中文摘要: 提出了一种通过纠正平面显示屏上合成图像子像素亮度值来使得柱透镜光栅自由立体显示器相邻视点间的显示图像串扰消除的方法。针对合成图像分析其串扰的产生原因,并根据合成图像上显示的子像素亮度值、透过光栅观看到的子像素亮度值以及视点间的串扰系数3者之间的关系,推导出消除串扰的计算公式并实验证实了该方法的正确性。

Abstract:A method used to eliminate the crosstalk between the neighboring parallax images by correcting the intensity values of subpixels on synthetic images in the autostereoscopic displays was proposed based on lenticular sheet. The causes of the crosstalk was analyzed based on a synthetic image, and the equations of crosstalk elimination was deduced according to the relationship among the crosstalk coefficients of each parallax image observed through the lenticular sheet, the intensity values of subpixels displayed on the synthetic images, and the intensity values of subpixels observed through the lenticular sheet at the optimal viewing position. The experiment results verified the effectiveness of the proposed method.
