Novel methods and systems for inverse tone mapping are disclosed. A scene can be analyzed to obtain highlight detection from bright light sources and specular reflections. An inverse tone mapping curve can be calculated based on the lower dynamic range and higher dynamic range displays. Multi-scale filtering can be applied to reduce noise or artifacts.
