Digital camera is a product integrating optics, machinery and electronics. It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access mode of BenQ digital camera C850, interactive processing with computer, real-time shooting and so on.

Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element, 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. The characteristic of imaging element is 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. Later, digital photography was converted to civilian use, and its application scope continued to expand.
