PURPOSE: An amplification solid state image sensing device including pixels having an amplification function is provided to reduce reset noise and image sticking with a simple configuration and to maintain linearity of an output signal for an input optical signal. CONSTITUTION: An amplification solid state image sensing device includes a plurality of pixels(10) and a controller. Each of the pixels includes a photo-electric conversion region(4), a signal amplification field effect transistor(1) for amplifying a signal corresponding to the potential of the photo-electric conversion region, a reset field effect transistor(2) for discharging charges of the photo-electric conversion region to its drain, and a pixel selecting field effect transistor(3). The controller sequentially repeats a signal level reading period, the first reset period, a reset level reading period, the second reset period and the third reset period. During the signal level reading period, the potential level of the photo-electric conversion region is read through the signal amplification field effect transistor. During the first reset period, the reset field effect transistor carries out a soft reset operation by sub-threshold current. The potential level of the photo-electric conversion region, obtained by the soft reset operation, is read through the signal amplification field effect transistor during the reset level reading period. The reset field effect transistor carries out a hard reset operation to fix the potential of the photo-electric conversion region to a drain potential during the second reset period. The reset field effect transistor performs the soft reset operation by the sub-threshold current during the third reset period.
