Therefore, the integrated circuit chip mainly optimizes the dynamic effect of the image and the brightness of the color.

Television principle:
Television uses electricity to transmit moving visual images instantly. Similar to movies, TV uses the visual residual effect of human eyes to display gradual still images frame by frame, forming visually moving images. The transmitter of the TV system converts every minute of the scene into electrical signals according to the brightness and chromaticity, and then transmits them in turn.
At the receiving end, the brightness and chromaticity of each detail are displayed according to the corresponding geometric position to reproduce the whole original image. Different countries scan TV signals in different ways from broadband channels. According to international radio consultative committee's suggestion, they are distinguished by Latin letters.
