Head-mounted display apparatus
First Claim
1. A head-mounted display apparatus comprising:
- an angle detector to detect the tilting angle of the head of an observer;
a display portion to display a predetermined image in such a manner that the predetermined image is superimposed on an image of an external environment, the display portion being changed from a display-state of the predetermined image to a non-display-state thereof and vice-versa, corresponding to the tilting angle of the observer'"'"'s head detected by the angle detector; and
a controller to control the display portion in such a manner that, in the case in which the non-display state of the display portion continues for not less than a predetermined time-period, the non-display state is continuously kept, even if the tilting angle of the head, thereafter, gets to have a value corresponding to the display-state thereafter.

Abstract
A head-mounted display apparatus comprises a see-through image display portion for setting a display frame in a display-capable range, and displaying an image in such a manner that the image is superimposed on an image of the external environment in the display frame, an angular velocity sensor for detecting the tilting angle of the head of an observer; an LCD driver, a second CPU and the like which control the display frame to move in an amount corresponding to the angle detected by the angle detection means in the direction opposite to the tilting direction of the observer'"'"'s head, whereby the position of a virtual image, observed by the observer, is kept substantially constant, irrespective of the tilting of the observer'"'"'s head, and first CPU which controls the apparatus so that the mode of the apparatus is automatically changed to a low consumption power mode.
