ABSTRACT:
A CCD image sensor having a linear array of individual imaging photodetecting cells aligned along a scanning line for sensing light information and converting the light information to charge carriers. A CCD shift register, adjacent to the linear array of photodetecting cells, is used for receiving and temporarily storing the charge carriers generated by the photodetecting cells of the linear array. The CCD shift register has a plurality of CCD cells, each of the photodetecting cells being associated with at least two CCD cells such that there is an imaging CCD cell for receiving the charge carriers from the associated photodetecting cell, and at least one buffer cell for receiving a pre-loaded signal to reduce charge transfer inefficiency of the charge carriers. A pre-loaded signal is injected into the buffer cells of the CCD shift register and all the cells are clocked out such that the pre-loaded buffer cells are clocked through the image cells to improve charge transfer inefficiency characteristics.
