Abstract
In the last years, High Dynamic Range (HDR) has been improved enormously. The capability of cameras and displays to reproduce small differences in luminance levels is constantly growing. However, we are still dealing with the limitations of the human visual system (HVS) known as the simultaneous contrast range (SCR). Compared to earlier studies, this paper focus on real world scenarios for evaluating the SCR. In natural images bright highlights, especially in HDR, can limit the eyes’ sensitivity to detect small differences in the surrounding dark areas.
