Description

The present invention relates to various types of display screens and pictures (such as televisions, video cameras, video discs, closed-circuit televisions, electron microscope display screens, various display terminals, various types of pictures, photos, transparent films, slideshow pictures...) Optical system for high-definition stereoscopic images.

At present, stereoscopic televisions are of a great variety, and most of them have their own disadvantages. They are based on the principle of complementary red and green colors. The real spatial relationship and original color of the original subject cannot be realized. Alternately mirroring the left and right picture systems (such as intermittently blocked glasses, etc.), because each eye watches half of the original total number of fields, so there is a sense of flickering. Image clarity is reduced and TV stations need to make changes accordingly. The invention is simple and easy to operate, the TV station does not need to be changed, the cost is low, and the three-dimensional relationship of the original subject can be truly reproduced, the color is not distorted, the image is not lost, and there is no flickering, and because of the double-screen synthesis, the definition is greatly improved compared with ordinary TV. .

The purpose of the present invention is to use a simple optical system to make various display screens and screens produce high-definition stereoscopic images.

The invention is realized in this way: the left and right views of various display screens and pictures pass through a group of plane mirrors (or without plane mirrors), half-transparent mirrors, polarizing films, or use two specially made The louver-like baffle group, or relying on the specific size and position of the background light, makes the virtual images and real images (or virtual images) of the left and right views overlap. The viewer wears a pair of polarized glasses within the viewing range, or does not wear them. With special glasses, you can see stereoscopic images.
