Two-dimensional charge-coupled device for high-resolution image pickup and the like
First Claim
1. In combination, two dimentional charge-coupled device means including means for supplying a first electrical wave comprising video signal portions of substantially a predetermined period, said wave portions being spaced by substantially said predetermined period, delaying means for supplying at least one replica of said first electrical wave each delayed by a different integral multiple of said predetermined period, and means for algebraically summing said first electrical waves and said delayed replicas thereof, wherein said summing means includes switching means operable at a rate given by said predetermined period for converging said video signals supplied by said charge-coupled device means.

Abstract
A two-dimensional charge-coupled device for relatively high resolution image pick up includes an imaging area, a storage area, and plural output registers for developing plural video signals delayed by predetermined intervals, e.g., integral multiples of one horizontal line trace period. The several register output signals are combined to provide a composite video signal characterized by a greater resolution vis-a-vis the direct CCD output.
