电视,最现代化的视听传播工具。而它的基础原理,乃是来自它的母体——电影。电影胶片上二十四幅固定的画面,在一秒钟内闪过放影机镜头,连接出活生生的自然生活实景。电视的记录与播出方式也大致相同,能让画面运动起来,借助的是人们眼睛特有的生理现象——视觉暂留。属于技术的术语经常被延用到艺术创作的方面来。譬如,人们把摄影机开机到停机所记录下来的画面称之为一个镜头,也有人拓展了某些技术术语的内涵,将过目就忘的电影电视等作品称为“视觉暂用”。当然,这显然是指心灵或心理的视觉。 TV, the most modern audio-visual communication tool. And its basic principle, but from its mother - the film. Twenty-four fixed footage on motion picture film flashed through the lens of the projector in one second to connect with the lively natural scenery. TV recording and broadcast the same way, make the picture movement, with the help of the human eye-specific physiological phenomenon - visual persistence. The terms that belong to technology are often used in terms of artistic creation. For example, people call the footage recorded when the camera is powered on and down to a halt. It is also called a “telepresence.” Others have expanded the connotation of certain technical terms. Of course, this obviously refers to the spiritual or psychological vision.
