Image correction device ( 100 ), which has movement detecting means ( 120 ) for detecting an image area having movement according to an image signal and image correcting means ( 170 ) capable of providing the image signal with image correction and switching correction methods according to a control signal, further contains movement boundary detecting means ( 130 ) for detecting the boundary area of the image area having movement; gradational change detecting means ( 140 ) for detecting an image area with great gradational change by comparing gradation of image signals corresponding to adjoining pixels; and movement signal modulating means ( 160 ) for providing the boundary area of the image area having movement with a diffusion process in an area excluding the image area with great gradational change. With the structure above, switching the correcting methods of the image correcting means ( 170 ) according to the output of the movement signal modulating means ( 160 ) realizes an improved image correction. |
