ABSTRACT:
For enhancing an image, particularly a pixel image, the image is separated into brightness information and detailed information, the detailed information is enhanced, and then the enhanced detailed information is combined with the brightness information to produce an enhanced image. The entire process may be performed on a real time basis with the scanning, without artifact and any space transformation such as Fourier transform.
