Product Summary
The ML87V21071 is a OKI semiconductor. It is a video signal noise reduction IC with a built-in frame memory. The ML87V21071 which comprises a frame memory and signal processing and memory control logic circuits, has achieved motion-adaptive 3D noise reduction. To perform noise reduction with afterimage suppression, the ML87V21071 also enables noise reduction using the edge-adaptive 2D noise reduction filter. Each noise reduction function allows setting an automatic mode. In automatic mode of the ML87V21071, noise of a vertical blanking period and a valid data period is detected to reduce noise according to the noise status from which the noise reduction setting value is detected.
