Stereoscopic image viewing eyewear and method for controlling the viewing of stereoscopic images based on a detected distance between a display device and the eyewear
View Patent ↗Stereoscopic image viewing eyewear includes a left-eye shutter that controls a visual field of a viewer's left eye, a right-eye shutter that controls a visual field of a viewer's right eye, a distance determiner that detects a distance between the display device and the eyewear and determines whether the detected distance is smaller than a predetermined value, and a shutter controller that controls open and close of the left-eye shutter and the right-eye shutter based on the determined result of the distance determiner to cause the viewer to view the stereoscopic image when the detected distance is larger than a predetermined value, and to cause the viewer to view a non-stereoscopic image when the detected distance is smaller than the predetermined value.
1. A stereoscopic image reproducing system, comprising:
a display device that displays an image for enabling a stereoscopic image to be viewed; and
plural stereoscopic image viewing eyewear that enables a viewer to view the stereoscopic image based on the image displayed on the display device, wherein
each stereoscopic image viewing eyewear comprises:
a left-eye shutter that controls a visual field of a viewer's left eye;
a right-eye shutter that controls a visual field of a viewer's right eye;
a distance determiner that detects a distance between the display device and the eyewear and determines whether the detected distance is smaller than a predetermined value; and
a shutter controller that controls open and close of the left-eye shutter and the right-eye shutter based on the determined result of the distance determiner to cause the viewer to view the stereoscopic image when the detected distance is larger than a predetermined value, and to cause the viewer to view a non-stereoscopic image when the detected distance is smaller than the predetermined value,
each of stereoscopic image viewing eyewear has different distances between centers of a left-eye glass and a right-eye glass, and
as the distance between the centers of the left-eye glass and the right-eye glass is smaller, the predetermined value is set to a larger value;
wherein when the detected distance is smaller than the predetermined value, the shutter controller simultaneously controls the left-eye shutter and the right-eye shutter to open in synchronization with display of one of a left-eye image and a right-eye image, and simultaneously controls the left-eye shutter and the right-eye shutter to close in synchronization with display of the other image.
