Key Features
An 18% gray background provides standardized reflectance for consistent tests. Corner markers enable automatic software identification and repeatable test-region positioning. Sixteen grayscale patches support linearization calibration and accurate texture-response calculations. Four slanted edges at the top, bottom, left and right have different modulation levels, allowing comparison of texture MTF and slanted-edge MTF. The central dead-leaves pattern detects and evaluates texture-detail loss. Yanding RIQA Camera software provides automated measurement and analysis.
