Sineimage / 3nh YE0276 Color Spilled Coins (Dead Leaves) Test Chart for measuring camera texture sharpness
| Model | YE0276 |
| Type | Reflective |
| Format | Custom Designs |
| Ratio | 1:1 |
The Color Spilled Coins chart (a variant of the Dead Leaves chart) for measuring texture sharpness has several advantages over older Dead Leaves charts. Key features:
- The Scattered Coins pattern in the central region is almost perfectly scale-invariant (unlike conventional dead leaves charts), enhancing the accuracy and robustness of MTF measurements so they correlate well with other methods (such as the slanted-edge) for RAW images (which have no nonuniform or nonlinear processing).
- Maximum contrast range is 3:1, as called for in the CPIQ Phase 3 draft Texture Blur Metric draft specification.
- It is more uniform, i.e., is more shift-invariant than other Dead Leaves charts.
- It contains slanted edges (2:1 and 4:1 contrast) for convenient comparisons with the dead leaves pattern.
- The gray area to the left and right of the dead leaves pattern has the same mean density as the dead leaves pattern, allowing it to be used for effective noise PSD removal using the McElvain et. al. technique.
- Registration marks and 16 grayscale patches are included. The linear levels used to create the grayscale patches are 0 through 255 in steps of 17 (same as the Siemens Star chart in the draft of the upcoming ISO 12233 standard).
