<P>PROBLEM TO BE SOLVED: To provide an image processor capable of displaying an image in which the occurrence of moire is reduced in magnifying or reducing the image, without degrading image quality, even if there is a region containing high frequency components such as a checkered pattern, and to provide an image processing method and an image display device. <P>SOLUTION: The image processor includes: a high-frequency component detecting unit 12 that performs convolution operation for each of regions of interest in a part of an image region of input image data Da, to output a high-frequency component detection result Sb for each of pixel of interest; a smoothing unit 11 that outputs smoothed image data Dd obtained by smoothing image data Da; and an image data processing unit 13, that outputs high-frequency component processing image data Db, obtained by combining the image data Da with the smoothed image data Dd for each of regions of interest, on the basis of the high-frequency component detection result Sb, wherein the image data processing unit 13 varies a combination rate Sc for the smoothed image data, on the basis of the value of the high-frequency component detection result Sb. <P>COPYRIGHT: (C)2009,JPO&INPIT |
