ABSTRACT:
Changes in characteristics of an image are monitored at a predetermined position or zone (12, 13) of the image. The image is corrected to allow for changes in the monitored position or zone (12, 13). This is done with reference to observed deviation in coordinates of reference points (9-11) of the image. In a preferred embodiment, successive thermographic images are obtained of electronic equipment, such as a printed circuit board, and the image as displayed on a VDU screen (4) is scanned at a predetermined point (12) or along a predetermined line (13) to monitor temperature-dependent color characteristics of the image, whereby the development of hotspots can be monitored. Changes in the coordinates of landmark positions (9-11) on the image are noted and are used to correct the positions of successive images on the screen so that the monitored point (12) or line (13) is always in the same position. This correction is achieved by transformation of data using spread sheet software.
