Cameras are divided into which categories

Cameras are categorized into DSLRs, microsingle cameras, card cameras, telephoto cameras and home cameras. Digital cameras and ordinary cameras on film by the chemical change of silver bromide to record images of different principles, digital camera sensor is a light-sensitive charge-coupled device or complementary metal oxide semiconductor.

1. Cameras are categorized as DSLRs, microsingle cameras, card cameras, telephoto cameras, and home cameras. Digital cameras and ordinary cameras on film by the chemical change of silver bromide to record images of different principles, digital camera sensor is a light-sensing charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS). The images are usually stored in a digital storage device (usually using flash memory; floppy disks and rewritable compact disks (CD-RWs) are rarely used in digital camera equipment) before being transferred to a computer.

2. The digital camera is an integrated optical, mechanical, and electronic product. It integrates the conversion of image information, storage and transmission components, with digital access mode, interactive processing with computers and real-time shooting and other characteristics. Light enters the camera through the lens or lens group, and is converted into digital signals by the imaging element of the digital camera, and the digital signals are stored in the storage device through the image computing chip. The imaging element of a digital camera is a CCD or CMOS, and the imaging element is characterized by its ability to convert light into electronic signals when it passes through, depending on the light. Digital cameras first appeared in the United States, more than 20 years ago, the United States had used it to transmit photos to the ground via satellite, and then digital photography to civilian use and continue to expand the scope of application.
