An active-pixel sensor is an image sensor where each pixel sensor unit cell has a photodetector and one or more active transistors. In a metal–oxide–semiconductor active-pixel sensor, MOS field-effect transistors are used as amplifiers.

Is CMOS sensor good?

CMOS sensors traditionally have lower quality, lower resolution and lower sensitivity. CMOS sensors are just now improving to the point where they reach near parity with CCD devices in some applications. CMOS cameras are usually less expensive and have great battery life.

What does CMOS stand for in CMOS sensor?

Like CCDs, CMOS(Complementary Metal Oxide Semiconductor) sensors are semiconductor image sensors that convert light into electrical signals. CMOS sensors are semiconductor light sensors like CCDs.
