Enhanced Digital Camera Resolution Chart
Based on ISO-12233, the QA-77 has all of the original features as the QA-72 plus several new ones, such as; Star Sector target; 5° slant bar; 5° dark gray square for SFR analysis as well as a greater resolution range, from 100 - 4000 Line Width / Pixel Height and hyperbolic wedges.

高效的數(shù)碼相機解析度卡

數(shù)碼相機解析度卡是基于ISO-12233標準卡出現(xiàn)的（13A/ISO照相機解析度卡），它的特征擴充除了把他的應(yīng)用價值從2000 1/PH挺高到4000 1/PH，而且與SFR評估方法相比較，他把誤差降低了24％。它與SFR圖像評估一樣能與傾斜邊緣分析工具軟件一起運行。
