Stereoscopic display device for multiple observers

A stereoscopic display device for multiple observers comprising:

• an optical element configured to restrict a position where each of a first right-eye image visually recognized by a right eye of a first observer, a first left-eye image visually recognized by a left eye of the first observer, a second right-eye image visually recognized by a right eye of a second observer, and a second left-eye image visually recognized by a left eye of the second observer is visually recognizable;
• a display having a display surface including a plurality of pixels arranged in a first direction and a second direction intersecting the first direction and configured to display the first right-eye image, the first left-eye image, the second right-eye image, and the second left-eye image on the display surface;
• and
• a display controller operable to detect a relative position between the eyes of the first observer and the eyes of the second observer, the display controller further being configured to control the display so that at least one of a first right-eye viewpoint region where the first right-eye image is visually recognizable and a first left-eye viewpoint region where the first left-eye image is visually recognizable is wider than a distance between the right eye and the left eye of the first observer, at least one of a second right-eye viewpoint region where the second right-eye image is visually recognizable and a second left-eye viewpoint region where the second left-eye image is visually recognizable is wider than a distance between the right eye and the left eye of the second observer, the first right-eye image is displayed on n (n:
• a natural number) consecutive pixels in accordance with an angle of the optical element based on the second direction, the first left-eye image is displayed on m (m:
• a natural number) consecutive pixels, the second right-eye image is displayed on k (k:
• a natural number) consecutive pixels, the second left-eye image is displayed on p (p:
• a natural number) consecutive pixels, and a position of at least one of a boundary between the first right-eye image and the first left-eye image, a boundary between the first left-eye image and the second right-eye image, a boundary between the first right-eye image and the second left-eye image, and a boundary between the second right-eye image and the second left-eye image is moved on the basis of first position data indicating positions of the eyes of the first observer and second position data indicating positions of the eyes of the second observer.

A stereoscopic display device for multiple observers comprising:

• an optical element configured to restrict a position where each of parallax images observed in correspondence with eyes of a plurality of observers is visually recognizable;
• a display having a display surface including a plurality of pixels arranged in a first direction and a second direction intersecting the first direction and configured to display the parallax images on the display surface;
• and
• a display controller operable to detect a relative position between the eyes of a first observer and the eyes of a second observer is detected configured to perform a control process so that
• a width of a viewpoint region where the parallax image is visually recognizable is wider than at least a distance between a right eye and a left eye of each observer,
• each parallax image is displayed on q (q:
• a natural number of 4 or more) consecutive pixels in accordance with an angle of the optical element based on the second direction, and
• the width of the viewpoint region of the parallax image is changed in correspondence with position information of each observer.
