随着大规模集成电路技术的迅猛发展,信息技术已步入数字化时代。数字化技术是一次飞跃以数码相机为例,它将完全突破传统的暗房冲洗技术,不需要底片,无需暗房和药水。拍摄后只要通过电缆把相机与电脑连接起来,影像即可显示在屏幕上,如果满意即可立刻通过高精度彩色打印机打印出来,给人们带来全新的感觉。下面我们主要以电视为例,通过比较,看看数字化电视有哪些明显的优点。现在通用的电视是模拟电视,这种模拟电视技术极大地限制了图像信息在人们日常生活当中 With the rapid development of large-scale integrated circuit technology, information technology has entered the digital age. Digital technology is a leap to digital cameras, for example, it will completely break the traditional darkroom washing technology, no film, no darkroom and syrup. Just shoot the camera and the computer as long as the cable connection, the image can be displayed on the screen, if satisfied immediately by high-precision color printer to print, giving people a new feeling. Here we mainly to television as an example, by comparison, to see what are the obvious advantages of digital television. Now common television is analog TV, this analog TV technology greatly limits the image information in people’s daily life
