Digital movie projection method, device and system

Abstract

The invention provides a digital movie projection method. The digital movie projection method comprises the steps that received image digital signals are converted into optical signals through a digital imager, light is projected into the eyes of a human body through an imaging lens arranged in front of the eyes of the human body so as to form a huge-screen virtual image corresponding to an image, and therefore digital movie projection can be realized without a screen. The digital movie projection method saves the cost of the screen; the size of the space of a movie hall is not limited, the effects of a huge screen can be realized by using a small movie hall, and therefore the operation cost is lowered; meanwhile, the space of the movie hall can be effectively used for placing seats, the space between the screen and the front row of seats does not need to be reserved, and therefore the seat occupancy rate is increased; in addition, due to the fact that the virtual huge-screen image is formed by projecting the image into the eyes at a near distance, the movie watching effects in various regions of the movie hall are uniform and the movie watching quality is unrelated to the movie watching positions.

Description

technical field [0001] The invention belongs to the technical field of digital movies, in particular to a digital movie projection method in a digital cinema. Background technique [0002] Digital movie projection is based on the principle of optical imaging. At present, digital movie projectors mainly use two projection technologies, one is digital micromirror (DMD) technology, and the other is reflective liquid crystal on silicon (LCOS) technology. [0003] The digital micromirror technology is to arrange 800,000 to 1 million small mirrors on the DMD chip, and each small mirror can independently flip 10 degrees in the positive and negative directions, and can flip 65,000 times per second. The light source is reflected by these small mirrors onto the screen to directly form an image. Therefore, DMD imaging technology abandons the optical convergence in the traditional sense, and can change the focus at will, which is very convenient to adjust, and its optical path is quite...

In addition, with this projection method, the best viewing position of the theater is limited to a local area in the center of the theater. In other viewing areas, the screen you see will have a certain offset and deformation, which will affect the viewing effect.
