SYSTEM FOR PRODUCING ENHANCED THERMAL IMAGES
First Claim
1. An imaging device, comprising:
- a first sensor operative to receive first sensor input in a first wavelength band from a first sensor imaging field and to generate a corresponding first sensor output signal;
a second sensor operative to receive second sensor input in a second wavelength band from a second sensor imaging field and to generate a corresponding second sensor output signal, the second sensor imaging field containing and being larger in extent than the first sensor imaging field, the first and second sensor imaging fields being of known spatial and temporal registration with respect to each other; and
image processing circuitry operative to;
(1) receive the first and second sensor output signals in a first time slot when a first scene of interest is viewed,(2) receive the first and second sensor output signals in a second time slot when a second scene of interest is viewed, wherein the second sensor imaging field in the first time slot has an overlapping region with the second sensor imaging field in the second time slot; and
(3) analyze the second sensor output signals from the first and second time slots to detect motion and to map the first sensor output signals into a two-dimensional image.

Abstract
An imaging device has a thermal sensor to remotely measure respective temperatures of regions within an imaging field and to generate temperature information signals. A motion tracking system tracks motion of the thermal sensor and generates position information signals representing positions of the thermal sensor during the temperature measurements. An image construction processor uses the position and temperature information signals to generate a two-dimensional image representative of the imaging field including respective temperature indications at different locations within the two-dimensional image, and stores the two-dimensional image within a memory. The two-dimensional image may be used as an output image for display to a user.
