  • Patent number: 10244190
    Abstract: Techniques using small form factor infrared imaging modules are disclosed. An imaging system may include visible spectrum imaging modules, infrared imaging modules, illumination 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. 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.

  • 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.

  • Publication number: 20180205894
    Abstract: Various embodiments of the present disclosure may include an imaging system that allows for the transfer of high dynamic range (HDR) radiometric thermal images over a low bitrate interface. The image system may capture HDR images and output the HDR images over a communications interface to be processed. The HDR images may be converted to low dynamic range (LDR) images by a transfer function in order to be sent over the low bitrate interface. An inverse transfer function may also be sent along with the LDR image. Once the LDR image has been sent over the low bitrate interface, the LDR image may be converted to a reconstructed image using the inverse transfer function.
