Abstract: The image as the important part in the image system is the visual presentation, replication and fixed of the real world with some technical media, mainly including photographic images, film, TV images and video images, etc. In the image system, image roughly undergoes three stages:“from painting to photography”,“from photography to film” and “from the movie to TV”. This course is an evolution process of representation and communication of the modern visual symbols, ultimately the result of humans to contact with，understand and reflect reality, and the portraiture of different dependent relationships between humans and reality.
