项目摘要

We investigated the method to evaluate the binocular stereoscopic image systems using binocular disparity from the view point of visual function and autonomic nervous systemOptometric testing of visual function is considered to be suitable for objective evaluation of visual fatiguewhen viewing a stereoscopic display. The testing terms in visual function are as follows. Uncorrected visual acuity. Corrected visual acuity, . Subjective refraction, Objective refraction, Phoria (eye position), Near vision point, Ability of visual accommodation, Interocular pressure and Tear flow.From the result of the visual function test and interview investigation, there are large differences between 2D and 3D displays. Therefore, both the visual function test and interview method are valid for evaluating the influence on the human eye. I think that *e symptoms relate closely to the changes in visual functions, but it is difficult to discuss the relation between visual functions and symptom in interview i … More nvestigation clearly. From the results of visual function, it is indicated that 3D display affects vergence, phoria and visual accommodation. It is reported that the vergence and accommodation occurs simultaneously and accommodation shows unstable response^5, convergence break down sometimes^7. From those experimental results, accommodation and convergence are induced by the reconstructed position of a 3D image. And it is considered that this unstable phenomena in accommodation cause discomfort feeling and visual fatigue. It is suggested that the improvement in the imbalance between vergence and visual accommodation reduces a discomfort feeling and visual fatigue.The evaluation method using visual function test and interview investigation proved to be very satisfactory for analyzing the influence of stereoscopic imaging systems on the visual function and visual fatigue of eyes. Visual fatigue is more intense when viewing stereoscopic images. Change in accommodation and phoria of stereoscopic images are larger in magnitude than for two dimensional images. Many factors as 3D expression method and quality of image may affect discomfort felling and visual fatigue, but it is expected that the improvement in display method and image quality decrease those.

本文从视觉功能和自主神经系统的角度探讨了利用双眼视差来评价立体视觉系统的方法。视功能的验光测试被认为适合于客观评价观看立体显示器时的视疲劳。视觉功能的测试术语如下。裸眼视力。矫正视力，。主观验光、客观验光、隐斜视（眼位）、近视点、视调节能力、眼压、泪液流量，从视功能测试和访谈调查的结果来看，2D和3D显示器之间存在较大的差异。因此，视功能测试和访谈法均适用于评估对人眼的影响。我认为，视功能的改变与眼症状密切相关，但在访谈中很难讨论视功能与眼症状的关系， ...更多信息调查清楚。视觉功能测试结果表明，3D显示对人眼的聚散度、隐斜视和视调节均有影响。据报道，聚散和调节是同时发生的，调节表现出不稳定的反应^[5]，会聚有时会中断^[7]。根据这些实验结果，调节和会聚由3D图像的重建位置引起。这种不稳定的调节现象被认为是引起不适感和视觉疲劳的原因。结果表明，改善了聚散度和视调节的不平衡，减轻了不适感和视疲劳，采用视功能测试和访谈调查的评价方法，分析了立体成像系统对眼睛的视功能和视疲劳的影响，结果令人满意。当观看立体图像时，视觉疲劳更强烈。立体图像的调节和隐斜视的变化在幅度上大于二维图像。3D表现方法和图像质量等许多因素可能会影响不适感和视觉疲劳，但预计显示方法和图像质量的改进会降低这些因素。少
