Abstract
A Charge-Coupled Device (CCD) image sensor includes a linear array of photodetectors. The photodetectors in the linear array are arranged into distinct sub-arrays with each sub-array including two or more photodetectors. An output channel is connected to each sub-array of photodetectors. Each output channel includes a horizontal CCD shift register and an output structure connected to an end of the horizontal CCD shift register in a linear arrangement with respect to each other. Each successive output channel is disposed on an alternate side of the linear array. Every other output channel is disposed on an alternate side of the linear array. One or more dark reference pixels can be connected to one or more additional shift register elements in the horizontal CCD shift registers.
