COLOR DIFFERENCE ENHANCEMENT CIRCUIT, COLOR DIFFERENCE ENHANCEMENT METHOD, AND COLOR DIFFERENCE ENHANCEMENT PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a color difference enhancement circuit, a color difference enhancement method, and a color difference enhancement program capable of accurately correcting a color difference signal having a pulse shape by pixel.;SOLUTION: A color difference enhancement circuit 1 is provided to correct the color difference signal of each of plural pixels and comprises a color difference ε filter part 30. On the basis of a luminance color difference that is a difference between the luminance value of the luminance signal of the pixel to be corrected and the luminance value of the luminance signal of a reference pixel to be used for correction of the pixel to be corrected, the color difference ε filter part 30 subjects a color difference signal of the pixel to be corrected to filter operation for enhancing a color difference edge.;COPYRIGHT: (C)2012,JPO&INPIT
