Claim Text:
1. An optical see-through head-mounted display device, comprising: a see-through lens comprising an augmented reality display region and an opacity filter, the opacity filter comprising a plurality of pixels, each pixel is controllable to adjust an opacity of the pixel, and the augmented reality display region extends in a field of view between a first boundary line and second boundary line of the field of view; at least one augmented reality emitter which emits light to an eye of a user via the augmented reality display region, the light represents an augmented reality image having a boundary; and at least one control circuit, the at least one control circuit is configured to cause the opacity filter to provide a region having a shape which corresponds to a shape of the augmented reality image, to provide the region with an opacity which is relatively high when the augmented reality image is at least a specified distance from the first boundary line and the second boundary line, and to provide a gradual transition in the opacity to a relatively low opacity as a head of the user moves sideward and the augmented reality image moves correspondingly toward the first boundary line, the gradual transition is based on a distance between the first boundary line and the boundary of the augmented reality image.
