1. A non-transitory computer readable medium containing executable instructions causing one or more processors to perform a method of creating an infrared image of a scene that emphasizes the locations of visible edges, the method comprising: receiving visible light (VL) image data associated with a plurality of VL pixels indicative of a VL image of a target scene; receiving infrared (IR) image data associated with a plurality of IR pixels indicative of an IR image of the target scene, each IR pixel having a corresponding one or more VL pixels indicative of the same portion of the target scene; determining which VL pixels correspond to edges in the VL image data and considering such pixels as VL edge pixels; and generating display image data associated with a plurality of display pixels, each display pixel having corresponding VL and IR pixels that correspond to the same portion of the target scene as such display pixel; wherein some of the display pixels include IR image data associated with corresponding IR pixels, and display pixels corresponding to VL edge pixels include a predetermined color that is independent of the received VL and IR image data and do not include IR image data associated with corresponding IR pixels in order to emphasize the location of edges in the display image data.
