作者:大浪淘沙第一章 数码相机的综述 数码相机也叫数字式相机,是光、机、电一体化的产品。最早出现在美国,20多年前,美国曾利用它通过卫星向地面传送照片,后来数码摄影转为民用并不断拓展应用范围。数码相机的核心部件是电荷耦合器件(CCD)图像传感器,它使用一种高感光度的半导体材料制成,能把光线转变为电荷,通过模数转换器芯片转换成数字信号,数字信号经过压缩以后由相机内部的闪速存储器或内置硬盘卡保存,因而可以轻而易举地把数据传输给计算机,并借助于计算机的处理手段,根据需要和想象来修改图像。 数码相机的最大优势在于它的信息数字化,由于数字信息可以借助遍及全球的数字通讯网即时传送,所以数码相机首先可以实现图像的实时传递。...

一个绅士作者:[ 中] 程小青我在结婚以后,同佩芹作过一度环游东南名胜的新婚旅行,和霍桑隔离了好久。在这个当儿,霍桑虽单身独马,但他探案的任务仍继续不息,所以有许多案件,我都不曾亲身经历。这里所记的一篇就是他单独侦察的成绩之一。是他在事后告诉我的,故而记叙的体裁,也不能不变更一下子。一、掉换那位绅士模样的男子走到了远东旅社的转角,停了脚步,伸手在他的马褂袋中摸一摸,接着他的嘴唇微微地牵一牵,露出一种似笑非笑的表情。原来他的马褂袋中藏着一粒精圆的珍珠,足有黄豆般大,但是因着年代的关系,珠中所含的水分渐渐地枯涸,光泽便也暗淡了些。这粒珠子的价值,若和同样大小而光彩鲜艳的比较,自然也相差很远。...
