摘要： The video contour correction system for a video display unit consists of an auxiliary deflection coil having coil axis parallel with the axis of the horizontal deflection coil of the cathode-ray tube, a differentiating circuit for detecting the primary differential waveform of a video signal and an am- olification circuit for amplifying the output of the differentiat- ng circuit. The output current of the amplification circuit is supplied to the auxiliary deflection coil so that the magnetic field produced by said auxilliary deflection coil is superposed on the horizontal deflection magnetic field produced by said horizontal deflection coil, thereby improving the bor- jer contrast of the picture.

摘要： A system for, and method of, enhancing a digitized image signal according to a helper signal architecture are described. The architecture includes an analysis filter (710), responsive to a digitized image signal, for filtering the digitized image signal, corresponding to a first frequency band, to produce a first frequency band signal. The first frequency band signal is then applied to a point operator (720), which modifies the first frequency band signal in accordance with a non-linear characteristic. The non-linear characteristic includes a first region having a negative slope for low amplitude input signals. The non linearity further includes a second region having a positive slope for informational components of an input signal so that informational components of the first frequency band signal cause the point operator to produce a modified signal having components that relate to the input signal according to the positive slope. The modified signal is then received by a synthesis filter (730), corresponding to the analysis filter, to produce a helper signal (704). The helper signal and the digitized image signal are then added to yield an enhanced digitized image signal (705).

摘要： A bandpass enhancement filter (10) has a pass-band that tracks changes in spatial frequency due to the use of a zooming process upon a digital image signal. The primary pass-band of the enhancement filter is derived from a combination of a plurality of secondary bandpass filter sections (30a-30d), each having a different frequency response and each responsive to a gain adjustment (34a-34d). A control signal (26) reflecting a particular zoom ratio is used in the adjustment of the gain applied to the filter sections, thereby proportioning the output of each filter section so that the combined output tracks the zooming process.

摘要： A transmisson device for transmitting a wanted signal (NS) modulated on a carrier (TS) has a band filter connected in the transmission path (2) of the transmission device (1) and tuned with the frequency (F(T)) of the carrier. An error signal circuit (9) influences the band filter, recognizing oscillations generated at the band filter whose amplitude remains below a set limit value (SW) set in the error signal circuit, and generating an error frequency signal (FS) representative of the frequency of occurrence of the recognized oscillation errors. A quality adjusting circuit (7) which adjusts the quality (G) of the band filter is connected to the band filter (5) and the error frequency signal (FS) is supplied to its adjusting input. When the error frequency signal is missing, a first filtering quality (GO) is adjusted at the band filter on the basis of a quality conversion characteristic (10), setting a band width (Bf18) at the band filter at least equal to the predetermined transmission band width for the wanted signal (NS) to be transmitted. When an upper value (FSn) of the error signal (FS) is generated for a determined error rate yet to be regulated, a second filtering quality (GM) is adjusted at the band filter on the basis of the same quality conversion characteristic (10), setting a determined voltage magnification of the carrier oscillation (TS) at the output of the band filter.

摘要： A contour emphasizing device for TV cameras wherein a level correction circuit is interposed to non-linearly process the video signals from a TV camera to send them to a contour emphasizing circuit.

摘要： A video signal is enhanced using a non-linear combination of left and right difference signals (L and R), constrained to be zero if either L or R is zero, using a minimum absolute value function.
