Title: HEAD-MOUNTED IMAGE DISPLAY DEVICE
Abstract:
Provided is a head-mounted image display device which allows remaining battery capacity to be readily recognized by the user and that allows extended operation time. This head-mounted image display device is provided with: an image display unit composed of a display optical system for emitting image light, an ocular optical system for projecting image light to an eye of a user, and a support section for supporting the display optical system and the ocular optical system; a control unit having a battery, a control section, a storage section, and a communication section; and a holding member for holding the image display unit and the control unit on the head of the user. The control unit furthermore includes a remaining battery capacity detection section for detecting remaining battery capacity, the remaining battery capacity detection section transmits a first battery-capacity-low signal when the remaining battery capacity is equal to or less than a predetermined first assessment level, the control section receives the first battery-capacity-low signal and changes the image light emitted from the display optical system to an image light corresponding to a predetermined warning display mode.
