Question 4: Who invented the first digital camera in the world?
Kodak developed the world's first digital camera in 1975.
Background information and technical data:
Developer: Kodak Applied Electronics Research Center
Prototype Name: "Handheld Electronic Camera"
Dimensions: 8.25 inches wide, 6 inches thick and 8.9 inches high (20.9x 15.2x 22.5 cm).
Weight: 8.5 lbs (3.9 kg)
Power supply: 16 AA batteries
Digital memory: 4 farads, 152 bits.
Image sensor: Fairchild 20 1 100 CCD array.
Tape recorder: Memodyne low-power digital tape recorder.
Storage device: standard 300-foot Philips digital tape
Performance characteristics:
The exposure time is 50 milliseconds.
Recording image: 23 seconds
Recording density: 423 bits/inch
Image capacity: each tape can store 30 photos.
Control logic: CMOS integrated circuit
1974 original summary of the project:
"Make a hand-held camera without film, shoot black-and-white still images electronically, and then record them with a cheap audio-grade tape player. The tape drive should be removable from the camera and plugged into the playback device for viewing on the TV.
Technical operation:
The camera takes images through a CCD with 10000 pixels (arranged in an array of 100 x 100). Each pixel occupies 4 bits-a four-digit combination of 0 and 1, representing each point in the photo. Once the shooting is completed, the image will be digitized and stored in the camera's buffer memory. From here, photos can be recorded in a more permanent memory, so that they can be taken out of the camera and played. Cassette tape recorders are used for this purpose. It takes about 23 seconds for the camera to write the image to the tape drive from the exposure.
Question 5: Who is the inventor of digital camera? Historical Records of the Development of Digital Cameras
2005.07.28 1 1:27:08
The camera has been developed for nearly 200 years since it was invented by the French in 1839. In these 200 years, the camera has experienced the trinity from black and white to color, from simple optical mechanical structure to optical mechanical electronics, from traditional silver salt film to digital memory as a recording medium today. Laughing at the floating clouds obscures the eyes, and the sea changes suddenly. The appearance of digital cameras officially marks the leap-forward development of the camera industry into a brand-new digital era, and people's image life has been completely changed.
Since Bauer and Smith of Bell Institute announced the invention of "CCD" on 1969 and 10 on June 7th, this photosensitive element has been further improved and has been widely used today. The latest improved versions, such as 4-color CCD and super CCD, are constantly emerging, and the number of pixels has already exceeded 10 million pixels, but the imaging effect has also reached perfection.
After more than ten years of continuous development, DC industry has gone out of the initial stage, with more mature design and increasingly powerful operation functions, and with the further reduction of manufacturing costs, the development of such products has shown signs of development.
Generally speaking, the development process of DC industry for more than ten years has been adhering to the development vein of "higher, faster, stronger and more humane". It is with the unremitting efforts of manufacturers that today's digital camera market will become so prosperous and beautiful. While enjoying the convenience brought by technology, people can't help but think of the bumpy road that digital cameras took at the beginning of their birth. Some classic models that have had a great impact on this industry are still unforgettable.
Cambrian Explosion
A lot of life suddenly appeared in CAMBRIAN, and the whole earth became colorful and full of vitality overnight. Archaeologists haven't given a clear answer yet. The 1980s is no different from the Cambrian of digital camera industry. In less than ten years, digital cameras quickly got rid of infancy and gradually learned to stumble. Although the resolution was still very low at that time, the participation of many manufacturers made the industry full of vitality.
Sony ma bika- the world's first electronic camera without photographic film
In June, 1973, 1 1, Sony officially started the research of "electronic eye" CCD. On the basis of continuous technical accumulation, the world's first electronic camera-still image "Mapika" was launched in June of 438+098 1. The camera uses 10 mm× 12 mm CCD chip, and the resolution is only 570× 490 (279,000) pixels, which is the first time to convert optical signals into electrical signals for transmission.
Then, Panasonic, Copa, Fuji, Canon, Nikon and other companies also started the research and development of electronic cameras, and launched their own prototype electronic cameras at 1984- 1986, and the explosion of life began.
Sony MYC-A7AF-Digital camera has a purely physical operation mode for the first time.
The second camera is also made by Sony, which is a milestone in the development history of DC industry. It can be seen that the company's market position today is by no means "a wave of fame". 1986, Sony released MYC-A7AF, which made the digital camera have a purely physical operation mode for the first time. It can record still images on a 2-inch optical disc, and the pixel resolution has been extended to 380,000 pixels. Casio VS- 10 1―― The first CMOS sensor electronic camera
1987, Casio first sold VS-10/electronic cameras using CMOS photosensitive devices in the market. Although the resolution can only reach 280 thousand pixels, it is of great significance to DC industry.
As far as today is concerned, the dispute between the orthodox CMOS and CCD of digital camera photosensitive devices has long been settled. In addition to being widely used in Canon's high-end cameras today, other manufacturers regard CCD as the leading direction of their products. It is true that CMOS has the advantages of full format and low energy consumption, which is really attractive, but the shortcomings of low dynamic range can not help but make people "stay away from it."
Canon RC-760- the first 600,000 pixel model
In order to get the shooting effect close to the traditional camera, improving the resolution of CCD pixels is the most fundamental solution, but in the early days of the birth of digital cameras, we wanted to improve the pixel level. & gt
