+ ## Introduction
7
+
8
+ Recent advancements in multimodal large language models have significantly improved document understanding by integrating textual and visual information. However, in real-world scenarios—especially under conditions of visual degradation—existing models often fall short. They struggle to accurately perceive and handle visual ambiguities, leading to an overreliance on linguistic priors and misaligned visual-textual reasoning. This challenge in recognizing uncertainty frequently results in hallucinated content, particularly when providing precise answers is infeasible.
9
+
10
+ To better illustrate and address this critical problem, we propose KIE-HVQA, the first dedicated benchmark designed to evaluate OCR hallucination in degraded document understanding. KIE-HVQA encompasses test samples from identity cards and invoices, enhanced with simulated real-world degradations that compromise OCR reliability. This benchmark uniquely facilitates the assessment of models’ abilities to discern reliable visual information under degraded conditions and respond appropriately, thereby emphasizing the challenge of avoiding hallucination when faced with uncertain data.
