Head-mounted display system and method for processing images
First Claim
1. A head-mounted display system comprising:
- display means freely detachable and attachable on a user'"'"'s head;
direction-detecting means for detecting the orientation of a user'"'"'s head in at least the horizontal direction, the direction-detecting means being disposed on the display means;
an image generator for generating an image in accordance with the orientation of the user'"'"'s head detected by the direction-detecting means;
displacement-calculating means for calculating displacement, the displacement being the difference between directional data of the current orientation of the user'"'"'s head detected by the direction-detecting means and directional data of the orientation of the user'"'"'s head detected a predetermined amount of time ago; and
image-processing means for sending an image generated by the image generator to the display means after shifting the image in at least the horizontal direction in accordance with the displacement calculated by the displacement-calculating means.

27. A method for processing an image of a head-mounted display system, comprising steps of:
-
detecting the orientation of the user'"'"'s head in at least the horizontal direction using direction-detecting means disposed on displaying means freely detachable and attachable on the user'"'"'s head;
generating an image in accordance with the orientation of the user'"'"'s head detected by the direction-detecting means;
calculating the displacement of the user'"'"'s head, the displacement being the difference between directional data of the current orientation of the user'"'"'s head detected by the direction-detecting means and directional data of the orientation of the user'"'"'s head detected a predetermined amount of time ago;
processing the image such that the spatial position of displaying the generated image on the display means is shifted in at least the horizontal direction in accordance with the calculated displacement. - View Dependent Claims (28)
