Method and apparatus for monitoring the thermal characteristics of an image

A method and apparatus for automatically identifying and tracking the hottest spot in an infrared scene captured and displayed by an infrared camera system. In an Autospot Mode of the present invention, a cursor is automatically positioned on the display device over the hottest spot in the infrared scene image captured by the camera. The temperature at this location is also automatically displayed. The location of the cursor, and the temperature of the scene at this location, are automatically updated for successive frames of data captured and displayed by the infrared camera system. In a Delta Mode of the present invention, the difference in temperature between two points in a thermal image, designated by an operator using first and second cursors, is calculated and displayed.
