What is the difference between CCD and CMOS, two image sensors in digital cameras?

The difference between CCD and CMOS: different energy consumption and different characteristics.

First, different energy consumption:

CMOS usually consumes little energy, and the sensor embedded in CMOS is a low-power sensor.

The process of CCD consumes more energy, and the energy consumed by CCD is 100 times that of the same CMOS sensor.

Second, the characteristics are different:

CMOS chips can be manufactured on any standard silicon production line, so they are much cheaper than CCD sensors.

CCD sensor takes longer to put into mass production, so it is more mature. They have higher quality and more pixels.

App application

CCD is widely used in digital photography and astronomy, especially in high-speed photography such as optical telemetry, optical and spectral telescopes, and lucky imaging. CCD is widely used in video cameras, digital cameras and scanners, except that the camera adopts dot matrix CCD, that is, it includes X and Y directions for shooting plane images, while the scanner adopts linear CCD, and the scanning in X direction is only completed by the mechanical device of the scanner.
