Abstract

PURPOSE: To obviate the influence in stereoscopic vision even if the viewer's position deviates by detecting the position in the horizontal direction of incident light to the viewer's eyes and aligning the central axis of the incident light nearly to the viewer's eyes by the detection output thereof.
CONSTITUTION: A detector 12 is mounted near one of the eyes of a viewer 3, e.g., his left eye 4L. Where the central axis of the light through a slide 6L and projection lens 7L and the left eye 4L align, the light enters the central photo detector 13d of the detector 12 and a servo motor 9 is held static. Here, when the viewer moves right, the light enters from the photo detector leftward from the center of the detector 12, e.g., 13f. This is discriminated in a position discrimination circuit 17 which then supplies the discrimination signal for causing the support 8 of slids 6R, 6L to move by the specified amount in the arrow 20 direction to a drive circuit 18. Such feedback controlling enables always good stereoscopic vision despite the movement of the viewer 3.
