Abstract
A thin film screen of disc form which is semi-transparent is rotated at high speed about its axis at right angles to the projection path of a projected movie or slide picture through an aperture within a main housing for 90.degree. projection through a side aperture by way of an inclined mirror and a close up lens directly into a video camera through its lens system. A second close-up lens is located in front of the transparent screen for focussing the projected picture onto the screen at the focal plane of the close-up lens. A micromotor which is battery operated drives the mylar screen disc at a comparatively higher speed than that of the projected movie picture.
