Introduction to Image Sensors

The image sensor is an important component of a digital camera and can be divided into CCD and CMOS based on the element.

CCD (Charge Coupled Device, charge-coupled device) is a high-end technical element used in photography and videography. CMOS (Complementary Metal-Oxide Semiconductor, complementary metal-oxide semiconductor) is applied in products with lower image quality. Its advantage is that the manufacturing cost is lower than that of CCD, and it also consumes much less power. This is also the reason why many products in the market that use USB interfaces do not require external power sources and are inexpensive.
