Abstract

A video camera which is convertable into a projector includes a detachable view finder having an eye-piece for viewing a scene to be recorded and an opto-electrical converter which converts the scene into an electronic image. A coupling supports the view finder during use as a camera or a light source during use as a projector. A display screen receives the electronic image and converts the electronic image into a visible image. A switch selectively connects the display screen to input terminals during use as a camera and to output terminals during use as a projector. The opto-electronic converter is pivotable away from the display screen when the camera is used as a projector.
