Indoor picture projecting method

Abstract

Abstract PURPOSE:To visuarize a magnified projected picture on a screen by making the inside of a room bright by polarized light whose polarized face is maintained and projecting a picture having other polarized plane from a liquid crystal TV onto a stereoscopic screen so as to keep a prescribed lightness by a window or a lighting inside the room or the like. CONSTITUTION:A polarization filter 9 having a longitudinal polarized face is provided to a window 4 and a lighting 5 arranged in a room 2 of a house or the like so as to keep a prescribed lightness by projecting a light having a one polarized face to the inside of the room 2. Moreover, a polarized light holding reflecting film 10 is provided to the reflecting face such as a wall face of the room 1 or the surface of ceiling as a stereoscopic screen so that the light transmitted through the filter 9 is reflected while keeping its polarization. Furthermore, a projector 12 of a liquid crystal TV is arranged on a desk 6, the screen 8 is arranged corresponding to the projection lens 18 of the projector 12 and the polarized plate 9' whose polarized direction is at a right angle to an external light is sticked onto the surface of the screen 8 via the reflecting film 10.
