资 源 简 介
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, 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. The ML87V21071 also has a cross-color cancellation function that uses the motion-adaptive 3D comb filter method that removes cross colors occurring at two-dimensional YC separation in the NTSC/PAL system. Since the same format as the input can be selected for output, noise reduction can easily be achieved by inserting the IC into the conventional system.
