Creative Intent Based Ambient Compensation for HDR10+ Content Using Metadata

The paper proposes a high dynamic range (HDR) tone mastering system which dynamically modified the picture appearance based on creative intent metadata to preserve content providers' creative intent in different ambient light levels/ranges. Luminance percentile information based creative intent metadata is used to compensate for imagery degradation caused by ambient light. Multiple sections of tone mapping curves with multiple adjustment points along explicit Bezier curve is modified for better tone mapping curve control. Simulation results show that the proposed method can adapt to both ambient light levels and the scene content to keep the creative intent in different ambient conditions.
