In three-dimensional displays, large verticalparallax in parallax images is disadvantageous to stereo vision due to the presence of visual fatigue.
立体显示时，视差图像中过大的竖直视差将对人眼立体视觉造成干扰，容易使观看者产生视觉疲劳。

Rainbow holography is a major method in white-light holography, which is lack of verticalparallax due to introducing a slit that reduces the view zone of reconstructed images in recording process.
Based on the principle that homologous points in different parallax images correspond to the same object point, a method is proposed to eliminate the verticalparallax in multi-view parallax images.
