ABSTRACT:
A head-mounted display includes an aperture mask between the eye and a viewfinder to mask the line artifacts resulting from visible edges of mechanisms, such as imagers, within the display. The aperture has a translucent area that matches the geometry of the edge desired to be masked. In an application where a high-resolution image is presented to one eye, centered within a lower-resolution image presented to the other eye, the aperture is positioned to mask the edges of the high-resolution image source. In an application where see-through is desired, the opaque area is sacrificed in favor of a partially transparent mask. The translucent area can be graduated so that a smooth transition area between the edges of the high-resolution display and the lower-resolution display is achieved.
