Abstract
Abstract An image sensing device comprises a light receiving unit having light receiving elements for producing electric charges corresponding to intensity of light received by the light receiving elements; an accumulator for accumulating the electric charges produced by the light receiving unit; a transferring unit for transferring the accumulated electric charges in response to a predetermined transfer clock; a discharge unit for discharging electric charges received; a first gate between the accumulator and the transferring unit for controlling the transference of the accumulated electric charges to the transferring unit; a second gate between the transferring unit and the discharge unit for controlling the transference of the electric charges in the transferring unit to the discharge unit; a gate control for controlling the first and second gates to interrupt the transference of electric charges through the first and second gates for performing the accumulation of the accumulator, to permit the transference of accumulated electric charges to the transferring unit after the accumulation of the accumulator is terminated, and to permit the transference of electric signals through the first and second gates to the discharge unit prior to commencement of the accumulation for discharging unnecessary charges in the accumulating unit and the transferring unit.
