Abstract
Logos may be present in images transmitted by television stations. These logos are often present in the corners () of an image () for a long time. They do not move and may comprise saturated colors. This results in burn-in effects in emissive displays because the logos provide the same display load at the same location for a relatively long period of time. The burn-in effect can be prevented by detecting the logos in the corners () of the image () and reducing their intensity to the average display load.
