ABSTRACT:
A solid-state imaging device includes a light receiving section (LRS) comprising pixels. The LRS is divided into division regions; a charge transferring section (CTS) transferring charges accumulated in the LRS; an accumulation control electrode provided between the LRS and the CTS transfers charge accumulated in the LRS to the CTS responsive to an accumulation control signal; a monitoring sensor group comprising monitoring sensors respectively provided for the division regions, outputting sensor outputs of the monitoring sensors corresponding to charges amounts of the division regions; a charge detecting circuit outputting a charge detection signal indicating that a predetermined charge quantity is accumulated in at least one of the division regions, based on the sensor outputs from the monitoring sensor group; and a signal control circuit outputting the accumulation control signal in response to the charge detection signal. The charge detecting circuit comprises division region charge detecting sections for the monitoring sensors.
