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. <IMAGE> |
