A weighted average section takes an average by weighting the upper layer and the lower layer by using the interpolated background to generate an interpolated image.

Why it's free to use
- Filed May 16, 1997 and granted October 22, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 16, 2017.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
