Abstract
PURPOSE:To vary a signal charge storage time of a photodiode by sweeping out an undesired electric charge of the n-th row of the photodiode by an overflow drain part of an optional photodiode on the next and succeeding rows. CONSTITUTION:The undesired charge of the n-th row of the photodiode 1 is transferred to the (n+1)th row of photodiode 1 via, e.g., the (n+1)th row of vertical transfer channel part 3 by using an output pulse of an undesired charge readout shift register 12 and an undesired charge readout register 13 and swept out to an overflow drain 14 through an overflow control gate section 15. When the storage time of the signal charge is varied, the undesired charge of the (n+m)th row is swept out during the horizontal blanking period reading out the signal charge of the n-th row.
