When was the camera made?

1874, Jules Jean Sang of France invented the camera.

He wound the film on a toothed supply reel.

Under the control of the pendulum mechanism, the film supply tray moves intermittently in the circular film supply box, and at the same time, the pendulum mechanism drives the shutter to rotate. Whenever the film stops, the shutter is opened for exposure. Janssen connected this camera to a telescope, which can take a set of photos of planetary motion at the speed of one per second. Janssen named it a photographic gun, that is, a modern movie camera +Y6R.

1882, Jules Marie of France invented a camera, which can shoot the coherent movements of birds, thus giving birth to photography technology. This camera is shaped like a gun. A round box similar to a large magazine is fixed at the trigger, and a large caliber barrel is installed in front. A glass photosensitive disc coated with silver bromide emulsion is installed in the round box. When shooting, the photosensitive disc intermittently moves in a circle, and the shutter is coaxial with the photosensitive disc and keeps rotating, blocking and absorbing the light beam passing through the lens. The whole machine is driven by a clockwork. You can take photos with the exposure speed of1100 seconds and the frequency of 12 photos per second. 1888, Marley invented a new camera. He replaced the fixed photosensitive disc with a photosensitive paper tape wound on the shaft. When the photosensitive paper tape passes through the focus of the lens, two color grasping mechanisms fix the photosensitive paper tape to expose it. Later, Marley replaced the photosensitive paper tape with photosensitive film. Marley's camera has been continuously improved, and finally it can shoot at a frequency of 60 shots per second on a 9 cm wide film.

1889, Edison in America invented the camera. This camera is driven by a pointed roller 19 mm wide non-porous adhesive tape. Under the control of the ratchet wheel, the adhesive tape is driven to move intermittently and punch holes at the same time. This camera is driven by a motor, the shutter shaft is linked with the phonograph, and the phonograph records the sound when the camera is running. On this basis, the mobile camera was invented. There is a cross wheel mechanism in the camera to control the intermittent motion of the film, and another gear drives the film forward. This camera uses 35 mm perforated film.

Japan's JVC is the inventor of the world's first camera, so it is called the father of the camera.

Baird, Scotland, 1925, after careful design, uses old radio equipment, old candy boxes, bicycle lamp lenses, old wires and other waste materials to manufacture the world's most primitive TV cameras and receivers. 1On October 27th, Baird presented his invention to 40 scientists at the Royal Society in London, England. He put a TV in one room, and the scientists watched TV in the other room. The picture of a man talking while smoking appears on the screen. This performance was later recognized internationally as the first public television broadcast.

From 65438 to 0929, American scientist eves played 50 lines of color TV images between new york and Washington, and invented color TV. 1933, Zworykin successfully developed camera tubes and picture tubes for TV camera shooting. The process of making TV camera and imaging completely electronic has been completed, and so far, the modern TV system has basically taken shape. Today, the imaging principle and equipment of TV cameras and TV receivers are improved according to his invention.

1936165438+1On October 2nd, the British Broadcasting Corporation (BBC) broadcast a large-scale song and dance program in Alexandria Palace, a suburb of London, and launched a two-hour TV broadcast for the first time. The coverage of the Berlin Olympic Games that year was a great appearance of young TV career. At that time, * * * used four cameras to shoot the game. One of the most striking is the all-electronic camera. This machine is huge. The lens with a focal length of1.6m weighs 45kg and is 2.2m long. It is called TV cannon.
