1.引言在我们周围,存在着许许多多各色各样光的信息。人的眼睛可以接收分布在空间的这些光的信息一图像,传给大脑,用以控制自身的行动或进行判断。而摄像器件正好是与人眼具有同样功能的一种输入器件,它可以检测这种光学信息,并把它转换成电信号输出。现在,摄像器件已被广泛应用于图像远距离传输(电视、传真等)和具有图像信息判断功能的自动化机器等方面。 1. Introduction Around us, there are many different kinds of light information. The human eye can receive an image of the light distributed in space and send it to the brain to control its own actions or to make judgments. An imaging device, on the other hand, is an input device that has the same function as the human eye and can detect such optical information and convert it to electrical signal output. Now, camera devices have been widely used in image transmission over long distances (television, fax, etc.) and automated machines with image information determination capabilities.
