Classification and comparison of camera
The main working principle of the camera is Samples the points on the image in an interlaced manner at a certain resolution. When scanning to a point, through the image sensor chip at the point of the image of the gray scale into a gray-to-one correspondence with the voltage value And then the voltage value through the video signal output. Specifically, the camera continuously scans a line on the image to output a continuous voltage and video signal, the voltage signal is reflected in the ups and downs of the line image of the gray-scale changes in the situation.
