Digital Cameras
The development of first monochrome then color CCDs also prompted development of electronic, still cameras. In the 1960s, NASA developed electronic imaging as a way of getting clearer pictures from space in preparation for the moon landing. During the 1970s, digital imaging was further developed for use with spy satellites.
Kodak first began to experiment with creating digital cameras in the mid-1970s, developing a crude engineering sample capable of capturing 100 x 100 pixel monochrome images that took 16 seconds to record onto a standard data audiocassette.
The first commercial electronic still camera was the original Sony Mavica, called the Pro Mavica, introduced in 1981 ,an analog electronic still camera that used a proprietary two-inch floppy disc to store images. Several other companies announced similar electronic still cameras, but these cameras were either too expensive or their images of insufficient resolution ?often both ?to crack the consumer market.
In the mid-1980s, several camera makers introduced multi-thousand dollar electronic still cameras for the professional market including Canon with its RC-701 and Nikon with its QC-1000C. In mid-1987, Sony unveiled a consumer version of its Mavica, the MVC-C1 Hi Band VF Mavica, an analog still camera, not digital, that stored images on two-inch square discs. In September 1988, Fuji unveiled the DS-1P, the first electronic still camera that recorded images digitally on a 16MB internal memory card developed with Toshiba. But the DS-1P was never sold in the U.S.
In 1991, Kodak packed a 1.3 megapixel CCD onto a Nikon film camera body. The resulting Kodak DCS (Digital Camera System) 100 is often cited as the first true commercially available digital camera, but it was sold only to well-heeled photojournalists for $20,000.
Electronic camera makers assumed their eventual consumer cameras would be connected to TV sets to create slide shows, not connected to computers. That assumption changed in 1987 when Letraset introduced Image Studio, the first image manipulation software. But Image Studio was designed only for the Apple Macintosh and handled only grayscale images. In 1990, Adobe released the first version of its now-standard photo manipulation software, PhotoShop, which handled color images. But in many ways, both Image Studio and PhotoShop were applications in search of hardware.
Kodak saw the consumer commercial possibilities of a film less digital camera connected to a computer and began working with Apple on a consumer-ready version. On February 17, 1994, the Kodak-designed Apple QuickTake 100 was introduced at the Tokyo MacWorld Expo. The QuickTake 100 looked more like a fancy pair of binoculars. It ran on three AA batteries and could store eight 640 x 480 images in its internal solid-state memory or could be connected to a PC via a serial port connection. The Apple QuickTake 100 went on sale in the U.S. in May 1994 (for Macintosh only; the Windows version arrived a month later) for less than $1000, making it the first true consumer digital camera. Kodak followed with its own version, the DC-40, that same spring.
Advances in digital still cameras came fast and furious. In July 1995, Casio\'s QV-10 was the first digital camera equipped with an LCD screen along with a viewfinder. Kodak\'s DC-25 was the first digital camera to use removable Compact Flash in 1996. The first million (or mega) pixel models arrived in 1997, and each succeeding year has seen nearly a million pixel increase in resolution, along with USB connectivity and a variety of removable storage media options. In 2002, cell phones equipped with digital cameras began appearing, phones with megapixel CCDs in 2004, the same year several consumer digital camera makers unveiled 8 megapixel models for less than $1000.
第一台商用数码相机诞生于1981年的SONY，难道一直到1987年，经过6年的发展中国竟然没有一台数码相机？？即使不对中国出口，也有到外国的中国人带回这新鲜玩意吧。自己犯了错误要勇于承认，重要的是态度，不需要太多的狡辩。另外，中国当时有没有数码相机，不是通过在这儿调查就能得出结果的
