Abstract
A video signal reproducing system including a still picture reproduction function is provided with correction circuitry for preventing the line jitter problem which often occurs in conventional units. A memory circuit is provided which has a capacity of at least one field, and receives a video input via a variable delay circuit. The output is derived, in alternate fields, from the memory circuit or a correction circuit. In one embodiment, the correction circuit may deliver a line interpolated signal derived by averaging the memory output signal and a 1-H delayed signal from the memory circuit.
