1997年,电脑更进一步走入中国家庭的同时,数字式照相机也开始敲门。本人在东京从事多年的电脑工作,在这里愿将数字式照相机基本原理和存储方式向祖国的读者作一介绍。 数字式照相机的原理是利用CCD (Charge Coupied Device)使光信号转变为电信号、记录在存储器上。CCD的决定性的指标在于它的像素数。受光像素数越多,图像的清晰度越高。中档次的数字式照相机 In 1997, as computers went further into Chinese families, digital cameras began to knock on the door. I am in Tokyo for many years engaged in computer work, here is willing to digital camera basic principles and storage methods to the readers of the motherland to make an introduction. Digital camera’s principle is the use of CCD (Charge Coupied Device) so that optical signals into electrical signals, recorded in the memory. The decisive indicator of a CCD is its number of pixels. The more light pixels, the higher the image clarity. Mid-range digital camera
