ABSTRACT:
A method and apparatus for processing a raw video camera signal to identify undesired multidimensional video image motion caused by rotational or translational camera motion in two or three dimensions, and to generate a corrected video camera signal in which such undesired video image motion is reduced. In a preferred embodiment, the apparatus includes a video camera having an oversized image pickup device, four accelerometers mounted in the video camera, and means for processing the accelerometer output signals and the raw video camera output signal to generate a corrected video camera signal. The processing means preferably employs selective clocking to generate a corrected video signal representing a stabilized version of the view of interest. Such a corrected video signal will exclude extraneous visual information (i.e., visual information other than the view of interest), and will be "stabilized" in the sense that it exhibits less image motion than does the draw video camera signal. The preferred embodiment of the invention is capable of efficiently correcting for undesired camera rotation about three orthogonal rotational axes, as well as for undesired camera translations in a plane orthogonal to the axis of symmetry of the camera lens.
