Head-mounted display apparatus

Abstract

To provide a wearing-in head type indicating device which can effectively diminish power consumption without irksome operations. The wearing-in head type indicating device is provided with: a see-through image indicator 6 which sets an indicator frame within an indicatable range and indicates an image to make it overlapped with an external image within the indicator frame; angle speed sensors 81, 84 which are used to detect a tilt angle of observer's head; LCD driver 105 and a second CPU 112 which control to move the indicator frame to the corresponding amount of angle to the detected angle in the opposite tilt direction to the obsever's head regardless of the tilt of observer's head in order to make the virtual position constant from the observor's viewpoint; and first CPU 111 which automatically controls to switch to a low power consumption mode when the indicator frame deviates from the indicatable region to be not indicated within the predetermined time.

Description

technical field [0001] The present invention relates to a head-mounted display device, and more particularly, to a head-mounted display device that displays and observes images while being worn on the head. Background technique [0002] Conventionally known display devices that are mounted on the head to observe images include, for example, an HMD (head-mounted display) and a HUD (head-up display). [0003] As such a display device, for example, the device described in Japanese Patent Application Laid-Open No. 2003-248194 can be cited. The image display device described in this publication projects an image arranged on a glasses-shaped frame onto a holographic optical element as a combiner, introduces the image reflected by the holographic optical element into the observer's eyes, and superimposes a virtual image of the image. displayed to the outside world. [0004] In addition, Japanese Patent Application Laid-Open No. 6-78247 describes a head-mounted display device that...

Problems solved by technology

However, it would be troublesome to take off the glasses before each action like taking off the glasses, for example

Also, it is cumbersome to remove or power off the display unit during normal operations

[0012] In addition, in the conventional display device, when the power consumption needs to be reduced, it is also necessary to cut off the power supply (for example), but in this case, it is still very troublesome to perform the operation of turning off the power supply reliably.

On the other hand, the technology of reducing power consumption (i.e., the technology of controlling the power supply when keyboard input and other operations are not performed within a specified period of time) adopted in the above-mentioned personal computer is not necessarily applicable to information display devices that do not require human input operations, etc.
