CCD camera

A charge coupled device (CCD) camera is an apparatus which is designed to convert optical brightness into electrical amplitude signals using a plurality of CCDs, and then reproduce the image of a subject using the electric signals without time restriction. Charge coupled devices or CCDs are arrays of semiconductor gates formed on a substrate of an integrated circuit or chip. The gates of the CCD are operative to individually collect, store and transfer charge. When used in image applications, the charge collected and stored in each gate of the array represents a picture element or pixel of an image. The CCD image sensor includes an image sensing section, which performs photoelectric conversion, and a storage section, which is arranged separate from the image sensing section and temporarily stores charges acquired by the photoelectric conversion. A CCD camera includes a CCD imager IC (integrated circuit) and control circuits typically mounted on a printed wiring assembly. In CCD cameras, either a CCD matrix or one or more CCD lines is/are located in the focal plane behind the optical system. A CCD is normally used for the image pickup device of a digital camera. Image data captured by it is stored in a storage medium such as a compact flash memory or an IC memory card. To monitor the captured image, a display means such as an LCD (liquid crystal display) is generally equipped in the digital still camera. Charge coupled device (CCD) camera systems are configured to capture signals according to many different CCD output formats and pixel configurations.
