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： 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.
