Who invented the camera? 50-word composition

1975, in Kodak laboratory in Rochester, new york, USA, the black and white images of a child and a puppy were captured by CCD sensor and recorded on an audio tape. This is the first digital photo taken by the first digital camera in the world, and the development of the image industry has changed. Thirty years later, the inventor of the first digital camera came to China to look back on that period of history and look forward to the future of digital images with his keen insight. Steven Sasson joined Kodak after graduating from 1973 as an engineer in the applied electronics research center. 1974, he undertook the important task of inventing the "handheld electronic camera". The following year, the first prototype was born in the laboratory, and he became the "father of digital cameras". The purpose of this project is to shoot images without film. Its prototype product is only/kloc-0.0 million pixels, and its imaging is very rough. Speaking of that history, Cezanne still remembers it vividly: "At that time, digital technology was difficult, CCD was difficult to control, A/D converter was difficult to manufacture, digital storage media was difficult to obtain, and the capacity was very small. There was no PC at that time, and the playback equipment needed to be tailored. These difficulties took us 1 year to install this camera. " At that time, digital cameras were still a very small project for Kodak. Because of the decision to adopt digital method, there is not much moving machinery in the camera. Cezanne and two technical engineers completed the project. When choosing a removable digital storage medium, Cezanne hoped that its storage capacity would be similar to that of 35mm film, so he finally adopted a universal cassette recording tape, which can basically store 30 photos equivalent to a film. "At that time, many technologies were very new. The circuit board of this prototype can be tuned while shooting. " Cezanne seems to have returned to the laboratory. Growing up in the infancy of technology "When the prototype was first shown to investors, they asked when this product would become a consumer product, and I replied that it would take about 15 ~ 20 years for this product to enter the families of ordinary consumers." Cezanne's judgment is quite accurate. The development of digital cameras is a long road. From the end of 1970 to the beginning of 1980s, Kodak Lab produced more than 1000 patents related to digital cameras, which laid the foundation for the current architecture and development of digital cameras, and made digital cameras move towards display step by step.
