Abstract
An Image correction device for detecting an image area having movement according to an image signal, and providing the image signal with image correction and switching correction methods according to a control signal. The image correction device further detects the boundary area of the image area having movement; detects an image area with great gradational change by comparing gradation of image signals corresponding to adjoining pixels; and provides the boundary area of the image area having movement with a diffusion process in an area excluding the image area with great gradational change. The correcting methods performed by the image correcting device can be switched according to the movement signal, thereby improving image correction.
