ABSTRACT:
A vector waveform rotation device (60) for rotating a vector waveform displayed on a vector comprises rotation amount setting means (5′) for holding a rotation amount α, and means (6′) for inputting a first color difference signal (B-Y signal) and a second color difference signal (R-Y signal) demodulated from a chrominance signal of a composite video signal as x and y, and rotating a vector (x, y) by generating a vector (x′,y′)=(x·cos α−y·sin α, x·sin α+y·cos α) from the vector (x,y)=(first color difference signal, second color difference signal).
