Abstract

PURPOSE: To obtain a high-contrast color picture with a high S/N by recording previously the character picture frame on the recording medium in the white/black mode and then adding the back color electrically to the video signals which are reproduced at the reproducing time.
CONSTITUTION: Synchronous signal generator 11 generates brust flag signal (a), blanking signal (b) and synchronous signal (c) each which are synchronized with the video signal of the output of color signal composite video amplifier 7. Subcarrier generator 12 generates continuous wave (d) of 3.58MHz, and phase shifter 13 generates continuous wave (e) obtained by giving the phase shift to wave (d). Waveform shaping unit 14 samples the signals or the like showing the pattern as well as the character signals from the output video signals of amplifier 7 to generate waveform-shaped signal (f). When color burst signal decidion unit 10 decides that no color burst exists to the output of amplifier 7, switches SW01∼04 are changed over to the opposite position to the diagram. And adding the color burst signal and the color signal to the reproduction video signal from signals (a)∼(c), (f) plus waves (d) and (e), color signal compounder unit 15 delivers NTSC color signal (g).
