 Real5-OmniDocBench contains five challenging and representative photographic scenarios:
 * **Scanning**: Images captured by scanning devices, simulating flat, clean document scans.
 * **Curving**: Photos of documents with visible page curvatures, mimicking book spine or folding distortions.
+* **Skewing**: Documents photographed at an angle, resulting in perspective distortion.
 * **Screen-photo**: Photographs of screens displaying documents, introducing moiré patterns and reflections.
-* **Lighting-variation**: Images taken under varied lighting conditions, including shadows and glare.
-* **Skewing-variation**: Documents photographed at an angle, resulting in perspective distortion.
+* **Light-variation**: Images taken under varied lighting conditions, including shadows and glare.
 
 ### 2. Comprehensive Coverage
 For each scenario, the dataset contains **1,355 images**, corresponding exactly to the original pages in the OmniDocBench evaluation set. This enables direct, controlled comparison of model performance across different real-world conditions.
