ABSTRACT:
In an electronic still camera the time lag between shutter release and exposure of a solid state image pickup device is reduced by reducing the time required to discharge accumulated unnecessary charges (e.g., to remove noise caused by dark current). More particularly, the repetition rate of signals employed to discharge odd and even pixel fields of the pickup element is increased during an interval starting with a shutter release signal.
