  • Patent number: 7538326
    Abstract: Methods and apparatuses of registering on a camera display separate fields of view of a visible light camera module and an infrared camera module by focusing the IR camera module. The fields of view can be displayed in several display modes including 1) full screen visible, infrared and/or blended, 2) picture-in-a-picture such as partial infrared image in a full screen visible image, and 3) infrared color alarms in visible-light images.

  • Publication number: 20090050806
    Abstract: A visible light (VL) and infrared (IR) combined image camera with a laser pointer. The laser pointer may be used for marking a hot spot on an object or for focusing an IR lens of a camera on an object. The laser pointer may be adjacent to the VL optics and offset from the IR optics. The VL sensor array may be much larger than the IR sensor array and the camera may also display the pixels of IR data with a much larger instantaneous field of view than the VL pixels. The camera may also provide audible alarms where the alarm is emitted with a tone of variable output to indicate the relative level of the alarm.
