PROJECTOR FOR PROJECTING IMAGES

The control unit of a projector drives modulators for the range of brightness of the image data with a first resolution of NN levels, wherein NN is an integer greater than one. The control unit applies a predefined brightness change to the brightness value in accordance with the image data for the i...

Beschreibung
Zusammenfassung:	The control unit of a projector drives modulators for the range of brightness of the image data with a first resolution of NN levels, wherein NN is an integer greater than one. The control unit applies a predefined brightness change to the brightness value in accordance with the image data for the image point such that a changed brightness value having a second resolution, which is greater than the first resolution, is calculated, and converts the changed brightness value into the increased brightness value such that it has the first resolution and is greater than a notional comparison value having the first resolution that arises if the predefined brightness change is applied to the brightness value in accordance with the image data, with the result that the control unit drives one of the modulators for a pixel to be boosted with the increased brightness value having the first resolution.
