本发明实施例提供的一种 3D显示方法, 包括如下步骤:
5101、 3D显示装置将 2D图像通过预设算法转换成左眼图像和右眼图像, 其中左眼图像与右眼图像是具有视差的一对立体图像对。
本发明实施例所提出的 3D显示方法,需要结合 3D显示装置中的显示面 板的结构进行说明。 如图 1所示, 3D显示装置的显示面板 10包括矩阵排布 的多行像素, 多行像素包括奇数行像素 101和偶数行像素 102, 其中奇数行 像素 101包括奇数行像素 101的第一子像素 1011和第二子像素 1012, 偶数 行像素 102包括偶数行像素 102的第一子像素 1021和第二子像素 1022。 在 3D显示装置工作时, 如果需要显示 2D图像, 则奇数行像素 101和偶数行像 素 102均显示同一图像,如果需要显示 3D图像,则需要首先将 2D图像通过 预设算法转换为具有视差的左眼图像和右眼图像, 奇数行像素 101和偶数行 像素 102分别显示左眼图像和右眼图像, 其中, 左眼图像与右眼图像之间具 有视差, 且该左眼图像和右眼图像均为完整图像。
这里, 将 2D图像转换成 3D图像的预设算法可以为例如立体匹配算法。 这样, 将一个像素划分成为两个子像素, 增加了像素点的数量, 从而提 高了图像显示的清晰度, 解决了现有技术中图像清晰度低的问题。
需要说明的是, 为什么要将 2D图像通过预设算法转换为具有视差的左 眼图像和右眼图像: 现实生活中, 人们是通过两只眼睛来观看物体的, 由于 人的左右目艮之间有一定的间距(人的两眼分开约 6.35厘米), 因此看任何一 件物体两眼的角度都不会相同。 当分别用左右眼观看一个物体时, 会感觉物 体有一些小小的位移, 经视网膜传到大脑里, 产生远近的深度, 从而产生立 体感。 这里 3D图像显示就是利用了人左右眼瞳距在大脑形成的视差产生立 体感的原理, 将左右两幅具有视差的影像投射到屏幕上, 观看者通过左右眼 分别看到连续的左右两幅影像, 从而形成了立体影像。
本发明实施例并不对 3D显示装置如何将 2D图像转换为 3D图像进行限 制, 即可以通过多种算法将 2D图像转换为 3D图像。
备选地,如果需要显示的图像本身即为 3D图像,则可以省略步骤 S101。
5102、 3D显示装置读取左眼图像中的第一左眼图像和右眼图像中的第 一右眼图像到緩存, 其中, 第一左眼图像为左眼图像的奇数行图像, 第一右 眼图像为右眼图像的奇数行图像。
在将 2D图像转换为左眼图像和右眼图像后, 3D显示装置读取左眼图像
中的第一左眼图像和右眼图像中的第一右眼图像到緩存, 其中, 第一左眼图 像为左眼图像的奇数行图像,第一右眼图像为右眼图像的奇数行图像。 即 3D 显示装置分别将左眼图像的奇数行图像提取出来, 作为第一左眼图像, 将右 眼图像的奇数行图像提取出来, 作为第一右眼图像。
S103、 3D显示装置驱动奇数行像素的第一子像素显示第一左眼图像, 驱动偶数行像素的第一子像素显示第一右眼图像, 驱动奇数行像素的第二子 像素显示黑图像, 驱动偶数行的第二子像素显示黑图像。
3D显示装置在将第一左眼图像和第一右眼图像提取出来后,会驱动奇数 行像素的第一子像素显示第一左眼图像, 驱动偶数行像素的第一子像素显示 第一右眼图像。 优选地, 为了有效防止上一帧图像对本帧图像的干扰, 同时 驱动奇数行像素的第二子像素显示黑图像, 驱动偶数行的第二子像素显示黑 图像, 即进行插黑帧处理, 有效防止信号间的串扰。 当然, 也可以不进行插 黑帧处理, 此时显示效果会比较差。
5104、 3D显示装置读取左眼图像中的第二左眼图像和右眼图像中的第 二右眼图像到緩存, 其中, 第二左眼图像为左眼图像的偶数行图像, 第二右 眼图像为右眼图像的偶数行图像。
具体地, 3D显示装置读取左眼图像中的第二左眼图像和右眼图像中的第 二右眼图像到緩存, 其中, 第二左眼图像为左眼图像的偶数行图像, 第二右 眼图像为右眼图像的偶数行图像, 即 3D显示装置分别将左眼图像的偶数行 图像提取出来, 作为第二左眼图像, 将右眼图像的偶数行图像提取出来, 作 为第二右眼图像。
5105、 3D显示装置驱动奇数行像素的第二子像素显示第二左眼图像, 驱动偶数行像素的第二子像素显示第二右眼图像。
具体地, 3D显示装置在将第二左眼图像和第二右眼图像提取出来后,会 驱动奇数行像素的第二子像素显示第二左眼图像, 驱动偶数行像素的第二子 像素显示第二右眼图像。 优选地, 为了有效防止上一帧图像对本帧图像的干 扰, 同时驱动奇数行像素的第一子像素显示黑图像, 驱动偶数行的第一子像 素显示黑图像, 即进行插黑帧处理, 有效防止信号间的串扰。 当然, 也可以 不进行插黑帧处理, 此时显示效果会比较差。
由于人眼的视觉暂留, 将奇数行图像的第一左眼图像、 第二左眼图像,
以及偶数行图像的第一右眼图像、 第二右眼图像综合在一起, 可以得到左眼 图像和右眼图像, 解决了现有技术中 3D显示图像的信息量减半的问题。
需要注意的是, 本发明实施例只是示例性地指出 3D显示装置先显示第 一左眼图像和第一右眼图像, 后显示第二左眼图像和第二右眼图像, 根据实 际显示的需要也可以对图像显示的先后顺序进行调整, 本发明不做限制。
另外, 本发明的实施例示例性地指出左眼图像由奇数行像素显示、 右眼 图像由偶数行像素显示, 但本发明的实施例不限于此, 左眼图像也可以由偶 数行像素显示, 而右眼图像也可以由奇数行像素显示。
S106、 3D显示装置循环执行步骤 S102、 S103、 S104、 S105 , 直到所有 图像显示完毕。
根据步骤 S102至步骤 S105的描述, 3D显示装置循环执行步骤 S102至 步骤 S105进行工作, 直到图像显示完毕。
本发明实施例提供的一种 3D显示方法, 通过在读取左眼图像中的第一 左眼图像和右眼图像中的第一右眼图像到緩存, 驱动奇数行像素的第一子像 素显示第一左眼图像, 驱动偶数行像素的第一子像素显示第一右眼图像后, 读取左眼图像中的第二左眼图像和右眼图像中的第二右眼图像到緩存, 驱动 奇数行像素的第二子像素显示第二左眼图像, 驱动偶数行像素的第二子像素 显示第二右眼图像, 左眼图像(即, 奇数行图像)和右眼图像(即, 偶数行 图像) 以前后两帧连续的方式显示。 通过该方案, 由于人眼的视觉暂留, 将 奇数行图像和偶数行图像综合在一起,可以将原有图像的信息全部反映出来, 因此避免了现有技术中 3D显示图像的信息量减半的问题。
