ABSTRACT

With the rapid development of the global film industry, film projection technology plays an increasingly prominent role in order to enhance the performance of film images and sound and enhance the interactive feeling of the audience. In order to accurately grasp the film shows the development of technology, puts forward a research method based on patent analysis study of film screening technology, the method from the trend of the global patent application, patent application for geographical, the main technology such as three angles were studied on the development of film technology, analyzes the development trend of related patent applications and the distribution of the technology, the technology has been clear about the movie is the main development direction. Through the analysis of global patent data, we can accurately grasp the development trend and characteristics of the field of film projection technology in the future, which has reference value and function for the development of film projection technology in the future.
