ABSTRACT:
A video camera image with a motion induced blurring component is corrected by measuring the motion of the video camera by orthogonally mounted rate gyros each producing a signal that varies with camera motion along a defined axis relative to the bore sight of the camera. The video camera signal with the motion induced blurring component is processed into a Fourier transform which is combined with a video deblurring signal. Motion output signals of the rate gyros are processed in a Fourier transform computed Wiener filter to produce the video deblurring signal which is combined with the Fourier transform of the video camera signal. This combination signal is then processed in an inverse Fourier transform and converted into an analog signal for input to a video display monitor. This input signal to the video display monitor is motion corrected and produces a video display corrected for motion of the video camera.
