CCD and CMOS

CCD

A CCD (charge-coupled device) is a device that transfers electricity. In other words, convert them to digital values. It is a device that converts digital signals to digital values.

CMOS

Complementary meta-oxide-semiconductor is a technology that guides chips to form very high-quality ICs (integrated circuits). More performance than CMOS image CCD images. Smartphones used to use only CCD sensors, while modern smartphones use more expensive and sophisticated CMOS sensors.
