  • Image processing method
    Patent number: 7076112
    Abstract: A method for processing an image is provided. A first image and a second image are provided, and donor pixels in the first image are located which correspond to active pixels on the second image. One of the channels of the first image is selected and a donor pixel is chosen. The pixels of the first image are searched in the region of the donor pixel in order to determine suitable receiver pixels. A transfer of luminance is performed from the donor pixel to these receiver pixels through the receiver pixel array. A second donor pixel is then selected, another search is carried out and a transfer of luminance is again performed. This process is then repeated for each donor pixel.
