An encoding method and apparatus for conditioning video signal to reduce contouring in images reproduced from compressed video signal involves preconditioning the video signal, prior to completion of compression, to effectively amplify noise in portions of the video signal representing relatively smooth image areas. In an exemplary embodiment, a memory is programmed at respective address locations to remap amplitude values of a digitized signal applied as addresses to the memory. The programming is arranged to enlarge a range of lower amplitude values, and to effectively pass higher amplitude values unaltered.
