| Abstract: |
A method and apparatus for adaptively sharpening an image includes dividing the image area into smaller sub-areas each containing a sub-image, and adaptively sharpening each sub-area image individually. That is, the sharpening factor SF, and the blur area are automatically and adaptively set differently for each individual sub-area image of the original photograph. The sharpening effect is thus improved over the entire image area since each sub-area image of the original image is sharpened in accordance with the amount of sharpening needed. Areas with more detail needing more sharpening, would receive more sharpening, while other areas such as gray sky, receive almost no sharpening.
