Tone Mapping is the problem of compressing the range of a High-Dynamic Range image so that it can be displayed in a Low-Dynamic Range screen, without losing or introducing novel details: The final image should produce in the observer a sensation as close as possible to the perception produced by the real-world scene. We propose a tone mapping operator with two stages. The first stage is a global method that implements visual adaptation, based on experiments on human perception, in particular we point out the importance of cone saturation. The second stage performs local contrast enhancement, based on a variational model inspired by color vision phenomenology. We evaluate this method with a metric validated by psychophysical experiments and, in terms of this metric, our method compares very well with the state of the art.
色调映射是将高动态范围图像的范围压缩到可以在低动态范围屏幕上显示的问题，同时不丢失或引入新的细节：最终的图像应该在观察者中产生尽可能接近真实世界场景产生的感知。我们提出了一种具有两个阶段的色调映射算子。第一阶段是一种全局方法，基于人类感知的实验，实现视觉适应，特别是我们指出了锥体饱和的重要性。第二阶段基于受颜色视觉现象学启发的变分模型进行局部对比度增强。我们使用通过心理物理实验验证的度量来评估该方法，根据该度量，我们的方法与最新技术相比非常出色。
