Illusion photography
Everyone knows that Edison invented the electric light. Do you know what he invented?
1, movable movie camera
1889 Edison invented the movable film camera. This camera uses a pointed gear to drive the tape with the width of 19mm. Under the control of the ratchet, it drives the tape to move intermittently and punch holes at the same time. This camera is driven by a motor, and the shutter shaft is connected to the phonograph. When the camera is running, the phonograph records sound and can take pictures continuously.
2. Movable film projector
189 1 year, Edison invented the movable film projector, which is an early film projection equipment, and introduced the basic methods of film projection. The motor is used in front of the light source to make the film belt of continuous pictures rotate at high speed, thus creating the illusion of motion. The light source projects the pictures on the film onto the screen.
3, phonograph
1August 5, 877, Edison asked his assistant to make a "strange machine" consisting of a large cylinder, a crank, a receiver and a diaphragm according to the pattern. After the production, Edison took out a piece of tin foil and rolled it on a metal cylinder engraved with spiral grooves, so that one end of the needle gently rubbed the tin foil and the other end was connected with the receiver. Then Edison shook the crank and aimed it at the receiver. In February 65438, Edison publicly demonstrated this "tin foil cylinder phonograph", which caused a sensation all over the world.
4. Audio movies
19 10, Edison invented a movie camera consisting of a phonograph and a camera. Under the energy of the motor, the camera's shading crankshaft is linked with the phonograph, which can record when the camera is running. During the screening, the phonograph runs synchronously with the picture, so that sound and image appear at the same time.
These four inventions really started the film industry.
