    • The method detects motion of video signal which prevents the error due to the time delay of the logic circuits. The mothology is implemented using an A/D converter (11) for the conversion of the analog brightness signal into the digital form, a line memory (12) for the storage of the digital brightness signal of the previous line, a EPROM (13) of which lower addresses are connected to the brightness signal of the line memory and of which high addresses are connected to that of the A/D converter and in which the compensation table is stored in the formation of 1 to n-th order curve.
    • 该方法检测视频信号的运动,防止由逻辑电路的时间延迟引起的误差。 使用用于将模拟亮度信号转换为数字形式的A / D转换器(11)来实现该方法,用于存储前一行的数字亮度信号的行存储器(12),EPROM(13) 其中较低地址连接到行存储器的亮度信号,并且其高地址连接到A / D转换器的亮度信号,并且其中以形成1至n阶曲线存储补偿表。
