PURPOSE:To enable the visual recognition of the superimposition of a movie to be selected by intention of an individual. CONSTITUTION:An optical system for projecting an image 1, an optical system for projecting superimposition 2 and a polarizing plate 4 arranged on the optical axis of the optical system 2 are provided. Besides, it is available that a polarizing plate 3 having the plane of polarization orthogonal to the polarizing surface of the plate 4 is arranged on the optical axis of the optical system 1. It is also available that an optical system for projecting both of an image and superimposition 6, a half mirror 7 superposing light for projecting an image and light for projecting superimposition, a mirror 8 for reflecting the light for projecting superimposition on the mirror 7 and the polarizing plate 4 are provided. Besides, it is available that the polarizing plate 3 is added to them. |
