摘要

为了优化主动快门式立体显示中的闪烁现象,对环境光的影响进行了深入的研究。研究中使用高采样率瞬态亮度响应测量系统对透过快门眼镜的环境光信号进行实时测量和记录,测量的时域信号经过傅里叶变换后得到对应的频域信号,用来分析环境光影响闪烁的可能原因。同时,基于多参数可调的发光二极管(LED)照明系统完成了两组视觉感知实验,结果表明,环境光的频率、最大光强、占空比以及显示器的显示内容等参数对人眼透过快门眼镜感受到的环境光闪烁程度有显著性的影响,120 Hz或以上的倍频光作为匹配环境光可以消除环境光闪烁并且达到比较好的舒适度。研究结果对主动快门式立体显示中闪烁感的优化以及视觉舒适度的提高具有指导和推动作用。

Abstract

To optimize the flicker phenomenon in active shutter type stereoscopic display, the influence of ambient light is deeply investigated. The transient luminance response measurement system with high sampling rate is used to measure and record ambient light through shutter glasses in real time. The measured time domain signal is transformed into frequency domain through Fourier transformation for the analysis of possible flicker source. Meanwhile, two perception experiments are implemented based on the multi-parameter adjustable light emitting diode (LED) lighting system. The experiment result shows that the involved factors such as frequency, maximum intensity, duty cycle and displayed image on the display, all have significant effect on the ambient light flicker felt by human eye through shutter glass, and 120 Hz or higher times frequency as matching ambient light can eliminate the flicker caused by ambient light and accomplish better visual comfort. The investigation result guides and facilitates the optimization of flicker in stereoscopic display with active shutter glasses and the improvement of visual comfort.
