Abstract

A system for detecting and automatically correcting X-Y errors in displayed image data. In a specific implementation, the invention (6, 10) includes a display driver (12, 14, 16, 4) for commanding the display (2) to display a picture element of an image at a predetermined position on a display screen thereof. The actual position of the displayed picture element is detected (6) and used to calculate a set of correction factors which are used in real time to correct the positioning of picture elements of actual image data (20, 24, 5).
