    摘要: There is provided a detection circuit for TV receiver which includes a frame comb filter and a field comb filter and which generates a luminance signal or a chrominance signal by effecting addition or subtraction upon video signals of two frames adjoining each other included in the received TV signal. This detection circuit includes a synchronization separation circuit, an APC circuit, a frequency division circuit connected to the APC circuit, and a comparator circuit connected to the frequency division circuit. The frequency of the chrominance subcarrier signal is demultiplied by the frequency division circuit. The phase of the chrominance subcarrier signal thus frequency-divided is compared with the phase of the synchronizing signal separated by the synchronizing separation circuit. It is thus judged whether the received TV signal is a standard TV signal or a nonstandard TV signal.

    摘要: A television signal processing circuit which separates a television signal into a luminance signal and a chrominance signal or interpolates the scanning lines of the television signal by using a video memory such as a frame memory or a field memory. The circuit determines whether the television signal to be treated is a standard television signal or a non-standard television signal. Depending upon this determination, the signal processing circuit changes its operation mode so that it operates properly even in case the television signal is different from the standard television signal and contains jitter in the time axis like the signal from a VTR. When the television signal is a non-standard television signal, the processing circuit without the video memory operates.

    摘要: A color television signal processing circuit receives an input signal of a composite color television signal in the form of superimposition of a chrominance carrier signal on a luminance signal, separates the chrominance carrier signal and the luminance signal, and doubles the number of scanning lines of the chrominance signal or the luminance signal as compared to the number of scanning lines of the composite color television signal. A separation circuit separates the chrominance carrier signal and the luminance signal on the basis of a difference signal of the composite color television signal between adjacent frames or adjacent fields. A scanning line interpolation circuit doubles the number of scanning lines of at least the luminance signal delivered out of the separation circuit on the basis of an interpolation scanning signal derived from a signal indicative of scanning lines for the adjacent preceding field.

    摘要: The present invention provides a movement correction frame count transformation apparatus for carrying out frame count transformation processing on a picture signal. In the apparatus, an input picture signal (S1) of interlaced scanning is converted into a signal (S2) of sequential scanning by an IP conversion unit (1). A movement detecting unit (3) detects movement detection signals (MD1 and MD2). A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel. An MC interpolation frame signal generating unit (7) generates an interpolation frame in movement correction processing carried out by a median filter in order to produce a signal (S4) of sequential scanning as a result of frame count transformation based on movement correction.
