在开关眼镜式和偏振光眼镜式2种立体液晶电视中进行视觉感知实验,通过改变测试图像的景深和空间频率,研究了眼镜式立体电视中立体图像的视差对人眼对比灵敏度感知阈值的影响.实验中共选用3种景深和10种空间频率的图像.实验结果表明,液晶电视中显示的二维图像与传统成像方法显示的二维图像在不同空间频率处对人眼对比灵敏度阈值的影响不同.2种立体液晶电视中三维模式下显示的立体图像和二维模式下显示的平面图像,对人眼对比灵敏度阈值有显著性影响.但在三维显示模式下,不同景深的立体图像对人眼对比灵敏度感知阈值的影响不显著.

Visual perception experiments were made on two kinds of stereoscopic liquid crystal display(LCD), shutter glasses (SG) and film patterned-retarder (PR), to study the influence of different depths of the field and spatial frequencies on contrast sensitivity (CS) threshold. In experiments, three depths of field and ten spatial frequencies were selected. The experimental results indicate that the 2D image displayed on LCD and showed by the conventional optic method have different effects on CS threshold within different spatial frequency ranges. T...
