Description

Stereoscopic images are no longer judged as true to life when the size of the display screen is insufficient. Human beings reproduced in reduced size appear as if they were animated puppets (puppet theater effect). This paper describes a subjective evaluation experiment carried out to clarify under which input-output conditions of stereoscopic images this effect is significant. Results show that the puppet theater effect is relaxed when the geometric perspective and the stereoscopic depth of the displayed scenery are matched to natural viewing depth conditions. On the other hand, disparity settings required to establish correct depth reproduction generally caused annoying side effects (e.g increased eye-strain). It is concluded that this disparity correction should only be applied for short distance shots watched at near viewing distances, e.g., in conditions typical of video phone applications.
