ABSTRACT:
A solid-state camera device of the present invention includes a semiconductor substrate, a plurality of charge storage regions formed on the semiconductor substrate, a charge transfer region formed on the semiconductor substrate, for transferring charges read from the plurality of charge storage regions, a bias charge injection diode formed on the semiconductor substrate, for injecting a bias charge into the charge storage region, and sweeping out section for sweeping at least part of the charge remaining in the charge transfer region before resetting part of the bias charge injected into the charge storage region to emit part of the bias charge into the charge transfer region. That is, the present invention has a feature that the residual charge lying in the charge transfer region below the transfer gate specified for reading is swept before resetting the bias charge after injecting the bias charge into the charge storage region.
