Device and method for image processing
Abstract
A device and a method for image processing make it possible to significantly improve the contrast and the sharpness of the whole image, in comparison with the ordinary. By amplifying the portions other than the edges, while conserving the edges with the pixel values which change abruptly out of input image data, it is possible to enhance and display the portions other than the edges, and so it is possible to significantly improve the contrast and the sharpness of the whole image, in comparison with the ordinary.
