Huygens Remote Manager - Help: Size of the unitary CCD captor
The size of the ccd captor elements is a property of the camera used.
The image sensor employed by most digital cameras is a charge coupled device (CCD). The CCD is a collection of tiny light-sensitive diodes, which convert photons (light) into electrons (electrical charge). These diodes are called photosites. Each photosite is sensitive to light — the brighter the light that hits a single photosite, the greater the electrical charge that will accumulate at that site.
