  • Method and apparatus for enhancing detail in an image
    Patent number: 7742651
    Abstract: The detail in an image can be enhanced by selective filtering to separate at least one part of the frequency spectrum of the image from a remaining part of the image. The amplitude of the separated part of the frequency spectrum of image is changed and the amplitude-changed portion is combined with the remaining part of the image. The filtering and/or the change in amplitude is controlled at least in part in response to the content of the image to enhance the detail level of the image where appropriate, while preventing enhancement in areas of the picture where it is likely that artifacts would be generated.
