INTERPLATION SIGNAL GENERATING CIRCUIT

摘要

A system for generating interpolation signals for a progressive scanning conversion television system. The sysetem includes a Y/C separator for separating the luminance (Y) and chrominance (C) signals from a composite video signal, an interpolation Y signal generating circuit for receiving the separated Y signal and generating an interpolated Y signal, the interpolation Y signal generating circuit including at least one low pass filter to remove the high frequency signal components from the separated Y signal and a circuit to alternately provide the separated Y signal and the interpolated Y signal along with the C signal to generate a progressive scanning television signal.
