In the imaging device, a light receiving > element and a vertical transfer passage are common. The accumulating > period calculating processor obtains an accumulating period, for > which a > signal charge is accumulated in the light receiving element, by a > calculation. The light receiving element is provided with first and > second electrodes to which voltages are applied. During the > accumulating > period, the voltage control processor fixes a voltage level of the > first > electrode and changes periodically a voltage level of the second > electrode in accordance with a length of the accumulating period, so > that a charge pumping operation is performed. > > ---------------------------------------------------------------------- > -- > Inventors: *Sato; Koichi* (Saitama, *JP*) > Assignee: *PENTAX Corporation* (Tokyo, *JP*) > Appl.
