ABSTRACT:
A method and apparatus for cross color and/or cross luminance suppression. The apparatus checks for three conditions in determining the stillness of an image. Similarity between two frames, which are one frame apart, is examined. Similarity between two adjacent frames is also examined. Similarity among three successive frames is also examined. By integrating the results of such three conditions, the stillness of the image is determined. Only when the image is deemed still/stationary, is the cross color and/or cross luminance suppressing operation being performed.
