Title:
ベクトル波形回転装置
Document Type and Number:
Japanese Patent JP4571381
Kind Code:
B2
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 alpha, 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 alpha-y.sin alpha, x.sin alpha+y.cos alpha) from the vector (x,y)=(first color difference signal, second color difference signal).
