Abstract
PURPOSE: To obtain a perfectly-still picture with the phase made optimum easily in case of a still picture in any field, by selectively determining the phase of an artificial synchronizing signal by detecting the position of a noise band at the time of still picture reproduction.
CONSTITUTION: Noise-band detection circuit 17, consisting of a limiter circuit and AM detection circuit, AM-detects envelope signal (i) through the limiter circuit to detect noise band (e). Then, when output (e) is out of phase with the operation state of 1/2-counter 15, resetting is done by output (e). Next, signal Δt1 lagging by a large phase angle is assigned at artificial synchronizing signal VD to one field of vertical synchronizing signal VS, and signal Δt2 lagging by a small phase angle is to the other field; and the phase of VD is decided selectively by discriminating the phase of the noise band and mixing VS and VD together results in the optimum phase even when a still picture in any field comes, so that a completely-still picture can be obtained.
