Complementary Metal-Oxide-Semiconductor sensor technology dominating modern digital cinema cameras.
Definition
CMOS (Complementary Metal-Oxide-Semiconductor) is the predominant sensor technology in digital cameras. Unlike CCD sensors, CMOS allows for the integration of amplifiers directly onto the chip, enabling faster readout, lower power consumption, and higher resolutions.
Practical Application
Virtually all modern cinema cameras utilize CMOS: ARRI ALEXA, RED, Sony Venice, Canon C500, Blackmagic. The technology enables features like Dual Native ISO, High Frame Rates, and 8K resolution, which would be impossible with CCD.
Technical Details
CMOS sensors read out line by line (Rolling Shutter), which can lead to distortions with fast movements. High-end cameras like the ARRI ALEXA 35 minimize this effect through rapid readout. Some cameras offer Global Shutter CMOS for distortion-free recording.
