Open the CIPO recordAbstract From the Canadian patent
An imaging system produces undistorted image data from buffered wide-angle image data without the need for a separate output buffer. Wide-angle image data is transformed on a pixel-by-pixel basis, as the data for a pixel is required for encoding to produce output signals in real-time. Predetermined values for functions used in the transformation process are obtained from one or more look-up tables to facilitate transformation.

Why it's free to use
- Filed April 21, 2004 and granted July 7, 2015. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 21, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 21, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
