To reduce the number of input/output terminals to reduce the diameter of a cord connected to a solid-state image pickup device of interline CCD(charge coupled device) used in a medical endoscope or the like.

Load transistors TRs 13 and 14 of an output amplifier 101 are formed with depletion MOS TRs, and gates of these MOS TRs are grounded. An output gate 7 is grounded. A first transfer electrode of a horizontal CCD 5 is grounded, and a second transfer electrode is connected to a single- phase signal input terminal 61, and a stepwise inclined electric potential area is formed under each transfer electrode. A first transfer electrode and a second transfer electrode of a vertical CCD 3 are connected to two-phase signal input terminals 41a and 41b respectively, and a stepwise inclined electric potential area is formed under each transfer electrode. A reset pulse generation circuit 21 is formed between the single-phase signal input terminal 61 and a reser gate 9.
