  • Patent number: 10712563
    Abstract: Near-to-eye displays allow a user to be presented with images that are either augmented to address defects or aberrations within their vision or provide additional information. However, an acquired image typically contains content at different depths and absent depth information image processing applied to the acquired image may discount or apply an image modification that reduces visibility of an object. Accordingly, it would be beneficial for such near-to-eye displays to exploit depth information within the image processing and/or generate depth maps allowing images presented to the user to account for depth. It would be further beneficial for such enhancements to be compatible with the evolving low weight, low volume, low complexity, and low cost near-to-eye display systems. It would be further beneficial to provide a user with other non-visual stimuli based upon depth information within the image.
