| Summary: | The invention relates to image devices in general. More particularly, the invention relates to a method and apparatus for minimizing burn lines on a cathode ray tube (CRT) display used in an image display device such as a television.
A method and apparatus for displaying a video signal is described. A video signal is received representing an image having a first aspect ratio, with the image having a top and bottom edge. An edge modification signal is generated. The image is displayed on a display having a second aspect ratio with the top and bottom edge modified in accordance with the edge modification signal. Accordingly, burn lines are minimized through use of the edge modification signal to reduce brightness levels at the top and bottom edge of the image. |
