Description
本創作是有關於一種立體顯示裝置，且特別是有關於一種可改善視覺疲勞的立體顯示裝置。The present invention relates to a stereoscopic display device, and more particularly to a stereoscopic display device capable of improving visual fatigue.
目前的立體顯示裝置多是採用視差的方式，即讓觀看者的左眼和右眼接受到的內容不同，左眼看到的圖像和右眼看到的圖像中相同物體的位置會有偏移，使觀看者看到立體圖像。但是，為了使觀看者看到強烈震撼的立體效果，往往會在原有的立體視訊上加大立體視訊的景深以增大視差，可是較大的視差容易使觀看者產生視覺疲勞以及引起頭暈噁心等不舒服的狀況，給觀看者身體健康造成不良影響，甚至導致死亡。雖然有些立體顯示裝置通過一些方式去改善觀看者的視覺疲勞，但是其實現方式是通過觀看者的觀看時間和立體視訊的視差是否較大來判斷觀看者的視覺疲勞，而忽略了不同觀看者可以承受的視差大小是不同的。Most of the current stereoscopic display devices adopt parallax method, that is, the content received by the left eye and the right eye of the viewer is different, and the position of the same object in the image seen by the left eye and the image seen by the right eye may be offset. To allow viewers to see stereoscopic images. However, in order to enable the viewer to see a strong and powerful stereoscopic effect, the depth of field of the stereoscopic video is often increased in the original stereoscopic video to increase the parallax, but the larger parallax is likely to cause visual fatigue and dizziness and nausea to the viewer. Uncomfortable conditions can adversely affect the viewer's health and even lead to death. Although some stereoscopic display devices improve the visual fatigue of the viewer in some ways, the implementation manner is to judge the visual fatigue of the viewer by the viewing time of the viewer and the parallax of the stereoscopic video, and ignore the different viewers. The amount of parallax that is tolerated is different.

When the stereoscopic video input to the stereoscopic display device includes the original depth image and the original two-dimensional image, the new depth image that is most suitable for the viewer to view can be calculated according to the viewer's pupil distance and the original depth image, and then the original two are combined. The dimensional image generates an image of a desired viewing angle (ie, N different viewing angle images), which improves the stereoscopic effect of the stereoscopic video. By adding the feature of the viewer's distance, the creation can make the viewer watch the stereoscopic movie more comfortable and healthy.
