Abstract:
A color difference signal correction apparatus comprising:a first full-wave rectification means for receiving a (Râˆ’Y) color difference signal and full-wave rectifying the (Râˆ’Y) color difference signal; a second full-wave rectification means for receiving a (Bâˆ’Y) color difference signal and full-wave rectifying the (Bâˆ’Y) color difference signal; a first addition means for adding an output of the first full-wave rectification means and an output of the second full-wave rectification means; a second addition means for receiving a white character slice level signal, and adding the white character slice level signal and an output of the first addition means; a slice means for receiving a luminance signal and slicing the luminance signal with an output of the second addition means; and a third addition means for adding an output of the slice means and the (Bâˆ’Y) color difference signal.
