摘要： This invention is related to a video signal color correction device. Color information signal inputs are received in rectangular form. A coordinates conversion means converts the inputs into polar coordinates using one of the inputs as a polar axis. The device has a correction data storing means in which are stored luminance signal correction data dependent on a luminance signal and the polar coordinates and color information signal correction data. The correction data storing means outputs the luminance signal correction data and the color information signal correction data in accordance with the luminance signal and the polar coordinates. A correction means corrects the luminance signal and the polar coordinates on the basis of the luminance signal correction data and the color information signal correction data output from the correction data storing means. The correction means may include addition means for adding the luminance signal correction data to the luminance signal and the color information signal correction data to the polar coordinates.
