Zusammenfassung:The invention provides a high dynamic response range CCD image sensor with a plurality of horizontal shift registers; the back of each horizontal shift register is connected with two multiplication registers with the multiplication coefficient of one being greater than that of the other. The back of each multiplication register is connected with an amplifier. In addition, electric charge packet signal splitting units are arranged among the horizontal shift registers and the multiplication registers. The electric charge packet signal splitting units split the electric charge packet signals transmitted from the horizontal shift registers into two electric charge packets of varied sizes wherein the bigger electric charge packet signals are transmitted into the multiplication registers with the maller multiplication coefficient while the smaller electric charge packet signals are transmitted into the multiplication registers with the bigger multiplication coefficient. According to the invention, electric charge p
