CMOS VS 3CCD

CCD stands for charge-coupled device;
CMOS stands for complimentary metal-oxide semiconductor.
These are the chips onto which the light captured by a camcorder's lens is focused. Those signals are processed further inside the camcorder and ultimately, the image is recorded to the camcorder's storage medium, whether it's tape, DVD, or an internal or external hard drive. with multiple image sensors use one chip per light primary color (red, green and blue), and utilize a separate image processor to combine the three signals into a color video image. Newer and cheaper CMOS chips bundle both an image sensor and image processor into a single chip. All CCD designs utilize an image processor that is separate from the actual light-capturing sensor.
