HEADMOUNT DISPLAY AND BRIGHTNESS ADJUSTMENT METHOD

摘要

A headmount display (100) for presenting video by blocking the outside world from the field of vision of a user when worn by the user, wherein an information presentation unit (130) presents audio and video information to the field of vision of the user. A video playback unit (190) plays video content. A camera (140) captures video of the outside world. A switching unit (115) causes the information presentation unit (130) to present by selectively switching between the video of the content and the video of the outside world. A gain adjustment unit (105) adjusts so as to gradually increase the brightness of the outside world video when the switching unit (115) switches from the content video to the outside world video.
