folded camera. In some examples, the bump footprint is reduced by reducing the height of a back focal plane section and a lens subsection of the folded camera.
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:
Folded camera modules in which the camera module height is determined by a folded lens module diameter and by the lens module movement in a direction perpendicular to the lens optical axis, and dual-aperture cameras including such folded camera modules. A folded camera module includes OIS and AF actuators having dimensions smaller than the camera module height and therefore not adding to the camera module height.
Abstract:
Zoom digital cameras comprising a Wide sub-camera and a folded fixed Tele sub-camera. The folded Tele sub-camera may be auto-focused by moving either its lens or a reflecting element inserted in an optical path between its lens and a respective image sensor. The folded Tele sub-camera is configured to have a low profile to enable its integration within a portable electronic device.
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 camera comprising a Wide camera with a respective Wide lens and a Tele camera with a respective Tele lens, the Wide and Tele cameras mounted directly on a single printed circuit board, wherein the WTide and Tele lenses have respective effective focal lengths EFL W and EFL T and respective total track lengths TTL W and TTL T and wherein TTL W /EFL W > 1.1 and TTL T /EFL T ZF , where EFL ZF is a zoom-factor dependent effective focal length.
Abstract:
A multi-aperture imaging system comprising a first camera with a first sensor that captures a first image and a second camera with a second sensor that captures a second image, the two cameras having either identical or different FOVs. The first sensor may have a standard color filter array (CFA) covering one sensor section and a non-standard color CFA covering another. The second sensor may have either Clear or standard CFA covered sections. Either image may be chosen to be a primary or an auxiliary image, based on a zoom factor. An output image with a point of view determined by the primary image is obtained by registering the auxiliary image to the primary image.
Abstract:
Electromagnetic actuators (600) for digital cameras, in particular miniature cell- phone and tablet cameras, include an electromagnet with a first elongated ferromagnetic member (616) surrounded coaxially in part by a conductive coil along a first longitudinal axis, and a elongated second ferromagnetic member (618) with a second longitudinal axis. The first and second ferromagnetic members (616, 618) have respective first and second operative surfaces (614, 620) 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 (616, 620) 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.
