Abstract
This paper proposes a foveated brightness control (FBC) technology for VR applications. FBC technology reduces brightness of the unfoveated area. Through subjective experiments, threshold values of lightness reduction ratio (LRR) depending on four different gaze points are found where people cannot recognize the difference while the brightness of unfoveated area is reduced. It is found that the LRR threshold for gazing up is lower than that for gazing down and the LRR threshold for gazing left or right depends on dominant eye.
