Image processing device and method for adaptive edge enhancement

摘要

In an image processing device, in order to display an image on a display device the image being represented by image data (51) input from an image input device subjects the pixel data constituting the image data (51) to a luminance conversion process on the basis of the estimated, the pixel data of one or more character regions may be subjected to a sharpening process. The level of the sharpening performed for one or a plurality of extracted character regions in the image represented by the image data (51) is higher than that for the pixel data of the pixel in remaining regions other than the character regions in the image. The image data (52) comprising the pixel data subjected to this process is supplied to the display device. Therefore, the visibility of the image displayed on the display device can be improved.
