Abstract
A system, method, and computer program product are provided for producing images for a near-eye light field display. Defect information for a first pixel of a microdisplay of a near-eye light field display device is received and a second pixel of the microdisplay is identified, where the first pixel and the second pixel contribute to a portion of the retinal image. Based on the defect information, a value of the second pixel within an array of elemental images is modified to produce a corrected array of elemental images for display by the microdisplay. An optical apparatus of the near-eye light field display device may, for example, be a microlens of a microlens array positioned between a viewer and an emissive microdisplay or a pinlight of a pinlight array positioned behind a transmissive microdisplay relative to the viewer.
