Abstract: Target color table generated from source color tables. A first significance factor is assigned to a first node in a first source color table. The first node in the first source color table corresponds with a color input in a first color space and provides a first print substance formulation in a second color space. A second significance factor is assigned to a second node in a second source color table. The second node in the second source color table corresponds with the color input in the first color space and provides a second print substance formulation in the second color space. A third node in target color table is generated from the first and second nodes based on the first and second significance factors. The third node corresponds with the color input in the first color space and provides a third print substance formulation in the second color space.

Abstract: A method for processing a detected eye of an image to provide visual enhancement. The method includes determining whether an eye exists within an image. The eye includes an eye color. If the eye exists within the image, the method also includes determining the location of the eye within the image. Furthermore, the method includes processing the eye to provide visual enhancement to the eye without substantially changing the hue of the eye color of the eye.

Abstract: A method of one embodiment of the invention is disclosed that determines to output an output pixel for a color component of an image pixel. In response to determining to output the output pixel for the color component of the image pixel, the method outputs this output pixel, and at least substantially precludes output of output pixels for other color components of the image pixel.

Abstract: Disclosed are methods of halftoning images having multiple color planes using error diffusion techniques, and incorporating both error information from the previously-processed color planes of a pixel, and error information from a previously process pixel of yet-to-be processed color planes.

Abstract: One or more ink-usage parameters are adjusted based on ink remaining and historical ink usage, to reduce ink usage for an image to be printed on a sheet of media with ink. The image is printed on the sheet of media with the ink, in accordance with the ink-usage parameters. Adjustment of ink-usage parameters and printing an image on a sheet of media with the ink are repeated for each additional image to be printed on a sheet of media.

Abstract: A method for compensating for induced artifacts on an image to be printed includes processing the image to be printed. An image region of the image susceptible to at least one artifact is identified. An imaging process is modified to reduce an effect of the at least one artifact on the image region. The image is printed.

Abstract: A method for processing a detected eye of an image to provide visual enhancement. The method includes determining whether an eye exists within an image. The eye includes an eye color. If the eye exists within the image, the method also includes determining the location of the eye within the image. Furthermore, the method includes processing the eye to provide visual enhancement to the eye without substantially changing the hue of the eye color of the eye.

Abstract: A method for processing a human facial region of an image differently than the remaining portion of the image. The method includes determining whether a human facial region exists within an image. If the human facial region exists within the image, the method also includes determining the location of the human facial region within the image. Additionally, the method includes processing the human facial region differently in terms of spatial image enhancement than the remaining portion of the image.

Abstract: A method of one embodiment of the invention is disclosed that determines to output an output pixel for a color component of an image pixel. In response to determining to output the output pixel for the color component of the image pixel, the method outputs this output pixel, and at least substantially precludes output of output pixels for other color components of the image pixel.

Abstract: A method for improving the quality of arbitrary digital images with an input pixel window having an input pixel is provided to calculate variation in the pixel window, compare the variation in the pixel window to a predetermined threshold value, and process the input pixel based upon the comparison.
