Tone Reproduction Accounting for Mesopic Vision

- Changing hue due to overall Luminance condition -

Abstract

High dynamic range images (HDRI) have been employed in computer graphics to enhance visual quality since they provide more accurate real world measurements of light. Displaying HDRI in typical displays, however, requires tone mapping as the dynamic range between the image and the device can differ significantly. Although several algorithms were proposed, most of them do not account for proper human vision light response, such as mesopic vision. In short, mesopic vision relates how hue changes due the overall scene's luminance: blue-shift occurs in low-light conditions, making red intensities appear dim. This work proposes a novel tone reproduction technique to simulate mesopic vision using spectral-based HDR images.
