Solid-state image pickup device operable at a frame rate with a controllable accumulating time interval

摘要

In a solid-state image pickup device comprises a solid-state image pickup section (10) including a substrate and a plurality of photoelectric converting sections formed on the substrate, the photoelectric converting sections accumulates, in response to incident light, electric charges during a controllable accumulating time interval in each frame period as signal charges in synchronism with a frame rate. Connected to the substrate, electronic shutter means discards disused charges during a discarding time interval in the frame period from the photoelectric converting sections to the substrate. The discarding time interval is equal to a difference between the frame period and the controllable accumulating time interval. Connected to the solid-state image pickup section, a timing pulse generating section (20) controls the controllable accumulating time interval. <IMAGE>
