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.

摘要: Video processing delays are compensated for to maintain synchronism of audio with the video. The delay is determined by correlating a signal derived from a displayed light image with a pre-processed video test signal from which the image was produced.
