A solid state imaging device 1 includes a photodetecting section including M×N pixel portions P1,1 to PM,N two-dimensionally arrayed in M rows and N columns, a signal readout section including integrating circuits S1 to SN and holding circuits H1 to HN, and an initialization section including initialization switches SWI,1 to SWI,N. In response to a discharging control signal Reset, discharge switches SW2 in the integrating circuits Sn are temporarily closed and then opened, and thereafter, in response to an m-th row selecting control signal Vsel(m), the readout switches SW1 of the pixel portions Pm,n of the m-th row are closed for a first period. In this first period, in response to a hold control signal Hold, the input switches SW31 of the holding circuits Hn are switched from a closed state to an open state, and thereafter, in response to an initializing control signal Init, the initialization switches SWI,n are closed for a second period.
