How Digital Cameras Work
- Jul 10, 2018 -

Digital cameras are products that integrate optical, mechanical and electronic integration. It integrates the conversion, storage and transmission of image information, with digital access mode, interactive processing with the computer and real-time shooting. Light enters the camera through the lens or lens group, and is converted into a digital signal by the digital camera imaging component, and the digital signal is stored in the storage device through the image computing chip. The imaging component of a digital camera is CCD or CMOS. The imaging component is characterized by the fact that when light passes, it can be converted into an electrical signal according to the light. Digital cameras first appeared in the United States. More than 20 years ago, the United States used it to transmit photos to the ground through satellites. Later, digital photography was turned into civilian use and continued to expand its application.

Divided by purpose: SLR camera, micro single camera, card camera, telephoto camera and home camera. Digital cameras differ from conventional cameras in that the image is recorded on the film by chemical changes in silver bromide, which is a photo-induced charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). Before the image is transferred to a computer, it is usually stored in a digital storage device (usually using flash memory; floppy disks and rewritable discs (CD-RW) are rarely used in digital camera devices).
