Why use CMOS Image Sensor?
CMOS, or Complementary Metal Oxide Semiconductor, also contains millions of photosites. The primary difference is that CMOS image sensors have several transistors at each pixel that amplify and move the charge using wires. This approach allows each pixel to be read individually, however it also allows for more distortion. The major advantage of CMOS Image sensor is that it consumes 10 times lesser power than the equivalent CCD. CMOS image sensors can be fit into smaller, more portable digital cameras and also are less expensive.
