Definition – What does CCD (Charged Coupled Device) mean?
Charged Coupled Device (CCD) is a sensor that is used in digital cameras to record still and moving images. It captures light and converts it to the digital data that is recorded by the digital camera. For this reason, a Charged Coupled Device is often considered the digital version of the film. The excellence of the image depends on the resolution of the sensor. In digital cameras, the resolution is calculated in Megapixels (MP). Therefore, an 8MP camera can capture twice as much information as the 4MP camera. The result is a greater image with more details.
Glossary Web explains CCD (Charged Coupled Device)
Usually Charged Coupled Device in video cameras are calculated by physical size. For example, most digital cameras use a CCD around 1/6 or 1/5 of an inch in size. Expensive cameras may have CCDs 1/3 of an inch in size. The larger the sensor, take more light it can capture that means it will produce better quality video in low light settings. All the professional video cameras often have three sensors that are referred to as 3CCD that use separate CCDs for capturing red, green, and blue hues.
