how to improve your resolution

How do you improve resolution on a low-end camera?

The attached photographs show exceptional resolution versus poor resolution. As you can see, the greater the temperature differential the better the resolution becomes. If you modify your normal scan on your computer program you can improve resolution by spreading the range of the scan. This may or may not provide the information you’re trying to depict to your client.

How do you stitch sequential thermal scans?

Flir as a $2000 program to combine multiple thermal scans. This actually increases the resolution of your low grade camera to that of a high grade camera by combining multiple exposures into one resolution.

I use the panoramic stitch tool provided by my Hewlett-Packard printer software to put together horizontal photographs.
Has anyone come up with a better solution?

$2000 is a little bit steep for a home inspector application.
