A solid-state image pickup device has one or more pixels and a voltage generation part. The or each pixel has a photodetection diode, a signal storage region, an insulated-gate field effect transistor, and a substrate. The voltage generation part applies a specified gate voltage and drain voltage to a gate and a drain, respectively, of the insulated-gate field effect transistor to balance a photocurrent generated at the photodetection diode and a current discharged to the substrate with each other at least during a signal read of the pixel so that the pixel is kept in a steady-state operating status that the photocurrent is flowing to the substrate via the signal storage region steadily.
