ABSTRACT:
An apparatus is provided for receiving the inverted video image of a television set and for enlarging and projecting this image onto a suitable display surface. An adjustable concave mirror, located at a distance from the television set which is dependent upon the size of the enlarged image which is desired, is enclosed in a housing which shields the projected image from being washed out. The housing has a non-reflecting black matte interior finish and an opening through which the image is projected towards the display surface.
