在明亮的阳光下和昏暗的条件下看到的相同的物理场景对人眼来说并不相同。类似地,在8000 cd/m2高动态范围(HDR)显示器上显示的图像和在50 cd/m2峰值亮度影院屏幕中显示的图像在它们的外观上也显著不同。我们提出了一种亮度重定向方法,改变感知的对比度和颜色的图像,以匹配不同亮度水平下的外观。该方法依赖于匹配对比度的心理物理模型,视杆对视觉的贡献模型以及我们自己的测量。重定向涉及找到最佳色调曲线、空间对比度处理以及色调和饱和度偏移的建模。这使我们能够在明亮的条件下可靠地模拟夜视,或者补偿在较暗的显示器上显示的明亮图像,以便它显示否则不可见的细节和颜色。
The same physical scene seen in bright sunlight and in dusky conditions does not appear identical to the human eye. Similarly, images shown on an 8000 cd/m2 high-dynamic-range (HDR) display and in a 50 cd/m2 peak luminance cinema screen also differ significantly in their appearance. We propose a luminance retargeting method that alters the perceived contrast and colors of an image to match the appearance under different luminance levels. The method relies on psychophysical models of matching contrast, models of rod-contribution to vision, and our own measurements. The retargeting involves finding an optimal tone-curve, spatial contrast processing, and modeling of hue and saturation shifts. This lets us reliably simulate night vision in bright conditions, or compensate for a bright image shown on a darker display so that it reveals details and colors that would otherwise be invisible.
