ABSTRACT:
A solid-state imaging apparatus including: an image section having a plurality of pixel units arranged into a matrix, each pixel unit having at least one subunit consisting of an electric charge generation means for generating signal electric charges corresponding to the amount of incident electromagnetic wave and a signal transfer means for transferring signal electric charges generated by the electric charge generation means, an electric charge accumulation means for accumulating the transferred signal electric charges, a first reset means for resetting the electric charge accumulation means, an amplification means for amplifying a signal corresponding to signal electric charges accumulated at the electric charge accumulation means, and a select means for selectively outputting the amplified signal to a vertical signal line; and a signal transfer assisting means for making a gradient of potential in the vicinity of the electric charge generation means toward the signal transfer means to be greater at the time of transfer of the signal electric charge than at the time of non-transfer.
