A light sensitive chip used for image gathering. In their normal condition these are greyscale devices. To create color a color pattern is laid down on the sensor pixels, using RGBG color mask. (Red, Green, Blue, and Green) The extra Green is used to create contrast in the image. The CCD Pixels gather the color from the light and pass it to the shift register for storage. CCD are analog sensors, the digitizing happens when the electrons are passed through the A to D converter. The A to D converter converts the analog signal to a digital file or signal.

An image sensor which is a large scale integrated circuit containing hundreds of thousands of photo-sites (pixels) which convert energy to electronic signals.

An imaging device consisting of a large-scale integrated circuit which has a two-dimensional array of hundreds of thousands of charge-isolated wells, each representing a pixel.

a device that takes input light or electric charge and converts the intensity of the input into an output electronic signal. Charged coupled devices are designed as a group of pixels, where each pixel will trap electrons in proportion to the input stimuli. Each pixel may be read in sequence to determine the input stimuli level. Charged coupled devices are widely used in scientific instruments and digital cameras to capture images. Charged coupled devices are however more difficult to make than more common processes such as CMOS, although they do have better imaging performance. Due to easier fabrication, CMOS sensors are making inroads into traditional charged coupled device applications in the low-end, and CMOS sensor quality is rapidly improving as well.

A semiconductor device that can produce an electrical output analogous to the amount of light striking each of its elements. CCD sensors are used in both motion video and still video cameras.
