Abstract:
In a method for projecting an image onto a projection area (10) by at least one first (110) and second (210) beam, in order to create an improved image on the projection area, the deviation of the projection of the first and second beam on the projection area is determined, and the intensity of the first and/or second beam is varied over time according to the previously determined deviations.
