ABSTRACT:
A method for gradually adjusting intensity of a color component of pixels of successive images in a video data includes the steps of: a) providing an offset value; b) adding the offset value to the color component of each of the pixels of the successive images of the video data to generate an adjusted color component; c) setting a frequency factor indicative of times of adjustment of the offset value, the frequency factor corresponding to a number of the successive images per adjustment of the offset value; and d) adjusting the offset value in a predetermined manner in accordance with the frequency factor. An apparatus for gradually adjusting intensity of the color component is also disclosed.
