Abstract
A plurality of video signals of which colorimetries are different with each other are inputted. YCrCb-to-RGB conversion circuits converts at least two video signals having different colorimetries to an RGB color signal having a single colorimetry with matrixes corresponding to the colorimetries switched. An RGB-to-YCrCb conversion circuit may be further provided to convert the RGB color signal to a YCrCb signal again to supply it to a display with colorimetry matched to the display.
