Patent ID: 8648897

Claim:
A system for viewing image data comprising: a head borne image source for imaging an object and providing the image data wherein the head borne image source is configured to image the object along a first axis; an eyepiece lens assembly configured to provide an image along a second axis, wherein the second axis is parallel to and displaced from the first axis by a distance D; and a display device for receiving the image data and displaying the image data to a user's eye via the eyepiece lens assembly, a controller for determining, from the distance D and from a focus position of the head borne image source: a focus adjustment of the eyepiece lens assembly, a target distance between the eyepiece lens assembly and the display, a displacement of the image data displayed on the display device to compensate for a parallax resulting from the displacement of the second axis from the first axis and divergence of lines of sight to objects at different distances; and an adjustment of the displacement of the image data displayed on the display device based on the distance D and the determined focus adjustment.
