  • Patent number: 10820029
    Abstract: A method and apparatus for alerting groups of user devices to similar video content of interest based on role. The method includes providing a first video to groups of user devices, each having an associated user role, receiving viewing metrics indicative of levels of viewing interest for the first video from a first group of user devices associated with a particular user role, and when a level of viewing interest is above a predetermined threshold, classifying one or more corresponding first video frames of the first video as frames of interest. The method further includes receiving a second video, determining, using the frames of interest, that video content of the second video is of interest to a second group of user devices having the particular user role, and providing an alert to the second group of user devices.

  • Patent number: 9028159
    Abstract: A camera module with a lens barrel containing a lens, and a lens carrier that slidably receives the lens barrel. Each of the exterior surface of the lens barrel and the interior surface of the lens carrier include a seating surface formed thereon. One of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of protrusions for controlling the relative position of the lens barrel and the lens carrier. The other of the exterior surface of the lens barrel and the interior surface of the lens carrier include a plurality of channels that are sized and arranged so as to slidably receive the protrusions to allow for the lens barrel to be slid into the lens carrier. The channels also each include a transverse section to allow the lens barrel to be pivoted about an optical axis of the lens barrel.

  • Patent number: 8982267
    Abstract: A camera module including a particle trap. The particle trap may be disposed in the camera module and may be operable to prevent particles from obstructing an optical path defined between a lens assembly and an image sensor. The particle trap may include a particle getter to retain particles in contact with the particle trap. The camera module may be operative to move the lens assembly so as to provide focus on the image sensor for objects at various distances from the camera module. The movement of the lens assembly may be a source of particles retained by the particle trap.

  • Patent number: 8953088
    Abstract: A camera module including an image sensor and a circuit substrate that are each attached to a bottom surface of a glass substrate. The image sensor is positioned between the circuit substrate and the glass substrate. This arrangement allows passive components normally associated with the image sensor to be mounted to a top surface of the glass substrate rather than to the image sensor, thus reducing the necessary size of the top surface of the image sensor, which in turn can reduce the overall size of the image sensor. A lens assembly, including a housing and a lens, is attached to the circuit substrate to position the image sensor and the glass substrate within a cavity provided in the housing.

  • Patent number: 8891002
    Abstract: A camera module having a flash that is provided therein. The flash may be an LED light source. The LED may come in a package that is generally rectangular, with the exception that one corner is flattened. The camera module includes a housing that receives the light source, an image sensor, and a lens. The housing includes mating features that receive the LED package, those features including a flattened corner so that the LED package can only be received within the housing when it is properly oriented. The housing also includes electrical terminals for connection to the LED that include springs. When the LED package is properly oriented and received within the housing, contact pads on the LED package and the electrical terminals on the housing are pressed together against the resilient force of the spring.

  • Patent number: 8858100
    Abstract: A camera module includes a lens system, an image sensor, and an actuator. The actuator is fixed relative to the image sensor, and the actuator moves the lens system relative to the image sensor to achieve focus. Components that move relative to each other result in gaps or spaces between the components, an in particular there is a gap between the lens system and the actuator. Such a gap provides a traveling path for foreign material, or particulates, to enter the camera module and reach the image sensor, or other intermediate optical components between the lens system and the image sensor. A camera contamination reduction apparatus is implemented as a protective membrane that prevents foreign material from reaching the internal optical components through the traveling path.

  • Patent number: 8797453
    Abstract: A camera module having a liquid crystal shutter that controls the time period during which the image sensor is exposed to light directed into the camera module. The shutter is located within the camera module housing, which may include EMI shielding and may include a lens actuator for moving a movable lens group. The shutter may be located before or after the movable lens group and before or after a fixed lens group that may also be included. The camera module may also include an IR filter for reducing the amount of IR light that reaches the image sensor.

  • Publication number: 20120293666
    Abstract: A multi-directional SFR measurement system includes a rotatable test fixture located within an enclosure. Mounted on the test fixture is a test key for holding a camera module under test, a collimating lens, and a target/light source panel that provides a visible target for imaging by the camera module. A controller box located outside of the enclosure allows an operator to command the system to rotate the test fixture to a desired angle and capture an image of the target with the camera module under test. The system also includes an angle indicator to indicate the rotational angle of the test fixture and an air pressure controller/indicator to control and indicate the air pressure of the system used for positioning the collimating lens relative to the test fixture.
