| 英文摘要 | The visibility of Liquid Crystal Display (LCD) decreasing significantly while displaying motion picture, and how to evaluate Motion Picture Resolution of digital television has become a key concern. Motion picture resolution is a very important parameter for the evaluation of LCD and could be evaluated with smearing time according to national standards of PRC issued in 2006. Smearing time of LCD was measured using simulation method and SSPD pursuit tracking system. Simulation method was improved by introducing flash spectroradiometer and color alternate patterns. Camera pursuit tracking measurement system was established and SSPD was used instead of CCD. Results of experiments indicate that both black white pattern and color pattern could be measured effectively using these two improved methods and the camera pursuit tracking system's measurement resolution of smearing time could reach 0.3ms. |
