PROBLEM TO BE SOLVED: To provide a drive method capable of realizing a solid-state imaging apparatus that has an improvement effect of its dynamic range ten thousands times of that of conventional solid-state imaging apparatuses, keeps linearity in its incident light versus signal quantity characteristic in 80% of the region of an object processed by the conventional solid-state imaging apparatuses, has linearity within 10% for the remaining 20%, and further has a broad dynamic range without signal saturation for an incident luminous quantity region with luminance of 4 digits or over. SOLUTION: The solid-state imaging apparatus disclosed herein includes an automatic switching function adopting the drive method that drives a drive voltage to a function control circuit section for controlling an applied voltage to a photoelectric conversion element section by means of the storage system in regions of a low luminance object and drives a drive voltage in regions of a high luminance object by means of the logarithmic transform system.
