平板显示器运动图像清晰度客观测试技术研究

Research on Objective Measurement Technique of Flat Panel Display Motion Picture Resolution

提出了一种基于高速相机和时域空域解耦人眼视觉系统模型的新型运动图像清晰度客观测试方法,具有采用静态、动态一致的显示线作为评价参数,以及更完善的人眼视觉系统算法,基于调制度的客观测试能力等优点。采用高速相机、瞬态光度计、视频发生器实现了测试系统的原理性试验装置,并研制了软件验证算法。核心算法与测试序列已得到国家发明专利授权并得到系统实验验证。

Novel subjective measurement technique of fiat panel display motion picture resolution is proposed in this paper. This method takes advanta- ges of novel time and spatial domain decomposes haman vision system algorithm, and ＂resolution line＂ based specification system which is coincidence between motion picture and static picture. Also, modulation depth based threat hold judgment algorithm is utilized. A set of test apparatus is setup in this paper, which includes high speed camera, colorimeter with analog output and video pattern generator. The core design is granted Chinese Invention Pa- tent and demonstrated by system field test.
