Today I want to know a little about digital camera, so I searched a lot of information on the internet, and I found there was a very long long history of digital camera development.
Since the French people produced the first camera, had already passed nearly 200 years of development. During these 200 years, camera has undergone dramatic changes in people’s life. Most 21st century cameras are digital (Battles, L, 2012). Introduction of digital camera marks a new area of electronic development, and also people’s life would be changed by high technology.
Steven Sasson, an engineer at Kodak, built the first digital camera (Pic 1) in 1970. It took 23 seconds to record the digitized image to the cassette, and people need to remove the cassette and place it in a custom playback device to browse the photographs. According to Steve, S (2007), it was a camera that did not use any film to capture still images – a camera that would capture images using a CCD imager and digitize the capture scene and store the digital info on a standard cassette. Although the camera was big and looks difficult to carry on but it was not required any capture and printer that people can view the shots.
In later years, the first commercial CCD (charge-couple device) camera was produced by Fairchild in 1976. And in following year Konica introduced the C35-AF, which was the first compact point and shoot autofocus camera.
In fact, in 1973, Sony formally began their own research work called ‘CCD’, and on the basis of technology development in 1981, a new era in photography began on August 25, 1981 when unveiled a prototype of the global first still video camera, the Mavica (Magnetic Video Camera) (Pic 3). Mavica used removable disks as the main recording media, and this camera is positioned as the “pioneer of the digital era”, and also for the first time, the light signal for the camera was changed to electronic signal transmission.
Other companies were closely followed by the Panasonic, COPAL, FUJI, Canon, and Nikon. They began the research work of digital camera and then introduced their prototype electronic camera during 1984 to 1986. There are some analogue cameras which may have been the start of the digital camera, such as Canon RC-701 in 1984, Panasonic prototype electronic camera in 1984, FUJI ES-1 still video camera, and KONICA SVC-40 prototype still video camera.
In 1987, Casio VS-101 was the first marketed MOS (metal oxide semiconductor) still video camera. Although it just has 280k pixels CCD, it was the very important meaning of the DC industry. Then in 1988, Canon produced RC-760 (Pic 5), which was 6 million pixels; this is the first camera with 6 million pixels because in the beginning of development of digital camera, it was very difficult to achieve the high pixels. Canon RC-760 uses a 2-inch video floppy disk capable of recording 50 or 25 images.
As the rise of the digital camera, the first true digital handheld camera was developed by FUJI DS-1P in 1988, but it never sold. The first digital camera to actually go on sale was in 1990, Dycam Model 1 (Pic 6) by Logitech FotoMan. It was fully digital but not analog like Sony Mavica. It could attach to a PC or Macintosh and produce black and white photos at 320 by 24 resolution (Camera Cruiosities, 2012).
Over the next years, the cameras connection and CompactFlash had improved. In 1994 the Olympus Deltis VC-1100 became the world’s first digital camera with built in transmission capabilities. And the Kodak DC-25 (Pic 7) in the same year was the first camera to use CompactFlash card, according to camera hacker (2005), CompactFlash is the de facto standard to flash memory storage, and it is used everywhere from digital cameras to MP3 players to embedded systems. In addition, the first camera with removable PC card was Nikon COOLPIX 100 (Pic 7).
Casio QV-10 in 1995, which was the first with an LCD screen on the back. The screen measured 46mm (1.8 inches) from corner to corner. It was also the first consumer digital camera with a pivoting lens. In 1995, Nikon and FUJI launched a totally new deign called E2/E2s, it was no longer just copy from the traditional camera style, but used the integration design, and thus easily can let people feel fresh, but this digital camera’s resolution only 1.3 million pixels. However, 4 years later, Nikon produced the D1, with the far lower price than the Kodak DCS start a new era of digital camera to a populace accustomed style. In 1999, Sony marketed the MVC-FD5 and MVC-FD7, the first ever-digital cameras using a standard floppy disc as the storage medium. These cameras proved to be very popular at that time. After year 2000, digital cameras had a great improvement, Sony donated first 4 MP consumer digital camera, which was lens f2.0-2.5, 34-102 mm, shutter 8 sec to 1/1000sec. In order to surpass Nikon, Canon announced a digital camera, which is aimed fast shooting, called EOS 1D (Pic 8); this camera was better than Nikon D1 in speed and technical as a whole. In 2002, Sony produced MVC-CD400 with mini disk, digital camera became easier to carry and record. Canon also had new production called EOS 30D in 2006, and it can was 3504 * 2336 pixels.
Nevertheless, digital camera was unable afforded by ordinary people because the high price, although it was powerful at shooting. So in August 2003, Canon introduced the EOS 300D (Pic 9) that with plastic material, it also used the CMOS which EOS 10D used, and lower than $1,000. So Canon changed the competition for whole digital camera market.
The digital camera today is getting more popular because they are indeed easy and convenience to use and offer a host of amazing shooting. Digital cameras plug in to PC via USB so people can upload photos very easily and quickly, and with the software development, editing and printing are becoming easier than before as well. Digital cameras make it simple to share pictures both online and in print, and also let people can record their real life more efficient.
