摘要:
A vector waveform correction device corrects a vector waveform displayed on a vector scope. A first color difference signal and a second color difference signal demodulated from a chrominance signal of a composite video signal are input as x and y, and a vector (x, y) is partially rotated in a unit of part of all the scanning lines.
