  • Patent number: 12019224
    Abstract: This document describes systems and techniques directed at an external wide-angle lens for imagers in electronic devices. An imager is disclosed that includes an image sensor and a lens stack, the lens stack including an external wide-angle lens, an internal lens, and four or more intermediate lenses. The imager has a first ratio of a projection at a vertex of the external wide-angle lens divided by a maximum focused dimension of the focal area being less than or equal to 0.15, a second ratio of a total length of the lens stack divided by the maximum focused dimension being less than or equal to 7.0, or a third ratio of a total transmission length of the imager divided by an entrance pupil diameter of the external wide-angle lens being between 1.2 and 2.6.
    Type: Grant

  • Patent number: 11842612
    Abstract: A battery-powered camera includes a system processor configured to operate in a standby mode or a full-power mode. While operating the system processor in the standby mode, the camera detects an event in a field of view of the camera; records, using an image sensor of the camera, a plurality of image frames corresponding to the field of view in which the event was detected; stores in a frame buffer the plurality of image frames; and wakes the system processor from the standby mode. While operating the system processor in the full-power mode, the camera processes the plurality of image frames stored in the frame buffer using the system processor; and provides the processed image frames for streaming.
