Abstract: Compact folded camera modules having auto-focus (AF) and optical image stabilization (OIS) capabilities and multi-aperture cameras including such modules. In an embodiment, a folded camera module includes an optical path folding element (OPFE) for folding light from a first optical path with a first optical axis to a second optical path with a second optical axis perpendicular to the first optical axis, an image sensor and a lens module carrying a lens with a symmetry axis parallel to the second optical axis. The lens module can be actuated to move in first and second orthogonal directions in a plane perpendicular to the first optical axis, the movement in the first direction being for auto-focus and the movement in the second direction being for OIS. The OPFE can be actuated to tilt for OIS.

Abstract: Actuators for actuating a lens in a folded camera, folded cameras including such actuators and dual-cameras including such folded cameras. The actuators actuate a lens having a lens optical axis for auto-focus (AF) and optical image stabilization (OIS) and comprise a stationary sub-assembly that includes an OIS coil having an OIS coil plane and an AF coil having an AF coil plane, and a lens actuating sub-assembly movable relative to the stationary sub-assembly with a lens holder holding the lens, wherein the OIS coil plane is perpendicular to the AF coil plane and wherein the lens optical axis lies between the OIS coil plane and the AF coil plane. Some actuators have a design using VCM actuation and a reduced height due to top and/or bottom openings in actuator envelopes.

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: 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: Systems and methods for mitigating or preventing eye damage from structured light IR/NIR projector systems. When a SL projector with a multi-light-source array that projects a SL pattern onto an object, a first camera images the light pattern projected on the object and optionally provides camera frames viewed by a user. A multi-light-source array controller is configurable to control separately an on or off status and/or an intensity of each light source in the multi-light-source array, and an algorithm is operative to detect in the first camera frames SL pattern elements projected onto the object, to detect the eyes of the user, to compare a position of each projected SL pattern element with a position of the detected eyes, and to send commands to the multi-light-source array controller to turn off or reduce the intensity of array light sources that are projected or likely to be projected onto the user's eyes.

Abstract: Dual-aperture digital cameras with auto-focus (AF) and related methods for obtaining a focused and, optionally optically stabilized color image of an object or scene. A dual-aperture camera includes a first sub-camera having a first optics bloc and a color image sensor for providing a color image, a second sub-camera having a second optics bloc and a clear image sensor for providing a luminance image, the first and second sub-cameras having substantially the same field of view, an AF mechanism coupled mechanically at least to the first optics bloc, and a camera controller coupled to the AF mechanism and to the two image sensors and configured to control the AF mechanism, to calculate a scaling difference and a sharpness difference between the color and luminance images, the scaling and sharpness differences being due to the AF mechanism, and to process the color and luminance images into a fused color image using the calculated differences.
