certain criteria a visible light vl image of the scene may be additionally captured via the aforementioned visible light camera module 206 the camera such as via its processor 222 running a programmed algorithm then performs post processing steps 904 aligning and averaging the images during the calculation process the user may experience an hourglass or other icon or image on the display 108 indicating the camera is performing processing steps a live thermal image may not be shown on display 108 during processing in certain circumstances this situation may be undesirable to the user in other embodiments a live thermal image may be available to view on display 108 during processing during processing the user may abort 997 the calculation resulting in the return of live thermal imagery to the display 108 and readying the device for further use 998 if the calculation is not aborted the camera will align and average the ir images resulting 905 in an averaged thermal scene in some embodiments the averaged thermal scene may have a visible light image associated therewith the processing steps of alignment and averaging of an embodiment of the invention are detailed further in fig9 b after a camera has acquired 910 a series of n ir images it selects 911 one of said images to be a reference image in certain embodiments the processor selects the first of the series of acquired images as the reference image in other embodiments other images from the series may be selected the processor 222 next performs an alignment calculation 912 such as those mentioned above to determine how much if any the n.
