ABSTRACT:
An object of the invention is to provide a solid state imager device in which an electronic shutter function is provided and charges never overflow a light receiving portion even when the light with a high intensity enters thereinto and to provide the driving method thereof. In the solid state imager device and the driving method, an electronic shutter operation is conducted by sweeping out the charges in the light receiving portion by applying a predetermined voltage to a substrate, and the voltage application period is within a horizontal blanking period when an effective exposure period of the electronic shutter exceeds a vertical blanking period and the voltage application period covers an effective horizontal scanning period when the effective exposure period is within the vertical blanking period.
