  • Patent number: 11152528
    Abstract: An apparatus includes at least one detector configured to receive return light from an object within a detector field of view the light generated by a light source. The detector includes first and second photosensitive regions configured to receive the return light from the light source. At least one non-photosensitive region is included, and the first and second photosensitive regions are separated by the at least one non-photosensitive region. The at least one non-photosensitive region is associated with one of the first or second photosensitive regions.
    Type: Grant

  • Patent number: 10878117
    Abstract: An electronic device includes a time-of-flight sensor configured to sense a distance between the electronic device and at least one object proximate the electronic device. Processing circuitry is coupled to the time-of-flight sensor and controls access to the electronic device based on the sensed distance. The electronic device may include a digital camera that the processing circuitry controls to perform facial or iris recognition utilizing the sensed distance from the time-of-flight sensor.

  • Patent number: 10839537
    Abstract: A camera module with a fixed near field focus is configured to capture a single image. That single image is segmented by an image divider a number of regions. A focus metric determiner then determines a focus metric for each of the regions. A depth map generator maps the focus metric into a depth value for each of the regions and combines the depth values to generate a depth map.

  • Patent number: 10461858
    Abstract: An apparatus has a pixel array arrangement having a number of photosensitive detectors. Processing circuitry is configured to process data captured by at least one pixel of the array to provide image information and detect data on an encoded pulsed light signal. In a specific embodiment, data is captured at a vehicle. Information for the vehicle is determined based on the encoded pulsed light signal.

  • Publication number: 20190213348
    Abstract: An electronic device includes a time-of-flight sensor configured to sense a distance between the electronic device and at least one object proximate the electronic device. Processing circuitry is coupled to the time-of-flight sensor and controls access to the electronic device based on the sensed distance. The electronic device may include a digital camera that the processing circuitry controls to perform facial or iris recognition utilizing the sensed distance from the time-of-flight sensor.

  • Patent number: 9420163
    Abstract: An autofocus method determines that a ranging device of a digital camera has failed in an attempt to provide a distance estimation. The ranging device provides one or more parameters indicating conditions related to the failure of the ranging device to provide the distance estimation. An autofocus sequence based on the one or more parameters is then performed.
