<p>A display monitor (7) may be pivoted into either landscape (8) or portrait (9) orientation. The orientation (8,9) of the display monitor is sensed, and the video data sent to the monitor is translated, as necessary, to maintain the displayed image unrotated regardless of the orientation of the display monitor. This translation is performed, in the case of display data represented in a bit map, by altering the addresses in memory of the data for each pixel to be displayed. The circuitry for producing the displayed images is not altered by rotation of the display monitor (7). <IMAGE></p> |
