Title: Innovations of Chi-Hao Yang
Introduction
Chi-Hao Yang is a notable inventor based in San Jose, California. He has made significant contributions to the field of video technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
Chi-Hao Yang's latest patents include a Multi-standard video decoder and a Sharpness enhancement circuit for video signals. The Multi-standard video decoder is designed for decoding a composite video signal and includes an analog-to-digital converter (ADC), an input resampler, and a Y/C separator. This decoder effectively digitizes the composite video signal to generate ADC samples, which are then resampled to produce video samples. The Y/C separator plays a crucial role in separating these samples into luminance and chrominance components, with adjustable delay based on the video line duration.
The Sharpness enhancement circuit for video signals focuses on enhancing edges while minimizing undershoots and overshoots. This process involves generating a first signal indicative of detected edges by lowpass filtering the video signal. The first signal is processed with a non-linear transfer function to create a second signal that enhances edges dynamically based on the characteristics of the detected edges. This innovative approach results in an output signal that significantly improves video quality.
