1. A method of reducing fatigue resulting from viewing a three-dimensional (3D) image display, the method comprising: obtaining low visual fatigue parameter information with respect to a frame section comprising at least one frame of a received 3D image; obtaining disparity vector information with respect to disparity vectors of each frame of the 3D image; determining a disparity minimum limit value and a disparity maximum limit value with respect to the 3D image; and comparing the disparity minimum limit value and the disparity maximum limit value with the obtained disparity vector information and adjusting a disparity of the 3D image.
