History of videocamera?

Question

I've got a problem with my home work. I need the whole history of how videocameras made thier start and together with that I need to know its construction.

Answer 1

Charles P. Ginsburg

Charles Ginsburg led the research team at Ampex Corporation in developing the first practical videotape recorder (VTR). In 1951, the first video tape recorder (VTR) captured live images from television cameras by converting the information into electrical impulses and saving the information onto magnetic tape. Ampex sold the first VTR for $50,000 in 1956.The first VCassetteR or VCR were sold by Sony in 1971.

He led the Ampex research team that developed a new machine that could run the tape at a much slower rate because the recording heads rotated at high speed, allowing the necessary high-frequency response.

Video Recording
In the early days, film was the only medium available for recording television programmes. Thoughts turned to magnetic tape, which was already being used for sound, but the greater quantity of information carried by the television signal demanded new studies. During the 1950s, a number of American companies began investigating the problem.

Television Cameras
In the 1920s, American engineer, Philo Taylor Farnsworth devised the television camera, an image dissector, which converted the image captured into an electrical signal.

Television Cameras
The pick-up tube is the main element governing the technical quality of the picture obtained by the camera. The first electronic cameras using iconoscope tubes were characterised by very large lenses, necessary to ensure enough light reached the pick-up tube.

Video Stills - Digital Photography
The still video or digital camera (the Sony Mavica single-lens reflex) was first demonstrated in 1981. It used a fast-rotating magnetic disc, two inches in diameter, recording on it up to 50 images formed in a solid-state device in the camera. The images were played back through a television receiver or monitor, or printed out.

The History of Recording Technology
Tape Recording Technology - Audio and video magnetic recording has had greater impact on broadcasting than any other single development since the invention of radio/TV transmission itself.


VHS - Video tape in a large cassette format introduced by both JVC and Panasonic around 1976. This has been the most popular format for home use and video store rentals, however, it will be replaced by mini dv tapes and dvds. VHS stands for Video Home System.

Answer 2

In a nutshell:

Several thousand years ago, people discovered that images would form on a wall when you punched a hole in a dark room (true fact). Later, painters used small "dark rooms" to help them paint. Finally a person (I forgot his name), discovered a way to collect the light on a surface to form an image. Then thomas edision had an idea of shooting several pictures each second so they looked like they moved. But this wasnt good enough, so one day another person found a way to record light by electronic means. Then they invented all the different formats, cameras, blah blah blah, and thats how we get all the format wars, and SD vs. HD and stuff like that. The end.

The long version:
Go to wikipedia and search for video camera.
