ABSTRACT:
Method and apparatus for priority masking of video enhancement areas of a video picture. A first enhancement conversion formula is generated for enhancing a first segment of the video picture according to the first generated enhancement conversion formula. Similarly, a second enhancement formula for enhancing a second segment of the video picture according to the second enhancement conversion formula is generated. Priority of one conversion formula over the other in the area of overlap of the two segments is established by combining the first and second enhancement conversion formulas in a manner to produce the composite enhancement conversion formula in which one of the first and second enhancement conversion formulas has a degree of priority over the other enhancement conversion formula in the area of the video picture in which the overlapping occurs. The video picture is thus modified according to the composite enhancement conversion formula. When more than two segments having their individual enhancement conversion formulas, the composite enhancement conversion formula is established such that, in the area of common overlap of the three segments, one of the first, second, and third enhancement conversion formulas has a first degree of priority over the other two, and one of the other two enhancement conversion formulas has a second degree of priority over the other one thereof. In a preferred embodiment, the enhancement modification and conversion is the colorization of a black and white or an undesirably colored video picture.
