Abstract
An analog line store comprises a bank of storage capacitors n in number, an n:1 read multiplexer for sequentially sampling from the n storage capacitors as part of a read-then-write operation, a 1:n write multiplexer for sequentially sampling to the n storage capacitors as a further part of the read-then-write operation, and a scanning register for generating control signals for the write multiplexer and the read multiplexer. The storage capacitors have similar capacitances that are substantially invariant with change in stored charge. Such an analog line store is integrated together with a solid-state imager array to provide for the cancellation of fixed pattern noise from the imager video output signal.
