A Motion-Adaptive High-Definition Converter for NTSC Color TV Signals
In a conventional NTSC monitor, such impairments as cross-color, cross-luminance, line flicker, and line crawl limit both picture quality and resolution. A newly developed high-resolution converter removes impairments caused by composite, interlaced scanning signals. It includes two new processing circuits. The input NTSC signal is decoded into component signals by a new motion-adaptive YC separator. Then, the component signals are converted into a sequential scanning format by a new motion-adaptive scan line interpolator. By utilizing these two kinds of motion-adaptive processing, the impairments mentioned above are reduced considerably.
