有人说,21世纪是数字的时代。的确,随着科学技术的飞速发展,人类已经开始进入数字的时代。不论工作中,还是在生活中都会跟数字技术打交道。数码相机(亦称数字相机)是未来相机的发展趋势。它有别于通过传统光学成相的相机,无须胶卷与冲洗,而把捕捉的图像以数字形式存储器替代感光材料,再通过液晶显示屏既拍既现,亦可随时擦除。也可通过专用电缆连接到一种特殊的打印机上,即可打印出色彩鲜艳的照片来。还可以与计算机RS-232串行口相连,运用图形处理如PHOTOSHOP等软件对图像进行任意处理,可充分体现作者的丰富想象力。从原理上讲,数码相机依赖于电荷耦合设备(CCD)而非银色的卤化物来捕获图像。CCD拥有一个
Some people say that the 21st century is the era of numbers. Indeed, with the rapid development of science and technology, mankind has begun to enter the digital era. Whether at work, or in life will be dealing with digital technology. Digital camera (also known as digital camera) is the future trend of the camera. It is different from the traditional optical phase camera, without the film and flushing, and the captured image to digital form memory instead of photosensitive material, and then both through the LCD screen both present, can also be erased at any time. You can also print colorful photos by connecting them to a special printer via a dedicated cable. Can also be connected with the computer RS-232 serial port, the use of graphic processing software such as PHOTOSHOP arbitrary treatment of images, can fully reflect the author’s rich imagination. In principle, digital cameras rely on charge-coupled devices (CCDs) instead of silver halides to capture images. CCD has one
