In a driving method of device having plural pixels, each pixel comprises photoelectric converter, floating diffusion, transfer transistor to transfer charge of the photoelectric converter to the floating diffusion, amplifying transistor to amplify signal based on the transferred charge, and reset transistor to reset voltage of the floating diffusion, the method comprises first step of, after putting the transfer transistor into conduction state, resetting the charge of the photoelectric converter by putting the transfer transistor into non-conduction state in non-conduction state of the reset transistor, and second step of, after the first step and after putting the transfer transistor into the conduction state, transferring the charge of the photoelectric converter to the floating diffusion by putting the transfer transistor into the non-conduction state in the non-conduction state of the reset transistor, and the signal based on the charge transferred in the second step is amplified by the amplifying transistor.
