摘要： A driving method for a solid state image pickup device, having four or more transfer stages as one transfer unit, includes reading signal charge from the charge accumulation regions to the vertical charge transfer channels. The reading step includes (b-1) applying the barrier forming voltage to a first transfer electrode to form a barrier of at least one stage per the transfer unit; (b-2) applying the read pulse to a second transfer electrode to read signal charge from a corresponding charge accumulation region to a corresponding vertical charge transfer channel; and (b-3) applying a cancellation pulse to a third transfer electrode spaced by at least one transfer stage from the first transfer electrode, the cancellation pulse cancelling out a potential change in the charge accumulation region to be caused by the read pulse.

摘要： A method for driving a solid-state imaging element, which includes photoelectric conversion parts; vertical charge-transfer paths transferring signal charges from the photoelectric conversion parts in the vertical direction, each of the vertical charge-transfer paths including pairs of a first and second electrodes; and a horizontal charge-transfer path transferring the signal charge in a horizontal direction, is provided and includes applying driving pulses to the first and second electrodes to transfer the signal charge in the vertical direction. The transferring of the signal charge in the vertical charge-transfer paths is performed in such a way that when the signal charge is transferred from an electrode whose length is longer, a charge transfer time is lengthened, and that when the signal charge is transferred from an electrode whose length is shorter, a charge transfer time is shortened.
