主权项

1. A solid-state imaging device, comprising:
a pixel array section constituted by unit pixels arranged in a matrix, at least one of said unit pixels including a photoelectric conversion unit configured to convert an optical signal into signal charges, a transfer element configured to include a gate electrode and configured to transfer the signal charges obtained through photoelectric conversion of accumulated charges during an exposure period in said photoelectric conversion unit to a floating diffusion element and a reset element configured to reset the floating diffusion element; a vertical scanning circuit including a first driving section and a second driving section; a horizontal scanning circuit that outputs signals held in a set of at least one column circuit, wherein each column circuit receives the signals output by a row of pixels in the unit pixels selected by the vertical scanning circuit; the first driving section configured to, after resetting the signal charges and after the exposure period, drive said transfer element using at least one of a set of intermediate voltages that are each effective to provide only a partial transfer of the accumulated charges in the photoelectric conversion unit based on a charge capacity of the floating diffusion element when the reset element is turned off, the intermediate voltages being different voltage values that are applied to said transfer element; and the second driving section configured to drive said transfer element using another voltage that is different from said intermediate voltages, after the exposure period.
