Document Type and Number:
WIPO Patent Application WO/2017/061488
Kind Code:
A1
Abstract:
In this head-mounted display including a light-emitting unit for identifying an attitude, the luminance of the light-emitting unit is made controllable without providing a separate device for measuring the luminance of the light-emitting unit. On the basis of an image for attitude identification that is captured by a camera and includes an image of the light-emitting unit that emits light with luminance corresponding to a drive current, an attitude identifying unit (62) identifies the attitude of the HMD including the light-emitting unit. A luminance information identifying unit (64) identifies information indicating the luminance of the light-emitting unit on the basis of an image for luminance identification that is captured by the camera that captures the image for attitude identification and includes an image of the light-emitting unit. A drive current control unit (66) controls the drive current of the light-emitting unit on the basis of the identified information indicating the luminance of the light-emitting unit.
