What are the categories of cameras?

Cameras are divided into SLR cameras, mirrorless cameras, compact cameras, telephoto cameras and home cameras. Digital cameras are different from ordinary cameras in that they rely on the chemical change of silver bromide to record images on film. The sensor of a digital camera is a light-sensitive charge-coupled device or a complementary metal oxide semiconductor.

1. Cameras are divided into SLR cameras, mirrorless cameras, compact cameras, telephoto cameras and home cameras. Digital cameras are different from ordinary cameras in that they rely on the chemical change of silver bromide to record images on film. The sensor of a digital camera is a light-sensitive charge-coupled device (CCD) or a complementary metal oxide semiconductor (CMOS). Images are usually stored on a digital storage device (often using flash memory; floppy disks and compact discs rewritable (CD-RW) are rarely used in digital camera equipment) before being transferred to the computer.

2. Digital cameras are optical, mechanical, and electronic products. It integrates components such as conversion, storage and transmission of image information, and has the characteristics of digital access mode, interactive processing with computers and real-time shooting. Light enters the camera through the lens or lens group, and is converted into digital signals through the digital camera imaging element. The digital signals are stored in the storage device through the image computing chip. The imaging element of a digital camera is CCD or CMOS. The characteristic of this imaging element is that when light passes through, it can be converted into electronic signals according to the difference in light. Digital cameras first appeared in the United States. More than 20 years ago, the United States used them to transmit photos to the ground through satellites. Later, digital photography was converted to civilian use and its application scope continued to expand.
