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 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.
