What kind of camera is CMOS?
In today's digital photography field, CMOS cameras have become one of the mainstream technologies. Whether it is a smartphone, a professional SLR, or a surveillance device, CMOS sensors play an important role. This article will introduce in detail the principles, advantages and recent hot topics of CMOS cameras to help readers fully understand this technology.
1. Definition and principle of CMOS camera
CMOS (Complementary Metal-Oxide-Semiconductor) is an image sensor technology. Compared with traditional CCD (charge-coupled device) sensors, CMOS sensors convert optical signals into electrical signals through independent signal conversion circuits for each pixel, thereby capturing images.
2. Comparison between CMOS and CCD
| Comparative item | CMOS | CCD |
|---|---|---|
| Power consumption | low | high |
| cost | lower | higher |
| Response speed | Fast | slow |
| Image quality | medium | high |
3. Advantages of CMOS cameras
1.Low power consumption: CMOS sensors consume much less power than CCD, making them ideal for mobile devices.
2.High integration: CMOS technology can integrate sensors and processing circuits on the same chip to reduce costs.
3.Quick response: CMOS sensor has faster reading speed and is suitable for high-speed continuous shooting and video recording.
