In an imaging apparatus having plural pixel units each including a photoelectric conversion portion, each pixel unit has a writing transistor WT and a reading transistor RT each including a floating gate FG disposed on a semiconductor substrate so as to accumulate electric charges generated in the photoelectric conversion portion, and the imaging apparatus includes a control unit independently performing a first charge discharging drive operation of discharging the electric charges generated in the photoelectric conversion portion of each pixel unit in a group to a writing drain WD or a reading drain RD in the pixel unit by groups including plural pixel units and controlling an exposure period start time of each group.
