Abstract:
Some implementations provide a multi-focus display system that renders images at multiple focus distances for display in conjunction with the use of appropriately powered lenses. For example, an HMD may include a fast switching lens element that allows quickly alternating between two or more focus distances. The displayed images are configured to correspond to the alternating focus distances by adjusting a high-frequency part of the images. This can provide a more natural user experience that will include near objects that require the user's eye to focus on a close focal depth plane and far objects that require the user's eye to focus on a far focal depth plane. Moreover, the user experience can be provided with little or no loss of brightness and without requiring processor and resource intensive computations.
