Abstract
A method of transferring charges for a CCD image-sensing device. First, the K register elements (every k register elements) are defined as a charge-combining portion, thereby providing m charge-combining portions. The y image-sensing elements sense incident light energy to generate y charge packets proportional to the light intensity. Then, the y charge packets are transferred in a parallel manner to the CCD shift register. The charge packets coupled to each of the m charge-combining portions are accumulated into one specific register element when the k register elements have coupled the charge packets from the image-sensing elements, thereby generating m adding charge packets in the m charge-combining portions. Finally, each of the adding charge packets is serially delivered to the output of the CCD shift register, converting the adding charge packets into proportional voltage levels.
