Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element of a digital camera, and the digital signal is stored in a storage device through an image operation chip. The imaging element of digital camera is CCD or CMOS, which is characterized in that when light passes through it, it can be converted into electrical signals according to different light. Digital cameras first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite.
