基于棱柱镜技术的自由立体显示图像合成

根据棱柱镜的光学和物理结构以及LCD子像素的排列特征,提出了一种用于棱柱镜自由立体LCD显示的多视点合成新方法.该方法属于数字合成算法,由子像素判断准则、视点视图下采样以及多视点子像素的排列3部分组成.将该方法与传统模拟光筛合成方法和常规数字合成方法进行比较,实验结果证明新方法在合成速度和观看效果上优于后两种方法.同时,由于该方法对各视点视图进行了下采样,大幅减少了原始数据量,十分有利于压缩.

Image Synthesizing for Autostereoscopic Display Based on Lenticular Technology

Based on the optical characteristic and physical structure of lenticular as well as the alignment characteristic of LCD sub-pixels,a multiview synthesizing method for lenticular autostereoscopic LCD display was proposed.The method belongs to digital synthesizing method and is composed of three parts:sub-pixel judgment rule,view down-sampling and alignment of multiview sub-pixel.By comparison,the proposed method is more advantageous than the traditional analog mask synthesizing method and the general digital synthesizing method both in synthesizing efficiency and viewing effect.Furthermore,since down-sampling is made for each view,the proposed method reduces the original amount of data,which is beneficial to compression.
