Abstract
An image enhancement method and an image enhancement apparatus is provided, wherein a multiple-gray-level converter of a grayscale converter converts an original two-grayscale image, an image enhancement device enhances the resultant image so that gray values for the outline of the image are smoothly changed, and a two-gray-level converter converts the enhanced image to a two-grayscale image by referring to a specific value that is set in advance. The image enhancement method and the image enhancement apparatus of the present invention resolve the conventional problem of jaggies that appear in the outline of an enhanced image and make the image appear unattractive, and they thus produce a high quality enhanced two-grayscale image that has a smoother outline.
