The image intensifier TV system camera and imaging are two basic links of video transmission in image intensifier television system c arm intensifier. Camera mainly converts image into TV signal, while imaging converts TV signal into optical image.
The brightness of each point in the image varies with time. A complete picture can be seen as composed of many small cells of the same shape and size, each of which is a pixel. Obviously, the more pixels in the picture, the clearer the image will be.
To capture and display a complete image, an electron beam is usually used to bombard the pixels one by one from left to right and from top to bottom. The process of electron beams bombarding pixels back and forth is called scanning. Among them, left-to-right scanning is called row scanning, while top-down scanning is called frame scanning.
