    • A video signal processing apparatus for processing a video signal comprises a receive unit (101, 103, 105) which receives the video signal comprising a sequence of pictures. A processing unit (107) applies a picture noise changing algorithm to the sequence of pictures and a variation unit (113) varies a spatial noise reduction setting for the picture noise changing algorithm between at least some consecutive pictures of the sequence of pictures in response to a predetermined variation rule. Specifically a set of picture manipulation processes (203, 205) with different spatial noise reduction characteristics may be provided and the variation unit (113) may select different picture manipulation processes in consecutive pictures. The approach may introduce high frequency noise flickering which is less perceptible to a viewer thereby reducing the perceived noise. The invention may in particular be applied to upconverted high picture rate video signals for hold type displays, such as Liquid Crystal Displays displays.
    • 用于处理视频信号的视频信号处理装置包括接收包含一系列图像的视频信号的接收单元(101,103,105)。 处理单元(107)对图像序列应用图像噪声改变算法,并且变化单元(113)响应于图像序列的至少一些连续图像而改变图像噪声改变算法的空间噪声降低设置 预定的变化规则。 特别地,可以提供具有不同空间噪声降低特性的一组图像处理过程(203,205),并且变化单元(113)可以在连续图像中选择不同的图像处理过程。 该方法可能引入高频噪声闪烁,其对于观看者不太可感知,从而减少感知到的噪声。 本发明可以特别地应用于用于诸如液晶显示器显示器的保持型显示器的上变频高速率视频信号。
