Title: Correction circuit of dropout
Inventor: NISHIHARA MICHIHARU
IPC: H04N9/88
Filed: 1983-12-15
Abstract: PURPOSE:To prevent dropout from affecting its picture quality by a means for switching the 1st synchronizing signal of a luminance signal to the 2nd one and a means for synthesizing a color difference signal and a luminance signal through said means and for forming a reproduction video signal. CONSTITUTION:In response to a dropout detection signal, a switching circuit 12 selects and switches the 1st reproduction video signal to the 2nd one which delays the 1st one by one horizontal scanning period, and vice versa. A synchronizing signal forming means 14b of a synchronizing signal processing means 14 forms the 2nd synchronizing sgnals H2 and V2 in synchronization with the 1st synchronizing signals H1 and V1. A synchronizing signal switching means 14c replaces said signals H1 and V1 with H2 and V2. A synthesizing means 16 synthesizes a color difference signal (c) from a color difference signal processing means 15 and said luminance signal Y, which is outputted. Thus dropout generated in an input signal is corrected.
