Abstract
A video signal processing circuit that uses a prescribed clock signal to process a digitized composite video signal. A clock generating means () generates the prescribed clock signal; a burst phase detecting means () detects color subcarrier phase information (p) in each line of the composite video signal; a phase difference calculation means () finds the phase difference between phase information (p) from the burst phase detecting means and a prescribed reference phase; a sampling phase conversion means () corrects the sampling phase of the composite video signal according to phase corrections (Δb, Δt) obtained from the phase difference calculation means (); a Y/C separation means () separates the luminance and chrominance signals from the composite video signal output from the sampling phase conversion means (). Excellent two- or three-dimensional Y/C separation can be obtained regardless of the television broadcast system, even from a non-standard signal.
