This invention is directed to an electronic gimbal system (10) which stabilizes a digital video image of a particular scene taken by a sensor which is under disturbance forces. The video image is stored as a two-dimensional array of pixel locations (12) and is applied to an address look-up calculator (14) along with a signal from an inertial sensor (16). The inertial sensor (16) determines the offset of the array of pixel locations from an inertial reference frame and adjusts the input array accordingly. In one particular implementation the, address look-up calculator (14) applies a bilinear interpolation to the pixel location in order to provide a weighted sum of pixel intensities for each …

Why it's free to use
- Filed April 1, 1993 and granted May 11, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
