PURPOSE:To easily obtain natural stereoscopic feeling, by superposing two same videos shifting horizontally, observing them by the left eye and the right eye, respectively, and observing the video at a position separated by a distance corresponding to parallax by the left eye and the right eye, respectively. CONSTITUTION:Two pairs of cathode-ray tube devices for television or projecting devices for a projector are prepared, and a first video A and a second video B in which the first video A is shifted by a distance L (for example, several cm) corresponding to the parallax of both eyes horizontally are displayed on the same screen by using two pairs of display devices, and they are observed by the left eye and the right eye, respectively by using polarizing spectacles. Thus, a left eye image and a right eye image are superposed and displayed as video generated by separate display devices, and the deviation of an image corresponding to the parallax of both eyes is performed by an electrical means. In other words, it is realized by shifting the scanning position of a display tube by performing the insertion of a delay line, synchronous position deviation, and a DC offset, etc. In such a way, it is possible to observe a pseudo stereoscopic image with the natural stereoscopic feeling. |
