Apparatus and method for reducing three-dimensional visual fatigue

摘要

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.

主权项

1. An apparatus reducing three-dimensional (3D) visual fatigue, the apparatus comprising:
a viewing distance estimator to determine 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 determined 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 determined 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, wherein the 3D visual fatigue predictor comprises: a 3D visual fatigue model-based predictor to predict 3D visual fatigue based on a 3D visual fatigue model using the calculated user-to-3D object distance and determined user-to-screen distance, wherein the 3D visual fatigue model comprises 3D visual fatigue information regarding at least one user-to-screen distance and at least one user-to-3D object distance; a fatigue-causing determiner to determine whether the 3D visual fatigue model indicates an occurrence of 3D visual fatigue based on the predicted 3D visual fatigue, wherein the fatigue-causing determiner determines an occurrence of 3D visual fatigue if the predicted 3D visual fatigue is equal to or greater than a predetermined reference value; and an optimal user-to-3D object distance calculator to calculate an optimal user-to-3D object distance using the determined user-to-screen distance and at least one user-to-3D object distance from the 3D visual fatigue model, when the predicted 3D visual fatigue is equal to or greater than the predetermined reference value.
