    • A contour restoration apparatus has a plurality of delay circuits connected in series. Maximum and minimum value detection circuits detect maximum and minimum values among an input video signal and output signals of the delay circuits. A mean value circuit is used to calculate a mean value of the of the maximum and minimum values. The mean value is subtracted from a delayed signal having a delay time of one-half of a delay time obtained from all the delay circuits. An adder is used to add the result of the subtraction to the delayed signal. A non-linear processing circuit processes the output of said adder and the maximum and minimum values. The non-linear circuit outputs the output signal of the adder, if the output signal of said adder is between the maximum value and the minimum value. A contour extraction circuit multiplies a signal located centrally among the input video signal, the output signals and the signals located before and after the input signal with a predetermined coefficient. An adder adds the multiplied signals. Another adder adds the result of multiplied signal and the centrally located signal. A contour amplitude circuit detects a difference between the maximum and minimum values and outputs a coefficient determined according to the difference detected. A mixer mixes the output of the non-linear processing circuit and the output of the another adder.
    • 轮廓恢复装置具有串联连接的多个延迟电路。 最大值和最小值检测电路检测输入视频信号和延迟电路的输出信号之间的最大值和最小值。 平均值电路用于计算最大值和最小值的平均值。 从具有从所有延迟电路获得的延迟时间的二分之一的延迟时间的延迟信号中减去平均值。 加法器用于将减法的结果加到延迟信号上。 非线性处理电路处理所述加法器的输出和最大值和最小值。 如果所述加法器的输出信号在最大值和最小值之间,则非线性电路输出加法器的输出信号。 轮廓提取电路将位于输入视频信号之间的中心的信号,输出信号和位于输入信号之前和之后的信号以预定系数相乘。 加法器加上相乘的信号。 另一个加法器将乘法信号的结果和位于中心的信号相加。 轮廓振幅电路检测最大值和最小值之间的差异,并输出根据检测到的差异确定的系数。 混频器混合非线性处理电路的输出和另一加法器的输出。
