摘要
文中设计、生成HDTV图像清晰度复合测试图。按在极坐标系建立的数学模型,由计算机逐像素编程计算、生成的该测试图,精度高,便于修改,已在定量测定数字图像清晰度中得到应用。
In this paper, we designed the composite lest pattern for testing the Definition of the HDTV Picture. After mathematical modelling in polar coordinate system, we computed some parameters of the test pattern. Then we got the pattern using the programmes in computer. The test pattern has high precision and we can modify it easily. Moreover we have already applied it in reality to test the definition.
