Q: What does CCD mean?A: CCD is an acronym for Charge-Coupled Device. It is the image sensor that separates the spectrum of color into red, green and blue for digital processing by the camera. In digital cameras both Area and Linear CCDs are used. A CCD captures only black-and-white images. The image is passed through red, green and blue filters in order to capture color.
Area CCD is a square or rectangular CCD that can capture an entire image at once, which is essential for dynamic subjects and flash photography.
Linear CCD, also known as scanner-type CCD, is a sensor that is long and thin. They 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.
