摘　　要：给出了设计、生成的UHDTV4K复合测试图,阐述了其应用;导出了测试图同心度、重显率和清晰度等测试信号单元的数学模型,并逐像素计算生成;设计了固有分辨力显示屏分辨力观测信号;引入了色域和色度视角主观评价信号;集成了彩条和灰阶等多种观测信号。This paper presentsthe design and generation ofa UHDTV^k composite test pattern and explains its applications. A mathematical model to create the signals that test concentricity, reproduction ratio and definition etc. was developed and implemented pixel by pixel in the test pattern. A subjective test signal for inherent resolution display was also included. Gamut and chroma vie- wing angle tests were integrated, as were several other subjective test signals such as a color bar and gray steps.
