Abstract
A method and apparatus for changing a video image having a number of luminance areas to a drawing-style image. An edge boundary between two luminance areas of the video image may be detected and a key signal may be generated therefrom. The key signal may be nonlinear transformed to generate a transformed key signal. Two color signals may be mixed in accordance with the transformed key signal so that the boundary of the video image may be displayable as a line in the drawing-style image.
