English term or phrase:photosite
In modern digital cameras, the image forms on a charge-coupled device that contains an array of photosites, each of which converts light into electricity. Each photosite—regardless of the color of the color filter array above it—maps to a conventional, full-color, red-green-blue pixel. Algorithms sample the array of photosites to produce a signal that fits a different array—that of the display. The success of the translation depends on the sampling rate.
Explanation: Unlike traditional cameras that use film to capture an image, digital cameras use a image sensor called a CCD. These sensors contain millions of photosensitive diodes called photosites. When the shutter opens, each photosite records the intensity or brightness of the light that falls onto it by accumulating a charge; the more light, the higher the charge. The brightness recorded by each photosite is then stored as a set of numbers that can then be used to set the colour and brightness of dots on the screen or ink on the printed page to reconstruct the image.
