A solid state imaging apparatus includes a solid state imaging device and a control circuit for performing control such that a first clock signal applied to transfer signal charges for a time period from after a preceding signal charge has been read out from a light sensing unit to when the preceding signal charge is transferred to a horizontal transfer unit and a second clock signal applied for a time period from after the preceding signal charge has been transferred to the horizontal transfer unit to when a succeeding signal charge is read out from the light sensing unit have almost the same amplitude and a high level potential of the first clock signal is set higher than that of the second clock signal.
