A solid state imaging device 1 includes a photodetecting section including M×N pixel portions P 1,1 to P M,N two-dimensionally arrayed in M rows and N columns, a signal readout section including integrating circuits S 1 to S N and holding circuits H 1 to H N , and an initialization section including initialization switches SW I,L to SW I,N . In response to a discharging control signal Reset, discharge switches SW 2 in the integrating circuits S n are temporarily closed and then opened, and thereafter, in response to an m-th row selecting control signal Vsel(m), the readout switches SW 1 of the pixel portions P m,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 SW 31 of the holding circuits H n are switched from a closed state to an open state, and thereafter, in response to an initializing control signal Init, the initialization switches SW I,n are closed for a second period. |
