ABSTRACT:
An image sensing apparatus for picking up images having a solid-state image sensor provided with an antiblooming gate. The antiblooming gate removes unnecessary electric charge at a given frequency rate during a period of time at which an exposure shutter reaches a desired aperture diameter. The antiblooming gate removes unnecessary charge at a lower frequency rate before and/or after the exposure shutter reaches the desired aperture diameter. Thus it is possible to provide a highly efficient antiblooming system that minimizes the duration in which the antiblooming gate operates at the higher frequency rate, thereby minimizing undesirable conditions associated with operating the gate at the higher frequency rate.
