　We Are Living a Digital Life　数码生活进行时

     1　认识数码相机
     A digital camera is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor. Most 21st century cameras are digital.
     Front and back of Canon PowerShot A95 Digital cameras can do things film cameras cannot：displaying images on a screen immediately after they are recorded, storing thousands of images on a single small memory device, and deleting images to free storage space. The majority, including most compact cameras, can record moving video with sound as well as still photographs. Some can crop and stitch pictures and perform other elementary image editing. Some have a GPS receiver built in, and can produce Geotagged photographs.
     The optical system works the same as in film cameras, typically using a lens with a variable diaphragm to focus light onto an image pickup device. The diaphragm and shutter admit the correct amount of light to the imager, just as with film but the image pickup device is electronic rather than chemical. Most digicams, apart from camera phones and a few specialized types, have a standard tripod screw.
     Digital cameras are incorporated into many devices ranging from PDAs and mobile phones (called camera phones) to vehicles. The Hubble Space Telescope and other astronomical devices are essentially specialized digital cameras.
     Digital cameras are made in a wide range of sizes, prices and capabilities. The majority are camera phones, operated as a mobile application through the cellphone menu. Professional photographers and many amateurs use larger, more expensive digital single-lens reflex cameras (DSLR) for their greater versatility. Between these extremes lie digital compact cameras and bridge digital cameras that "bridge" the gap between amateur and professional cameras. Specialized cameras including multispectral imaging equipment and astrographs continue to serve the scientific, military, medical and other special purposes for which digital photography was invented.
     2　数码产品的表达方式
     digital watch　数字手表
     A digital display simply shows the time as a number, e.g., 12:08 instead of a short hand pointing towards the number 12 and a long hand 8/60 of the way round the dial.
     digital camera　数码相机
     A digital camera is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
     digital video　数码录像
     Digital video is a type of video recording system that works by using a digital rather than an analog video signal.
     Digital television　数字电视
     Digital television (DTV) is the transmission of audio and video by digital signals, in contrast to the analog signals used by analog TV. Many countries are replacing over-the-air broadcast analog television with digital television to allow other uses of the radio spectrum formerly used for analog TV broadcast.
     MP3　随身听
     It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
     USB flash drive　优盘
     USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk.
     数码技术又被称为数字技术，因为其核心内容就是把一系列连续的信息数字化或者说是不连续化。数码产品一般指的是MP3、U盘，数码照相机/摄像机......可以通过数字和编码进行操作的机器并且可以与电脑连接的，都称为数码产品。电视/电脑 /通讯器材/移动或者便携的电子工具等， 在相当程度上都采用了数字化。
