彩色清晰度测试卡描述:
这个测试卡是专为研究彩色清晰度。
用于检查彩色清晰度
不同区域可测试分辨率及抗锯齿性能
每个区块分为四个象限,包含垂直、水平和对角分辨率
不仅水平和垂直,也可以测试对焦和抗锯齿效果。
18个象限的空间频率扫描从200到1000 TV LPPH,若只拍摄测试卡的一半则是100 - 500 TV LPPH
·This chart is designed for examining chrominance resolution.
·Used to examine chrominance resolution
·Segmented zone plates reveal diagonal resolution and aliasing artifacts
·Each zone plate is divided into four quadrants, containing vertical, horizontal and diagonal components
·The Wringer reveals diagonal resolution and aliasing artefacts that are not typically seen using vertical and horizontal wedges.
·The 18 zone plate quadrants have spatial frequency sweeps from 200 to 1000 TV LPPH – framing to half the chart’s width yields 100 to 500 TV LPPH
