摘要： Motion vectors resulting from block matching are corrected for periodic structures by taking a more reliable vector from an edge of a moving object containing the periodic structure. This is done by calculating and comparing different error combinations to identify periodic structures and replacing a current motion vector with one of an adjacent pixel block either from the block to the left or from the block above, which ever yields the smaller error in the current block, or by taking a combination (e.g., mean) of both vectors. Advantageously, artifacts such as phase reversal of information in interpolated fields due to the presence of an erroneous vector in a periodic structure are reduced and very little additional processing is required after the block matching itself.
摘要翻译：通过从包含周期性结构的运动对象的边缘获取更可靠的向量来校正来自块匹配的运动向量，以对于周期性结构进行校正。这可以通过计算和比较不同的误差组合来识别周期性结构，并用一个相邻像素块（从块向左）或从上面的块替换当前的运动矢量，从而产生当前块中的较小误差，或通过两个载体的组合（例如，平均值）。有利的是，由于在周期性结构中存在错误的向量而导致内插场中的信息的相位反转的伪像被减少，并且在块匹配本身之后需要很少的附加处理。

摘要： A video display driver applies a video signal to pixels arranged in columns and rows of a liquid crystal display. A given column or data line driver includes a field effect transistor that operates as a comparator. The comparator is responsive to the video signal and to a reference ramp signal. A triggering voltage of the comparator is automatically and periodically adjusted. A drain voltage of the transistor that is equal to a threshold voltage of the transistor is developed in a stray capacitance, during the automatic adjustment period. A pulse signal, is coupled via the capacitance to increase the drain voltage. The drain voltage is applied to a gate electrode of a second field effect transistor that applies a data ramp voltage to the pixels. The pulse signal provides a small amount of drive in the second transistor.

摘要： A liquid crystal display includes pixels that are arranged in columns and rows. Data line drivers responsive to a video signal develop output signals in data lines that correspond with the columns, respectively. An adjustment data line driver is provided. The adjustment data line driver is responsive to a reference DC constant signal at a mid-range of the video signal.

摘要： In a television receiver, a microprocessor controls a horizontal deflection circuit which is coupled to run mode power supply to define a standby operating mode and a run operating mode. The microprocessor has a power-up reset input terminal which initializes operation upon application of AC mains power. The run mode power supply is coupled to at least one load which is subject to overcurrent or overvoltage faults. A fault detection circuit detects fault conditions in the run mode power supply loads such as overvoltage or overcurrent and anomalous vertical deflection current. Upon fault detection the fault detection circuit triggers a power up reset circuit which applies a momentary reset pulse to the power-up reset input of the microprocessor. Upon receipt of the reset pulse, the microprocessor controls the horizontal deflection circuit to place the run mode power supply in the standby operating mode. Thus power is removed from the run mode load subject to the overvoltage or overcurrent or anomalous condition, and the television receiver assumes a standby condition.

摘要： A noisy input signal x is filtered with a restoration filter of median type to generate a filtered input signal y. The sum of the absolute differences between filtered and unfiltered signal is calculated for each position of a sliding window within the input signal representing a local estimate of the noise, and is combined with a global measure of the input signal noise to compute two coefficients a and b which are respectively applied to the unfiltered and filtered signal to generate the output signal z=a*x+b*y which is both globally and locally adapted to the structure of displayed images. Advantageously different kinds of filters operate in parallel, whereby the kind of filter elected is locally adapted to the picture activity.

摘要： Extra lines (Yout) for display be progressive scanning are obtained by adaptive interpolation from the original (interlaced) lines. The original lines are left untouched. Each interpolated pixel is the result of a soft switch (456,461,462) between pure interframe interpolation (452), which is the more suitable for areas without moving detail, and interpolation (451) using the Diag-3W algorithm, which is the more suitable for moving areas. The soft switch coefficient (S) is calculated using a normalized comparison between two estimates (E.sub.v,E.sub.t) of the likely error resulting from each of the two kinds of interpolation. To limit the occurrence of wrong decisions due to noise or to certain structures in the picture, the decision is spread horizontally, vertically and temporally, but only over a very small area so that the decision remains local to the pixel (X) being interpolated.

摘要： A muting circuit for eliminating transient signals generated due to power supply "turn-on" and "turn-off" is presented. In one embodiment, a junction in a signal chain is AC shunted to ground independent of the DC status of the junction. This shunting is in response to a signal generated by a power supply controlling microprocessor when the microprocessor energizes or de-energizes the power supply for a portion of the signal chain coupling signal to the acted upon junction. In another embodiment, the junction is AC coupled to ground during turn-on through a diode in series with a capacitor with the diode first being forward biased and then reverse biased to remove the AC shunt. The biassing of the diode is accomplished by application of two different sources of voltage to respective electrodes of the diode.

摘要： In a vertical sawtooth generator of a vertical deflection circuit, a first comparator generates an output signal when a retrace portion of a sawtooth signal is at a first magnitude to initiate a vertical trace portion of the sawtooth signal. An amplifier responsive to the sawtooth signal generates a feedback current at a time that occurs more than one-half of the length of vertical trace portion after vertical trace is initiated. The feedback current is coupled to a capacitor to develop a capacitor voltage. The capacitor voltage is applied via a voltage-to-current converter to an integrating capacitor to develop in the integrating capacitor the trace portion of the sawtooth signal.

摘要： A television receiver includes a single tuner for tuning both television channels and broadcast FM stations. The tuner serves as the first conversion stage of a double conversion FM receiver, a separate mixer-oscillator converts the FM radio sound IF to 4.5 MHz for processing in the television receiver's sound channel. A single discriminator circuit is employed for tuning FM radio signals having a first deviation, such as broadcast FM radio signals, and FM signals having a second deviation (i.e., the television sound signals), and FM radio signals having a third deviation, such as signals of the National Weather Service. Circuitry for amplifying the output signal of the discriminator circuit exhibits a first gain, and a first volume control range when amplifying FM signals having the first deviation, exhibits a second gain and the first volume control range, when amplifying FM signals having the second deviation, and exhibits a second gain, and a second volume control range when amplifying FM signals having the third deviation.
