    • A signal processing apparatus and a control method thereof are provided. The signal processing apparatus includes: a comb filter which divides a luminance signal and a chrominance signal from an input video signal and outputs a luminance level of the luminance signal and a color level of the chrominance signal; an output unit which outputs one of the luminance level output by the comb filter and a blurred luminance level obtained by blurring the luminance level; and a controller which determines whether the luminance level output by the comb filter includes the color level, and controls the output unit to output the blurred luminance level if the color level is included in the luminance level, and output the luminance level if the color level is not included therein.
    • 提供了一种信号处理装置及其控制方法。 信号处理装置包括:梳状滤波器,其从输入视频信号中分离亮度信号和色度信号,并输出亮度信号的亮度级和色度信号的色度; 输出单元,其输出由梳状滤波器输出的亮度级中的一个和通过模糊亮度水平获得的模糊亮度级; 以及控制器,其确定由梳状滤波器输出的亮度级是否包括颜色电平,并且如果色度包括在亮度级中,则控制输出单元输出模糊亮度级,并且如果色彩级别 不包括在内。

    • A device and a method for generating a variable slice reference level. At least two variable slice reference levels used for slicing VBI data are generated. The device includes a high/low average value generator, a reference value detector, and a slice level generator. The high/low average value generator generates an average high value and an average low value of the VBI data using a plurality of window signals. The reference value detector generates an average reference value of the VBI data using the window signals. The slice level generator outputs a high slice level and a low slice level using the average high value, the average low value, the average reference value, and a tuned factor.
    • 一种用于生成可变切片参考水平的装置和方法。 生成用于切片VBI数据的至少两个可变切片参考等级。 该装置包括高/低平均值发生器,参考值检测器和限幅电平发生器。 高/低平均值发生器使用多个窗口信号产生VBI数据的平均高值和平均低值。 参考值检测器使用窗口信号产生VBI数据的平均参考值。 限幅电平发生器使用平均高值,平均低值,平均参考值和调谐因子输出高限幅电平和低限幅电平。
