Abstract
Logos may be present in images transmitted by television stations. These logos are often present in the corners (102, 104) of an image (100) 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 (102, 104) of the image (100) and reducing their intensity to the average display load.
Claims10
A system for displaying an image, said system comprising:
- a selection means for selecting an area within the image;
- and
- reduction means for reducing a light intensity of the image,
- characterized in that the system further comprises:
- a motion detector for detecting motion and a stationary part within the image;
- and
- wherein the reduction means reduces the light intensity of the stationary part within the area if motion has also been detected within the area.
A method of displaying an image, wherein the method comprises the steps:
- selecting an area within the image;
- and
- reducing a light intensity of the image,
- characterized in that the method further comprises the step
- detecting motion in a stationary part within the image, and
- wherein the reduction step is performed for the stationary part if motion is also detected within the area.
