A solid-state imaging apparatus includes a photoelectric conversion unit for generating and accumulating an electric charge according to an incident light, a floating diffusion for accumulating electric charges, a transfer transistor for transferring electric charges accumulated in the photoelectric conversion unit to the floating diffusion unit, and a reset transistor for resetting a voltage according to electric charges accumulated in the floating diffusion unit. In addition, a drive circuit intermittently applies to a gate of the transfer transistor a pulse having a first potential which is intermediate between a transfer potential for transferring electric charges and a non-transfer potential for disabling transfer of electric charges and applies to a gate of the reset transistor a second potential lower than the potential of the pulse for resetting voltage of the floating diffusion unit and higher than the first potential, during accumulation of electric charges in the photoelectric conversion unit.
