ABSTRACT:
OSD data YD includes a color designating signal As and a color changing signal Ex. When a color register number is designated by the color designating signal As, a color storage unit41outputs an appropriate color signal. A Y signal is branched from the outputted color signal and subjected to a modulating process by the color changing signal Ex. The Y changing signal obtained by the modulating process is merged with a Cb signal and a Cr signal so as to form new color signal. The OSD data YD with changed color is subjected to a synthesizing process with image data XD according to the predetermined mixture ratio.
