<P>PROBLEM TO BE SOLVED: To suppress ringing that occurs at a contour part while maintaining the effect of contour enhancement. <P>SOLUTION: This image data processor for performing contour enhancement processing of image data has: a contour enhancement part 20 for performing contour enhancement processing of luminance originally belonging to a pixel to be processed in the image data and outputting the contour enhanced luminance; a luminance limitation value setting part 30 for setting a luminance limitation value for limiting the contour enhanced luminance in accordance with the brightness of the color of the pixel to be processed; and a contour enhancement control part 40 for comparing the contour enhanced luminance with the luminance limitation value in magnitude and outputting proper luminance after contour enhancement in the pixel on the basis of the comparison result. <P>COPYRIGHT: (C)2009,JPO&INPIT |
