Verfahren zur Kompensation geometrischer Bildfehler bei Videobildern sowie eine Vorrichtung zur Durchführung des Verfahrens

摘要

A device for displaying video images on a projection area on which the display is slanted contains a source (10) whose intensity can be modulated for emitting an essentially parallel light beam for a sequential illumination of video image pixels. The invention also contains a deflecting device (11, 12) for line and image rasterization of the light beam and a control device (17) which controls the intensity modulation for the light beam and its deflection (11, 12) according to a function which is determined by a calculated equalization of the image in relation to the slanting.
