This paper introduces a psychophysical experiment to investigate the image quality trade‐off relationship between peak luminance and the chromaticity area of the color gamut of a display device and models to predict equivalent image quality based on the experimental results. Our experimental results confirmed the hypothesis that the peak luminance required to maintain equivalent image quality tends to decrease as the color gamut area expands. At the same time, the relationship between peak luminance and color gamut strongly depends on image content. Based on the experimental results, two models are suggested. These models show good performance in terms of predicting the required luminance levels for given color gamut areas. Notably, the model built using an observer‐chosen region of interest (ROI) in an image slightly outperforms the model generated without this information.

峰值亮度和色度色域之间的图像质量等效

本文介绍了一项心理物理实验，以研究峰值亮度与显示设备色域的色度区域之间的图像质量折衷关系，并根据实验结果进行建模以预测等效图像质量。我们的实验结果证实了这样的假设：随着色域范围的扩大，维持等效图像质量所需的峰值亮度趋于降低。同时，峰值亮度和色域之间的关系在很大程度上取决于图像内容。根据实验结果，提出了两种模型。这些模型在预测给定色域区域所需的亮度水平方面显示出良好的性能。值得注意的是
