Abstract
Near-eye display systems in accordance with embodiments of the invention enable accommodation-invariant display control. One embodiment includes a near-eye display; a processor; a memory containing a target image and an accommodation-invariant display application; where the processor is configured by the accommodation-invariant display application to calculate an impulse response of the near-eye display; calculate a compensation image by generating a deconvolved color channel of the target image using a ratio of the target image and the impulse response, where the compensation image is a representation of the target image that remains in focus at a plurality of distances from the near-eye display; and display the compensation image on the near-eye display.
