摘要: 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.

摘要: A system for monitoring the operation of a multichannel receiver includes a channel monitor coupled to the sync separator of the receiver for collecting and transmitting channel information to a central collector station. The collector station selectively responds to one of a plurality of channel monitors to record, in sequential order, channel information. Each of the channel monitors is similar and includes a synchronizing pulse generator triggered by the vertical synchronizing pulse from a receiver to generate a match recognize pulse when a frequency coupled to the receiver from the monitor and the channel frequency have a preestablished relationship. To generate the match recognize pulse a counter provides signals to a tuning matrix that controls a frequency synthesizer or plurality of oscillators for generating the frequency coupled to the receiver for the match evaluation. Also, the counter activates a data encoder that provides channel information to the collector station. The collector station responds to the channel information and records incoming data for future evaluation of the operation of the multichannel receiver.
