Apparatus and method for reducing three-dimensional visual fatigue
First Claim
Patent Images
1. An apparatus reducing three-dimensional (3D) visual fatigue, the apparatus comprising:
- a viewing distance estimator (detector) to estimate (detect) a user-to-screen distance from a screen to a user;
a 3D image analyzer to calculate a user-to-3D object distance based on the estimated user-to-screen distance and a parallax of a 3D image;
a 3D visual fatigue predictor to predict 3D visual fatigue of the user based on the estimated user-to-screen distance and the calculated user-to-3D object distance; and
a 3D image controller to control the 3D image based on the predicted 3D visual fatigue.

Abstract
Disclosed are an apparatus and method for reducing 3D visual fatigue that a user feels when viewing a 3D image. An optimal 3D image may be regenerated and displayed without causing 3D visual fatigue and thus, it is possible to significantly reduce the 3D visual fatigue.
