Abstract
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 offset pixel location.
