    • The present invention relates to a video signal processing apparatus for outputting an inputted video signal after subjecting the video signal to time axis correction, particularly to a video signal processing apparatus preferable in the case of subjecting the video signal to image compression. In the case in which a nonstandard signal is inputted to an image compression circuit of an MPEG2 encoder or the like, a drawback of freezing image or generating block noise or the like is resolved. A time axis correcting circuit stores an input signal to a memory and reads the input signal at a timing delayed from V synchronization of the input signal by a predetermined time period. For that purpose, a read synchronizing signal generator is reset at respective input field. A reset position is set to a position preceding the read V synchronization position by 3H through 10H. It is detected whether the input signal is a non-interlace signal or a field length thereof is deviated from a standard value and in these cases, odd/even order or synchronization timing of a synchronizing signal is corrected. Further, when the input signal is a nonstandard signal, the input signal is outputted without passing through the image compression circuit by a changeover switch.
    • 视频信号处理装置本发明涉及一种视频信号处理装置,用于在对视频信号进行时间轴校正之后输出输入的视频信号,特别涉及在对视频信号进行图像压缩的情况下优选的视频信号处理装置。 在将非标准信号输入到MPEG2编码器等的图像压缩电路的情况下,解决图像冻结或产生块噪声等的缺陷。 时间轴校正电路将输入信号存储到存储器,并且以从输入信号的V同步延迟预定时间段的定时读取输入信号。 为此,读取同步信号发生器在相应的输入场复位。 复位位置被设定为读取V同步位置之前的位置3H到10H。 检测输入信号是不是隔行扫描信号还是其场长偏离标准值,在这些情况下,校正同步信号的奇数/偶数阶或同步定时。 此外,当输入信号是非标准信号时,输入信号不通过图像压缩电路通过转换开关输出。

    • A color picture signal processing circuit, a filter circuit and a luminance/carrier chrominance signal separation circuit implemented by employing the filter circuit. The circuit processing signal includes an adaptive-type (C) comb line filter through which the luminance signal is caused to pass. The output of the filter undergoes amplitude limitation in a limiter circuit, the output of which is subtracted from the original luminance signal. The carrier chrominance signal is added to the luminance signal to obtain a composite picture signal. The filter circuit is comprised of a pulse pattern suppressing circuit including a decision circuit for deciding which of positive and negative patterns the three adjacent data form constitute, a positive pulse pattern suppressing circuit, a negative pulse pattern suppressing circuit and a circuit selecting for either one of the output signal of the positive and negative pulse pattern suppressing circuits in accordance with the result of decision made by the decision circuit.
