Shortening one's sight, a stereoscopic image can also be seen when he/she is watching a pair of pictures (a little different but interrelated with each other) directly. Such a way for watching stereoscopic pictures is better in many aspects than that of stretching sight. This method can be applied to stereoscopic photographs, stereo-movies and stereoscopic TVs, etc. An `off-axis telescope' designed may be used by those who can hardly shorten or stretch his/her sight directly at any position in an empty space for watching stereoscopic pictures.
