摘要： With the use of the MOS-type solid-state imaging device, it is possible, by extending the period during which the VDD voltage rises from Low level to High level, that the gate voltage of the resetting unit does not fluctuate to have a positive electric potential due to the coupling capacitance between the VDD power and the gate of the resetting unit, unlike the conventional case. Consequently, the electrons necessary for rendering the accumulation unit non-selectable do not flow from the accumulation unit to the VDD power. This prevents the level of the electric potential in the accumulation unit of non-selectable row from becoming positive. Also, the detecting unit is not switched on, which prevents the error of selecting a non-selectable row.

摘要： In each pixel of a MOS-type solid-state imaging device, a plurality of first signals and one or more second signals are accumulated in a plurality of storage areas in a storage unit during driving. Here, each of the plurality of first signals corresponds to a light receiving signal (light receiving signal on which noise is superimposed) which is transmitted from a light receiving unit each time a switching unit is in a closed state, and each of the one or more second signals is a signal (noise such as dark-current noise, fixed pattern noise, and the like) as a voltage of a signal readout path when the switching unit is in an open state. Also, in the solid-state imaging device of the present invention, each of the one or more second signals in the storage unit of each image pixel is in a state of being physically or temporally separated from each of the plurality of first signals.
