活动电影放映机（Kinetoscope）是一种早期电影显示设备，器件被放置在一个橱柜里，只能允许一个人通过小窗口观看电影。活动电影放映机引入了电影放映的基本方法，该方法于影片发明前被所有电影放映机采用。它通过在一个光源前高速转动带有连续图片的电影胶片条，从而产生活动的错觉。1888年美国发明家托马斯·爱迪生最早提出这个概念，后来他的员工威廉·肯尼迪·迪克森在1889年和1892年之间极大程度地发展了这个技术。迪克森和他在爱迪生实验室的团队也同时设计了活动电影摄影机，这是一个创新的电影摄影机，可以连续地拍摄图像。在内部试验拍摄电影后，商业的活动电影放映机最终诞生了。

The Kinetoscope is an early motion picture exhibition device. The Kinetoscope was designed for films to be viewed by one individual at a time through a peephole viewer window at the top of the device. The Kinetoscope was not a movie projector but introduced the basic approach that would become the standard for all cinematic projection before the advent of video, by creating the illusion of movement by conveying a strip of perforated film bearing sequential images over a light source with a high-speed shutter. A process using roll film first described in a patent application submitted in France and the U.S. by French inventor Louis Le Prince, the concept was copied by U.S. inventor Thomas Edison in 1889, and subsequently developed by his employee William Kennedy Laurie Dickson between 1889 and 1892. Dickson and his team at the Edison lab also devised the Kinetograph, an innovative motion picture camera with rapid intermittent, or stop-and-go, film movement, to photograph movies for in-house experiments and, eventually, commercial Kinetoscope presentations.
