The stereoscopic vision comes from the visual difference between the left eye and the right eye, when the left eye and the right eye respectively acquire the left visual image and the right visual image by means of instruments, the human brain can make image recombination through habitual visual reaction, so that the stereoscopic image is acquired, and the stereoscopic effect of most of the existing stereoscopic film and television, images, glasses and the like is acquired by the principle.
The active shutter type stereo glasses has a control circuit for controlling the black and white liquid crystal display screens to alternately change the stroboflash into black and white effects. When the special player alternately plays the left eye picture and the right eye picture at the speed of 120 frames per second, the glasses respectively block the light of one of the glasses from transmitting at the corresponding time by synchronous alternate stroboflash so as to achieve the effect of separating the left eye visual image and the right eye visual image, thereby achieving the three-dimensional effect. The technical core is that the switches of the left and right lenses of the glasses are strictly synchronous with the playing equipment, so that the 3D left and right frame switching action can be completed. Based on the theory, when playing a 3D left and right picture, the stereoscopic playing device is required to strictly send the frame synchronization signal to the glasses, and after receiving the signal, the glasses complete the decoding synchronization. The invention provides a novel synchronization system.
