Movie theatre multi-subtitle system based on psychological visual modulation display technology and method thereof

Abstract

The invention discloses a movie theatre multi-subtitle system based on the psychological visual modulation display technology and a method thereof. The system comprises a display device and an auxiliary watching device which is matched with the display device. A group of composition bases comprising video contents and different languages of subtitles are arranged according to specific time and space and played by the display device, and the composition bases played in any time and areas are common component parts of multiple images or component parts of one image. Time domain or spatial domain amplitude modulation is performed on the composition bases played by the display device by the auxiliary watching device. The modulated information is finally integrated into the required images in the human brain via a user human eye visual system. According to the characteristics of constantly increasing refresh frequency and spatial resolution of the existing display devices and the limited resolution of human eyes under certain observation distance, the display device and the auxiliary watching device which is matched with the display device and can be customized according to the requirements are adopted so that the movie theatre multi-subtitle system is realized.

Description

technical field [0001] The present invention relates to a system in the technical field of signal and image processing, in particular to a cinema multi-subtitle system and method based on time and space domain psychovisual modulation information display technology. Background technique [0002] In the era of internationalization, more and more international film festivals are held around the world. Foreign language films are becoming popular. There are more opportunities for audiences from different countries to watch the same movie together. The existing solution is to stack subtitles in other languages ​​such as English on top of the local language subtitles. However, this solution has disadvantages: when the number of subtitle languages ​​that need to be displayed simultaneously is large, the stacked subtitles may cover nearly half of the screen, affecting the audience's experience. Therefore, a theater multilingual subtitle system that better preserves the viewing exp...

Problems solved by technology

However, studies have shown that the temporal and spatial resolution of the human visual system is limited at a certain viewing distance

In the time domain, the human eye cannot distinguish optical signals exceeding the critical flicker frequency (about 60Hz), and in the air domain, it cannot distinguish images with a pixel density exceeding 200PPI at a normal viewing distance
