ABSTRACT:
A method of coloring a black and white video signal is provided. At least one area of a frame is defined with reference to luminance values in that frame, and luminance levels are assigned to that area. A color is then assigned to that area, and the area is colored with it. In a subsequent frame, luminance levels are used to determine which part of the preceeding frame has been carried over into the subsequent frame and which portions of the subsequent frame adjacent that part have the same luminance values. That part and those portions are then colored with the respective assigned color.
