Apparatus for recovering eyesight utilizing stereoscopic video and method for displaying stereoscopic video

摘要

This invention provides a stereo image displaying method and eyesight recovery apparatus which stimulates the eye muscles and is inexpensive and simple. An image for the left and the right eye are displayed on the screen 50 of an electronic device 2 alternately, an observer wears spectacles 4 which open and close in synchronism with the display of these images to produce a convergence angle and parallax to obtain a 3-D image. A 3-D image display device is used to enable the observer to focus his/her right and left eyes on the images of a 3-D image. A 3-D image 10a is displayed at a position close to the spectacles 4 and then gradually moved away from it. The eyesight recovery apparatus comprises a movement control unit 10 for moving a 3-D image 10b at a distance close to the spectacles 4 and a repetition control unit 23 for repeating the receding and approach movements. When the observer wearing the spectacles 4 tries to always focus on the 3-D images 10a and 10b on the screen 50, his/her ciliary bodies and eyeball moving muscles around his/her eyes are stimulated, thereby recovering his/her eyesight.
