We discuss an algorithm that works with the concept of a reserved highlight region. It primarily addresses the problem of displaying legacy images calibrated for StandardDynamic Range displays onto displays having higher dynamic range, such as Megacontrast displays having standard brightness and bitdepth, as well as HighDynamic Range displays having increased brightness and bitdepth. The technique reserves headroom of the display range past maximum diffuse white for specular highlights and selfluminous objects. The paper discusses how to detect the specular highlights and light sources, how to construct a tonescale with reserved headroom, and different experiments conducted to learn how much of the dynamic range should be allocated for this upper luminance. |
