Further embodiments can involve the imaging device 6 processing the image 88 and the image 90 to generate a composite image representing intensities and wavelengths of both the infrared radiation depicted by the image 88 and the visible radiation depicted by the image 90. For example, the composite image can take the form of a hybrid thermal/visible light image where each pixel of the composite image represents a weighted average of the corresponding pixel of the image 88 and the corresponding pixel of the image 90. A user can operate the user interface of the imaging device to display the composite image with varying “opacity” settings. For example, a 0% opacity setting would render the composite image equivalent to the (e.g., visible light) image 90, a 100% opacity setting would render the composite image equivalent to the (e.g., thermal) image 88, and a 50% opacity setting would cause each pixel of the composite image to be the (unweighted) average of the corresponding pixels of the images 88 and 90.

In another embodiment, the composite image can take a “picture-in-picture” form. Referring to FIG. 14 as an example, the composite image 94 includes a portion 95 of the image 88 and a portion 96 of the image 90. In this context, the portion 96 of the image 90 surrounds the portion 95 of the image 88. Additionally, the portion 95 of the image 88 is aligned with the portion 96 of the image 90 such that the optical axis 61 is represented by a common pixel 97 of the composite image.

Referring to FIG. 8, the method 800 can be performed by an imaging device, such as the imaging device 6.
