Answer :
Edison and his assistant, WIlliam Dickson, grew worried that others were gaining around in camera development, such as Eadweard Muybridge. Muybridge presented the idea of collaborating to create a movie camera, but Edison turned him down. He planned to do this by using Edison's Phonograph and his Xoopraxiscope, a device for projecting motion pictures that pre-dated the flexible perforated film strip.
Edison's Movie Camera, also known as the "Kinetograph" finally came together in 1891. The movie camera takes a sequence of photographs in order to give the illusion of motion when viewed in rapid succession.
