摘要
An arrangement for displaying video images on a projection surface, in which the display is carried out on the projection surface at an inclination, comprises a source for the emission of a substantially parallel light bundle for a sequential illumination of image points of the video image, which source can be intensity-modulated, a deflection device for scanning the light bundle in two dimensions, and a control device which controls the intensity modulation for the light bundle as well as the deflection of the light bundle in accordance with a function that is obtained through a calculated distortion correction of the image, at least with respect to the inclination. A method for the compensation of geometric image errors in video images is also disclosed.
