  • Patent number: 11966147
    Abstract: Cameras with OIS capable of performing multi zoom super macro photography and handheld electronic devices comprising such cameras. A camera may include a lens comprising N lens elements L1-LN divided into two or more lens groups arranged along a lens optical axis starting with L1 on an object side and ending with LN on an image side, adjacent lens groups separated by a respective air-gap d1 along the lens optical axis; an image sensor with a sensor diagonal SD between 7 and 20 mm separated from lens element LN by an air-gap d2 along the lens optical axis; and an actuator for controlling air-gaps d1 and d2 to switch the camera between M?1 operative pop-out states and a collapsed state and to focus the camera on an object at an object-lens distance of less than 30 cm.

  • Patent number: 11953659
    Abstract: An optical lens assembly includes five lens elements and provides a TTL/EFL<1.0. In an embodiment, the focal length of the first lens element f1<TTL/2, an air gap between first and second lens elements is smaller than half the second lens element thickness, an air gap between the third and fourth lens elements is greater than TTL/5 and an air gap between the fourth and fifth lens elements is smaller than about 1.5 times the fifth lens element thickness. All lens elements may be aspheric.

  • Publication number: 20240077704
    Abstract: A zoom camera comprising an optical path folding element (OPFE) for folding the light from a first optical path to a second optical path, a first lens having a first optical axis and a first effective focal length EFLL1, the first optical axis being along the second optical path, a collimating lens having a second optical axis, and an image sensor located on the second optical path, wherein the collimating lens is movable between at least a first state and a second state, wherein in the first state the collimating lens is positioned in the second optical path between the OPFE and the first lens such that light entering the first lens arrives only from the image side of the collimating lens, and wherein in the second state the collimating lens is positioned outside the first optical path such that light entering the first lens does not arrive from the image side of the collimating lens.

  • Patent number: 11914117
    Abstract: Folded digital cameras comprising a lens system with a lens and an image sensor, the lens having N?6 lens elements Li, an effective focal length (EFL) and a total track length (TTL), wherein each lens element has a respective focal length fi and wherein a first lens element L1 faces an object side, and an optical path folding element (OPFE) for providing a folded optical path between an object and the lens. In some embodiments, the lens system has a focusing range that covers object-lens distances from infinity to a minimal object distance (MIOD), wherein MIOD/EFL is smaller than 20 or even 7. In some embodiments, the ratio of a maximal chief ray angle to a field of view of the folded camera Max CRA/FOV is smaller than 0.25 or even 0.15 when the camera is focused at infinity.

  • Patent number: 10223545
    Abstract: A request is received from a first agent, the request having a filesystem namespace and an operation identifier (ID) identifying one or more operations to be performed within the file system namespace. In response to the request, a security unit is identified based on a first agent ID identifying the first agent. It is determined whether the security unit contains an operation set ID corresponding to the operation ID of the request. It is determined whether the security unit contains information identifying a set of one or more file system management object (FSMOs) associated with the requested filesystem namespace. The one or more operations are allowed to be performed on the one or more FSMOs, in response to determining that the security unit contains information matching the operation ID of the request and the filesystem namespace of the first request.

  • Patent number: 9471807
    Abstract: Exemplary methods include receiving a message from an agent requesting to perform a first set of operations on a first set of storage namespaces mapped to a first set of file system management objects (FSMOs) in the PBBA. The methods include determining whether to allow or deny the first set of operations based on information stored in a plurality of security units, each security unit comprising of an operation set identifier (ID), a set of FSMO IDs, and an agent ID, wherein the agent ID identifies an agent that is allowed to perform a set of operations identified by the operation set ID on a set of FSMOs in the PBBA identified by the set of FSMO IDs, and in response to determining to allow the first set of operations, performing the first set of operations.
