ABSTRACT:
A thermal imaging device (10) includes a light emitting diode (LED) display (62) providing an image replicating a viewed scene. The LED display (62) also includes an array of symbology LEDs (198) providing symbology superimposed on the image of the viewed scene. A video driver circuit (214) and a symbology driver circuit (202) are time-sequenced so that a reticle pattern or symbology provided by the symbology-LEDs (198) is superimposed at the desired location of the visible image provided by the scene-LEDs (62').
