The Birth Background Of Digital Camera
- Jan 17, 2018 -

Labs were tested in 1970.

The CCD array was developed by the Jet Propulsion Laboratory in 1972, and the dimensions are 100*100 pixels. The commercial CCD was also launched by Fairchild Company in the same period. The CCD gain at that time was very low, only a percent fraction, slightly higher than the photographic film.

A black-and-white image of a child and puppy was captured by a CCD sensor in a Kodak laboratory in Rochester, New York, in 1975, recorded on a cassette tape. This is the world's first digital camera to obtain the first digital photos, the development of the image industry has changed. 30 years later, the inventor behind the first digital camera came to China to review that history, and to look forward to the future of digital imagery with his keen insight.

Steven Sasson, after graduating from his master's degree in 1973, joined Kodak as an engineer in an Applied Electronics research center. He took up the responsibility of inventing "hand-held electronic cameras" in 1974. The following year, the first prototype was born in the laboratory, and he became the "father of the digital camera".

The aim of this project is to take pictures without film, the prototype product is only 10,000 pixels, the image is very rough. When it comes to history, the game still remembers: "At that time, the digital technology is very difficult, CCD is difficult to control, A/D converter is difficult to make, digital storage media difficult to obtain, and the capacity is very small." There was no PC, playback equipment needed to be tailored. These difficulties took us 1 years to install the camera. ”

The digital camera was a small project for Kodak at the time, and because of the decision to use the digital method, there was not much moving machinery in the camera, and two technical engineers completed the project. In the selection of removable digital storage media, the game still hopes that the amount of storage can be similar to the number of 35mm film, so the final use of universal cassette tape, basically can store the equivalent of a film 30 photos. "A lot of the technology was very fresh at the time, the prototype circuit board can be opened, while filming, while adjusting." "It seems that the game is back in the lab.

"When the prototype was first presented to investors, they asked when the product could become a consumer product," I replied, and it was probably 15-20 years before the product went into the ordinary consumer family. "The judge is quite accurate, the development of digital camera is a long road, at the end of the 1970 to the early 80, Kodak Laboratories produced more than 1000 digital camera-related patents, laid a digital camera architecture and development base, so that digital camera step-by-step towards reality." 1989, Kodak finally launched the first commercial digital camera.
