Description

一种多峰滤色式立体图像显示方法 技术领域: 本发明是一种实现彩色立体图像的显示方法,它主要应用于摄影; 摄像及印刷制品中, 特别适用于彩色电视系统。
背景技术: 电视发展到今天, 最早出现的是色差式立体图像显示方法, 直到 现在某些游戏场景中仍在使用, 它是将左右图像信息用不同颜色的偏色片分离 开来, 使人左眼看到左边摄像机的摄影图像, 右眼看到右边摄像机的摄影图像, 由人脑来合成得到立体影像。 它的主要缺点是图像基色信息显示不全, 出现偏 色, 带色边, 不能得到正常的彩色立体图像显示, 影响收看效果。 本发明的主 要目的就是要实现彩色立体图像显示, 并谋求做到与现有彩色电视系统兼容。 发明内容: 要再现身临其境的彩色立体图像显示场景, 最少要有两部摄像机, 模拟人的双眼, 分别取得左右图像信号, 经过合成编码, 同步传送至显示端, 还原在人的左右眼里, 来再现摄像端场面。 而多峰滤色片是可以同时通过不同 单色光的滤光片, 利用它来选取所需要的基色图像, 得到左右图像画面。 因而, 左右图像, 由颜色信息组成, 其特征是用多峰滤色片来分离图像画面, 达到实 现彩色立体图像的显示效果。
现有的彩色电视图像显示系统, 是用一部摄像机, 摄取红; 绿; 兰三基色 图像信号, 经过编码合成视频信号后, 传送输出, 然后由显示器接收并解码还 原出红; 绿; 兰三基色信号。 为了使立体图像显示与现有的电视传送系统兼容。 用两部摄像机, 左右图像由红; 蓝和绿基色信号组成, 同步混合编码传送并显 示出来, 用红; 蓝双峰滤色片与绿滤色片组成滤光镜, 来分离图像画面, 实现 彩色立体图像显示。 这种方法简单实用, 能完成彩色立体图像的显示, 并且与 原有图像带宽和存储容量相当。
现有的薄膜滤色技术, 能使 90%的滤色光通过。 为了达到彩色图像信息能 够充分有效地显示出来, 就要使左右多峰滤色片上的滤色膜与左右图像像素的 颜色相互对应一致。 另外, 多通道滤色片有多种工艺制造方法, 在这里, 比效 简单实用的方法是在基片上, 由不同颜色的滤色膜相间组合, 布满基片, 大致 与显示屏的基色像素排列组合结构相类似, 然后定形成片。
不同的单色光, 透过人眼晶状体时, 由于波長不同, 不能一致到达视网膜 上, 相互间产生色差, 影响人们对不同颜色的感知水平, 加大用眼负担, 为了 使不同波長的单色光聚焦更加准确一致, 在基片上, 刻蚀小凹槽, 使各色滤色 膜的厚度或小凹槽的深度不同,来补偿不同单色光到达视网膜上出现的色差距, 从而使彩色画面更加清晰稳定。 其实, 这有点类似于光盘的生产工艺结构。
在多峰滤色片上, 当由不同颜色的滤色膜组成多通道滤色片时, 只有使相 一般釆说, 用于人眼镜面距离上的滤色片, 只要使各色滤色膜, 相间距离小于 l x l0-2mm, 就有利于人眼对画面的观赏, 相间距离越小, 图像越细腻。
现有的彩色立体图像显示方式, 主要分为两大类, 镜像式和裸眼式。 镜像 式中, 普遍使用偏光式和快门式, 它们对显示器都有不同程度的技术要求, 提 高了使用成本。 而多峰滤色式立体图像显示方法, 没有对显示器作硬性要求, 也能实现彩色立体图像显示。 因而有利于立体影像产业的发展和推广。 用多峰 滤色镜观看立体图像时, 还能有效滤除画面以外光线的干挠, 提升观看效果。 裸眼式立体图像显示方法, 它是在显示面上, 用隔板或透镜来分离左右图像画 面。这样做, 要提高图像清晰度, 对生产工艺要求非常高, 难以得到完美实现, 目前还比不上镜像式立体图像的显示效果, 使实际应用受到一定程度的影响。
多峰滤色式立体图像显示方法, 在书画影印方面, 也能得到很好的应用。 它是把左右图像画面相间分布, 用相应的滤色镜, 实现彩色图像分离。 当左右 图像像素满足人眼分辨率要求时, 就能得到清晰的立体图像, 现有的印刷制造 技术, 是不难实现的。根据四色打印机特点, 最简单的方法是左右镜像由品红; 青和黄基色组成, 它是使滤色镜和图像相互协调统一, 来实现立体图像显示。 实施方式: 随着电视技术的发展, 可在摄像端, 由两部摄像机组成, 分别摄 取红; 绿; 兰和偏移了一定波長值的偏红; 偏绿; 偏兰三基色信号组成左右图 像信息对, 用对应的三峰基色滤光片把它们分开。 之所以能这样, 是因为各基 色光都有较宽的波長范围, 而滤色片的波長带宽可以做得很窄, 形成一个滤色 窄峰带, 虽然都是红; 绿; 蓝基色光, 只要波長稍有不同, 就能把它们相亙分 选出来, 这样, 左右图像分别由红; 绿; 蓝和偏红; 偏绿; 偏蓝三基色信号组 成, 同步编码传送, 通过红; 绿; 蓝; 偏红; 偏绿; 偏蓝像素组成的显示屏显 示出来, 用红; 绿; 蓝与偏红; 偏绿; 偏蓝三峰滤色片组成滤光镜, 把左右图 像分离开来, 实现彩色立体图像显示, 这种方法彩色立体效果好, 不偏色, 不 带色边, 完全能满足现代人们对图像质量和伴音高标准的娱乐要求, 在图像信 息传送处理上, 也不存在技术障碍, 而且, 还能与现有电视系统兼容。
红; 绿; 兰; 品红; 黄; 青六基色显示屏也面市了, 它丰富了彩色效果, 但由于品红; 黄; 青混合后, 缺少亮度层次。 因而选用左右图像分别由红; 绿; 蓝和黄; 偏蓝基色信号组成, 同步编码传送, 通过红; 绿; 蓝; 黄; 偏蓝像素 组成的显示屏显示出来, 用红; 绿; 蓝与黄; 偏蓝多峰滤色片组成滤光镜, 把 图像分开, 来实现彩色立体图像显示, 它更有利于丰富色彩和提高清晰度。
在高保真彩色打印行业中, 12原色已商业化, 为了使彩色立体画面更加艳 丽, 左右镜像由红; 绿; 蓝和品红; 黄; 青基色组成, 并在画面上, 分别辅以 黑,淡青,淡品红,灰色,淡灰和光亮剂来增加层次效果, 这样不但色彩丰富, 清晰, 还提高人们的感知水平。
