LICHTVENTILPROJEKTOR ZUR ALTERNATIVEN WIEDERGABE VON FERNSEHSIGNALEN UNTERSCHIEDLICHER BILDSEITENVERHÄLTNISSE.

摘要

The invention relates to a light valve projector for displaying television signals of two different picture width to picture height ratios. The picture width to picture height ratio of the light valve corresponds to the geometric mean of the two picture width to picture height ratios. The projection optics of the light valve projector exhibit a rotatable anamorphotic lens for stretching the picture to be displayed in the horizontal or vertical direction.
