Abstract
A head-mounted display for displaying an image that matches a viewer's head movement has a head tracker for detecting the viewer's head movement, an eye tracker for detecting the viewer's eye movement, and an adaptive filter for adaptively filtering the output of the head tracker in accordance with the output of the head tracker and the output of the eye tracker, and when tracker, and when the viewer is watching a particular object in the displayed image, the adaptive filter is set as a low-pass filter, and this and the output gain of the head tracker is lowered; in other cases, the adaptive filter is set as an all-pass filter, and this prevents minute shaking of the head from being reflected on the displayed image, while retaining image display response to head motion, and furthermore, this serves to keep the particular object from being shifted outside the field of view.
