CCD - Photosensitive CCDs are used in scanners, digital cameras, and video cameras. The CCD basically reads the image by storing a group of charges based on the image to which it is exposed. These charges are analog charges, as opposed to simple digital on/off charges. Thus, you can grab degrees of light and color to transfer a visual image into a group of electrical charges, and then to your computer screen, video tape, or printer. |
