PURPOSE:To display a stereoscopic image being suitable for a moving observer without increasing a device scale by providing a projector moving device for moving a pair of projectors in accordance with the observer's position. CONSTITUTION:In accordance with each observer 101-104, pairs of projectors 91-94 for projecting a video light are provided on a lenticular lens seat 81 side, and each pair of projectors 91-94 is provided with two sets of projectors in order to emit a video light for the left eye and the right eye. In such a state, a position detecting device 51 detects a position of each observer 101-104 at any time. Data PS of a detected position is given to an arithmetic unit, in which a position of each projector 91-94 is determined by an arithmetic processing. That is, as for the position detection of each observer 101-104 by the position detecting device 51, a method for using a three-dimensional magnetic sensor, a method by an image processing for utilizing a feature point of a face, a method for measuring by using two sets of distance detection PSDs using infrared rays, etc., are used. |
