Digital image processing and display techniques utilizing differential image intensity determinations.

摘要

Techniques of image processing and display particularly adapted for use in thermography. A first heat image is digitized and stored. A second heat image is acquired, digitized and then compared point-by-point with that of the first image. Any differences in intensity between the two images are also stored. The difference data is used to display on a CRT an optical image of the thermal differences between the two images, thus allowing comparison of the heat radiant characteristics of one object with a standard, or such characteristics of an object at different times.
