What is the most common light-sensitive imaging surface on a video camera that splits light into red, green, and blue?

• A. CMOS
• B. Sensor
• C. Image Sensor
• D. CCD

Answer: (D)

The key idea is that color video is captured by a light-sensitive surface that converts photons into an electrical signal, with a color filter layered on top to separate light into red, green, and blue components. The most common surface for this in many video cameras, especially historically, is the CCD sensor. It works by collecting photon-generated charges at each pixel, then moving those charges to a readout area for conversion to voltage. A color filter array sits over the sensor so each pixel responds to a specific color (red, green, or blue); the camera then reconstructs a full-color image from those color-segregated signals. While another popular sensor type exists today and is widely used, the CCD has long been the standard imaging surface for color video capture due to its low noise and high image quality advantages.
