を特徴とするカラーフレーム検出回路。 In a synchronization signal generator having synchronization separation, burst reproduction, and field detection functions, there is provided a means for converting a subcarrier signal obtained by burst reproduction into a pulse signal having a constant pulse width, and a phase between the pulse signal and the field detection output signal. A color frame detection circuit is characterized in that it stably detects a color frame signal by means of comparison.
