Abstract

PURPOSE:To curtail exhausting time and realize power saving by providing a discharge means which expels unwanted charges in the pixels to a semiconductor substrate of a first conductivity type under the condition that these charges are transferred to the vertical transfer section. CONSTITUTION:When unwanted charges are accummulated to the pixel 12, potentials at the positions A and D of n-type semiconductor substrate 10, position B of pixel 12 and position C of vertical transfer section 14 are shown in Fig. a. Here, a high potential pulse is applied to the vertical transfer electrode 15, the potential of vertical transfer section 14 is lowered than that of pixel 12 as shown in Fig. b and the unwanted charges are transferred to the vertical transfer section 14 through a transfer gate 13. Next (Fig. c), potential of vertical transfer section 14 is lowered than the potential of the p-type semiconductor layer 11, controlled to the pinch-off condition in the vertical transfer section 14 and unwanted charges are expelled to the n-type semiconductor substrate 10 (Fig. d).
