Abstract(in English) To display spherical high dynamic range (HDR) images in offline telepresence systems that provide users with sense of looking around the scene, it is required to compress dynamic range appropriately using tonemapping techniques. The goal of the this study is investigation of appropriate tonemapping method for a telepresence using aerial spherical HDR images. In experiments, we compared various tonemapping methods: usual low dynamic range (LDR) imaging technique, a widely-used tonemapping method by Reinhard, et al, a method using segmentation, and a view-direction dependent adaptive tonemapping method. We finally give discussion through the evaluation results.
