Definition: electronic sensor used by all autofocus cameras, capable of detecting subject contrast.
Definition: Charged Coupled Device, a light sensitive chip used for image gathering. In their normal condition these are grayscale devices. To create a colour pattern is laid down on the sensor pixels, using RGBG colour mask. (Red, Green, Blue, and Green) The extra Green is used to create contrast in the image. The CCD Pixels gather the colour 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. Area CCD:A square or rectangular CCD that can capture an entire image at once, which is essential for dynamic subjects and flash photography. Linear CCD: Scanner-type CCD, these sensors are long and thin, and capture an image by recording a vast number of individual "exposures" while scanning across the picture frame. These are best suited for still subjects and continuous illumination.
Definition: Charge Coupled Device: one of the two main types of image sensors used in digital cameras. When a picture is taken, the CCD is struck by light coming through the camera's lens. Each of the thousands or millions of tiny pixels that make up the CCD convert this light into electrons. The number of electrons, usually described as the pixel's accumulated charge, is measured, then converted to a digital value. This last step occurs outside the CCD, in a camera component called an analog-to-digital converter.
