    摘要: The novel method of electronic color image processing comprises: inputting an image; obtaining a color (A) based on colors present in at least a first part of the image; and changing a saturation correlate (S2) defined with respect to the color (A) for at least a second part of the image. This allows for better quality saturation modification on a larger number of possible input images.

    摘要: The present invention is directed to a method of saturation correction. The method includes converting a luminance signal and at least one color difference signal into a color signal. Detecting if the color signal has a negative value. Inverting the color signal to produce a correction value. Further, adding the correction value to the luminance signal.
