PROBLEM TO BE SOLVED: To provide a display method for a stereoscopic video which makes it easy for an observer to set the eyes focus to the convergence angle and recognize the spatial effect when observing the stereoscopic video by providing a marker body in or nearby the visual field of observation of the stereoscopic video and displaying the stereoscopic video. SOLUTION: When the observer observes the stereoscopic video from the front in the center of a screen, the base part side of the horizontal part 2A of the mark part 2 is in the observation visual field 3 of the observer for the stereoscopic video, but the tip end side and vertical part 2B of the horizontal part 2A are outside the observation visual field 3. Through a display device like this, the observer when observing the stereoscopic video recognizes the mark part 2 projecting forward form the display screen 1a at the same time with the stereoscopic video. Consequently, the eye of the observer has its convergence angle directed to video projecting form the display screen and is put in focus on the part of the mark part 2 projecting almost as much as the projection position of the projecting video. Therefore, the eye of the observer tends to have the convergence angle and focus nearly matched, and the spatial effect of the projecting video is easily be felt. |
