Abstract:
Head-mounted displays enable a user to view a complete environment as if he/she was there; providing an
immersive experience. However, the lighting in a full environment can vary significantly. Panoramic images
captured with conventional, Low Dynamic Range (LDR), imaging of scenes with a large range of lighting
conditions, can include areas of under- or over-exposed pixels. High Dynamic Range (HDR) imaging, on
the other hand, is able to capture the full range of detail in a scene. However, HMDs are not currently HDR
and thus the HDR panorama needs to be tone mapped before it can be displayed on the LDR HMD. While a
large number of tone mapping operators have been proposed in the last 25 years, these were not designed for
panoramic images, or for use with HMDs. This paper undertakes a two part subjective study to investigate
which of the current, state-of-the-art tone mappers is most suitable for use with HMDs.
