Abstract: A method for combining a first digital image and a second background digital image, both images including pixels having color values, wherein the first digital image includes both a foreground region having foreground color values and a key color region characterized by a key color, as well as a mixed region where the pixel color values are a mixture of the foreground color value and the key color, includes determining a first control signal that indicates the relative proportions of the foreground color value and the key color for pixels in the first digital image; and segmenting the first digital image into a key color region and a non-key color region in which the non-key color region includes pixels in the first digital image that are not in the key color region. The method also includes determining a second control signal that indicates a spatial distance between the pixels in the first digital image and a boundary between the key color region and the non-key color region; and combining the first digital image and the second background digital image in response to the first and second control signals, the key color, and an illuminant color value.

Abstract: Multi-channel color image signals from a digital camera having multi-channel image sensors are corrected to account for variations in scene illuminant. This is accomplished by determining the scene illuminant and determining an optimum color-correction transformation in response to the scene illuminant which transform minimizes color errors between an original scene and a reproduced image by adjusting three or more parameters.

Abstract: An error diffusion method suitable for producing an output image from an input image having a set of digitized continuous-tone pixels is disclosed. The method includes the steps of computing an image activity signal; computing a set of activity weights from the image activity signal; computing a filtered input value for a digitized continuous-tone input pixel responsive to the activity weights and computing a filtered output value responsive to the activity weights for each of the possible output levels. The method further includes selecting the output level in response to the filtered input value and the filtered output value for each of the possible output levels according to an error criterion; determining an error signal between the filtered input value and the filtered output value for the selected output level; and weighting the error signal and adjusting the filtered input values for nearby pixels which have not yet been processed.
