![]() All CCD designs utilize an image processor that is separate from the actual light-capturing sensor. Newer and cheaper CMOS chips bundle both an image sensor and image processor into a single chip. Cameras 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. 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. ![]() These are the chips onto which the light captured by a camcorder’s lens is focused. ![]() Videography is film cinematography’s younger brother, and understanding the role that light plays in videography, is the key to understanding the difference between CCDs and CMOS technology.ĬCD stands for charge-coupled device CMOS stands for complimentary metal-oxide semiconductor. Eventually, by the 1960s and 70s, they began to capitalize on this, occasionally shooting right into the lights on their sets, which became a trademark for directors such as Stanley Kubrick and Steven Spielberg. The great film directors know that they’re really not in the business of photographing actors-they’re in the business of recording light.
