摘要： A movement detector is included in television signal processing apparatus in order to improve the performance of the apparatus. The detector evaluates an absolute frame difference signal on a sample by sample basis and, after comparison with a threshold level signal in order to remove the effects of noise is fed to an isolated point removal circuit where samples deemed to indicate movement are compared with surrounding samples and if identified as isolated are ignored. Adaptive control is provided if the threshold, the isolated point removal circuit and a quantizer circuit for non-linearly altering the frame difference signal.

摘要： image movement correction is provided for example in a field conversion television system by deriving simultaneously two fields of a selected number of lines from an original single field and vertically shifting one of the derived fields by 0.5 lines. A movement vector is determined (5) for each field and movement correction is performed based on a current field and a preceding field, in the case of a moving object in the image. If no moving object is present, linear approximation is employed to correct for motion caused by the field number conversion. Two memory systems (51 to 54 and 55 to 58) are provided for the two simultaneous fields and also selectively to obtain specific horizontal lines of the current and preceding fields, relative to both simultaneously derived fields. Ultimate selection of a field for display is based upon the detected movement vector.

摘要： A motion video signal (2000), especially a frame-skipped signal is interpolated by detecting motion vectors in a detector (15). A motion estimation circuit (16) computes a representative motion'vector which is used to control the interpolation within a storage and computation unit (100) in which several frames are stored in a buffer (11) and read out by a speed matching circuit (12) in accordance with a scanning speed signal (1012) from a control generator (10). A frame of the video signal is also stored in a frame memory (18) which is addressed by an address generator (17) under control of the representative motion vector from the estimation circuit (16) to introduce a corresponding shift and thereby effect motion adaptive interpolation. The control generator (10) also controls a change-over circuit (14) to select the signal from the frame memory (18) or as read out from the buffer (11). Various embodiments of the motion estimation circuit (16) are described. All implement the principle of modifying the representative vector in such a manner that its frame to frame variation is limited to a predetermined range. This avoids jerky interpolation.

摘要： Upon execution of the movement detection by way of a gradient method the leftward and rightward sampling differences AEL and AER at a change extremal value point are used to detect the respective movements in the vertical and horizontal directions. The movement amounts detected are selectively fetched. Upon addition/subtraction of the frame difference, the sign of sample is held until the positive or negative sign of the sample which is obtained from the result of comparison between the sampling difference values before and after the sample is changed. The accurate movement detection is performed by controlling the addition/subtraction in response to the holding signal.

摘要： A video signal interpolation includes a frame interpolation filter (402) which generates from a video input signal (Y) by interpolation from corresponding elements of immediately preceding and following fields, a frame interpolated output signal tending to exhibit motion artefacts. A second filter (430) provides a line interpolated signal having picture elements spatially and temporally coincident with corresponding elements of the frame interpolated signal and having a suppressed vertical detail component. A third filter (440) attenuates the vertical detail component of the frame interpolated signal. An output circuit (461, 450) combines the signals of the three filters to provide a frame interpolated video output signal (Yi) in which the vertical resolution of the video input signal (Yd) is preserved and motion artefacts characteristic of frame interpolation are attenuated. The interpolator of the invention is particularly suitable for providing the required interpolated video signal in progressive scan display systems in which a delayed and time-compressed video signal derived from a video input signal is displayed line-by-line alternatingly with an interpolated video signal obtained by interpolation from the input signal.

摘要： As the 8-bit input signal applied to a threshold device (50) reaches a first threshold level, the 1-bit output signal changes from a logical zero to a logical one. The 1-bit output signal is delayed by one system clock period and fed back. The delayed 1-bit output signal is combined (40) (e.g., merged or added) with the 8-bit input signal, and the resulting signal is applied to the threshold device to provide a hysteresis feature. Once the delayed 1-bit output signal becomes a logical one, the input signal has to drop below a second, lower threshold level before the 1-bit output signal can revert back to a logical zero, whereby a margin of noise immunity is provided.

摘要： A wideband video signal processing system includes a blanking interval signal conditioning circuit (14) with reduced parasitic capacitance. The circuit comprises an AC coupling capacitor (17) between the input and output of a video signal path, preferably between an input buffer amplifier (15) and an output buffer amplifier (19). A first keyed electronic switch (16) of the single pole, single throw type is coupled in series with the capacitor. A second keyed electronic switch (18) of the single pole, single throw type is coupled between the output of the capacitor and a reference voltage. The first and second switches are keyed to establi sh a fixed video signal reference value during image blanking intervals.
