What is an image sensor?

Image sensors are electronic devices that convert light into electrical signals to create digital images. They are commonly found in cameras, smartphones, medical imaging equipment, and other devices that capture visual information. The two main types are CCD (Charge-Coupled Device) and CMOS (Complementary Metal-Oxide-Semiconductor) sensors, each with unique characteristics and applications. Image sensors play a crucial role in determining the quality and resolution of digital images. Their performance impacts everything from photo clarity to low-light capabilities.
