From the development trend around the world, new 3D movie sources are more and more abundant, and 3D channels of television are more and more. How to make people watch 3D programs at home, on business trip, and in office anytime and anywhere is obviously a topic of interest in the industry. Traditionally, 3D programs can only be viewed in 3D cinema or in front of a 3D television set. If a viewer can watch 3D programs on a common television or a common computer through some viewing aid device, the problem of watching the 3D programs anytime and anywhere can be solved at low cost. The red and blue glasses (more generally, the "complementary glasses") are a stereoscopic vision aid with a long history, but have poor color fidelity and cause temporary color vision disorder of a viewer (problems caused by long-term use and still need to be researched and observed). Recently, several 3D vision aids with high color fidelity are available on the market, such as "screen glasses", "3D video partners", etc., which all display 3D signals on a common display device in a left-right format, and when a viewer views a display screen through the vision aids, a left-eye parallax image and a right-eye parallax image (hereinafter referred to as "left-eye image" and "right-eye image") move to the middle in opposite directions and overlap each other, so that a stereoscopic image is formed in the brain of the viewer. The visual aid devices of this mechanism have a common defect that the visual angle magnification is 1, the size and the length-width ratio of the image seen by the viewer are the same as those of the screen display, and the stereoscopic image finally perceived by the viewer is only half of the width of the display screen at most because of the left-right format display. If the height of the display is full, the image seen by the viewer becomes slender (the height is unchanged and the width is compressed by half); if the height of the display is also compressed by half, the ratio of the length to the width of the image becomes harmonious, but the height and the width of the image are reduced by half, and the area is only one fourth of the full screen. As is known, when viewing 3D images, the larger the image, the more shocking the effect, so that although the viewing aid device with this mechanism realizes high fidelity of 3D image colors, the smaller the viewing image, the less desirable the viewing effect.
