数码相机分辨率测试卡 (QA-70D)

Wedges of 4 dark lines converge to allow measurement of digital camera resolution up to 8000 TVL (TVL is also known as "lines per picture height", simple as lines, lines of resolution or TV lines).

Measurements to 8000 lines can be performed in the center and all 4 corners (of both 4:3 and 16:9 ratios) as well as a few additional spots. The chart is arrayed for both 16:9 and 4:3 ratios.
