Abstract

PURPOSE:To effectively improve the uneasy feeling of a picture by placing an importance on a red color the most outstanding in the deterioration in a reproductivity in the high frequency band of a luminance signal generated as a result of a current gamma correcting system and correcting the reproductivity. CONSTITUTION:When an input is three primary color signals R, G, B, the movable piece S of switches Sa-Sg is placed at a position shown in the drawing. Since the switches Sa, Sb, Se, Sf are closed and Sc, Sd, Sg are opened, a matrix 11 and a chrominance signal modulator 16 generate an output, however, a color difference signal demodulator 12 does not generate the output. When the input is the TV signal of an NTSC system, the switch movable piece S is moved to a direction shown by an arrow and the opening and the closing states of the switches Sa-Sg are inverted. Consequently, the output of the matrix 11, the modulator 16 is not generated, but the output of the demodulator 12 is generated. When the luminance signal Y'' obtained in an adder 8 is used to broadcast or record a picture, the signal Y'' of a line 15 and the modulated chrominance signal C of a line 18 are guided to a Y/C synthesizer 19 to synthesize the NTSC system TV signal.
