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 LED's (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-LED's (198) is superimposed at the desired location of the visible image provided by the scene-LED's (62').
Un dispositif à imagerie thermique (10) comprend un affichage (62) par diodes électroluminescentes permettant une reproduction d'une scène visualisée. L'affichage (62) par diodes électroluminescentes comprend également un ensemble de diodes (198) capables de former des symboles se superposant sur l'image de la scène visualisée. Un circuit de commande (214) de l'affichage vidéo et un circuit de commande (202) de l'affichage des symboles fonctionnent de manière séquencée pour que le motif du réticule ou les symboles affichés par l'ensemble de diodes (198) se superpose en un endroit souhaité sur l'image visible fournie par les diodes (62') représentant la scène.
