ABSTRACT:
A video signal processing device comprises: a unit for extracting a first color burst signal from a first video signal; a unit for generating a first subcarrier in synchronism with the first color burst signal extracted from the first video signal; a unit for extracting a second chrominance signal and a second color burst signal from a second video signal; a unit for demodulating the second chrominance signal and the second color burst signal on the basis of the first subcarrier to obtain a demodulated second color signal and a demodulated second color burst signal; and an operating unit for performing operation process of the demodulated second color signal on the basis of the demodulated second color burst signal in a manner such that the demodulated second color signal is converted into a corrected color signal which is substantially the same as an imaginal second color signal which is obtained on the assumption that the second chrominance signal is demodulated on the basis of a second subcarrier synchronized with the second color burst signal extracted from the second video signal.
