Title: Huan-Pin Tseng: Innovator in Audio and Image Processing Technologies

Introduction

Huan-Pin Tseng is a notable inventor based in Hsinchu, Taiwan. He has made significant contributions to the fields of audio and image processing, holding a total of 5 patents. His innovative work has impacted various technologies, particularly in television systems and image processing devices.

Latest Patents

One of Huan-Pin Tseng's latest patents is a method and apparatus for automatically selecting the audio format for the output signal of a tuner in a television system. This method involves configuring a SAW filter to a bandwidth of 5.5 MHz for filtering the IF signal to generate CVBS and SSIF signals. Band-pass filters are then used to detect the back porch of the CVBS signal, determining the signal amplitude at specific frequencies. The process includes assigning a bandwidth of 4.5 MHz to the SAW filter for filtering the intermediate frequency signal to regenerate the CVBS signal based on amplitude comparisons. Additionally, a video decoder decodes the CVBS signal to determine the video format, while an audio decoder decodes the SSIF signal to identify the audio format.

Another significant patent by Tseng is an image processing device and method aimed at reducing color artifacts. This invention includes a smooth unit that performs operations on color signals corresponding to pixels and adjacent pixels. A level shifter then adjusts the smooth color signal, and a color strength unit calculates a color strength indicator. The gray level decision unit determines whether a pixel is in a gray level region, leading to adjustments in the smooth and level-shifted color signals to generate an output color signal.
