  • Publication number: 20180262658
    Abstract: Various embodiments of the present disclosure may include an imaging device configured to determine appropriate conditions for updating non-uniformity correction (NUC) terms. In certain embodiments, the imaging device may determine when the imaging device is likely not in use and update NUC terms during the times when the imaging device is likely not in use. Data from various position sensors such as gyroscopes, accelerometers, global positioning system receivers, and/or other data may be used to determine when the imaging device is likely not in use. Such position sensors may be coupled to the imaging device and/or may be remote from the imaging device. In certain embodiments, while NUC terms are updated, imaging data obtained may be modified with historical data to provide usable data.

  • Patent number: 10051210
    Abstract: Various techniques are provided for binning (e.g., clustering or grouping) two or more infrared sensors of a focal plane array (FPA) to permit configuration of the FPA to various dimensions and/or pixel sizes. For example, according to one or more embodiments, switchable interconnects may be implemented within the FPA, wherein the switchable interconnects comprise a plurality of switches adapted to selectively connect or disconnect infrared sensors of the FPA to/from column lines, row lines, and between each other. The switchable interconnects may also comprise another set of switches adapted to selectively connect adjacent column lines together. By selectively opening and closing appropriate switches of the switchable interconnects, two or more neighboring infrared sensors may be binned together to form a binned detector. Advantageously, the binned detector, along with the array and associated circuitry, may provide increased sensitivity, reduced power consumption, and/or increased frame rate.

  • Patent number: 10033944
    Abstract: Techniques using small form factor infrared imaging modules are disclosed. An imaging system may include visible spectrum imaging modules, infrared imaging modules, and other modules to interface with a user and/or a monitoring system. Visible spectrum imaging modules and infrared imaging modules may be positioned in proximity to a scene that will be monitored while visible spectrum-only images of the scene are either not available or less desirable than infrared images of the scene. Imaging modules may be configured to capture images of the scene at different times. Image analytics and processing may be used to generate combined images with infrared imaging features and increased detail and contrast. Triple fusion processing, including selectable aspects of non-uniformity correction processing, true color processing, and high contrast processing, may be performed on the captured images. Control signals based on the combined images may be presented to a user and/or a monitoring system.
