Abstract
Conventional scanners used in thermal imagers scan the image along curved lines rather than straight lines, resulting in image curvature in the display. The invention eliminates this by processing the video signal from the scanner to compose an output video signal which represents scanning along straight lines (18) across the image. The output signal is composed of a number of successive portions (A to F) each derived from a different line or lines of the video signal provided by the scanner.
