现在,人们广泛使用信息化时代这个字眼,但对其具体含意,恐怕尚未确切了解。不过可以预想到,图像信息的转换、传输、记录、处理、显示等技术及其装置作为今后信息领域的核心技术,将得到很好的发展。其中摄像装置由于占据主要的转换部分,所以在信息化时代的所有系统中是不可缺少的一环。通过摄像装置要把光学图像转换为电信号,就必须具备以下四种功能:
Now, people widely use the word era of information, but its specific meaning, I am afraid that is not yet an exact understanding. However, it can be foreseen that technologies and devices for converting, transmitting, recording, processing, and displaying image information will be well developed as core technologies in the field of information in the future. Among them, the camera device occupies a major part of the conversion, so it is an indispensable part of all systems in the information age. Through the camera device to convert optical images to electrical signals, it must have the following four functions:
