Abstract
An autostereoscopic display includes a light-emitting panel and a lenticular array in which a focal length of a lenticular lens is different from its thickness. For an intersection of a given row of light-emitting cells and a given lenticular lens, a given viewing direction from a given eye toward said intersection is determined. From light-emitting cells arranged on the given row and on whose optical path the given lenticular lens lies, a set of light-emitting cells whose light travels toward the given eye is determined. Corresponding regions on a curved surface of the given lenticular lens through which light from individual light-emitting cells of the set pass toward the given eye are identified and mapped to respective pixel locations in an image to be presented. Pixel values of pixels located at these pixel locations in the image are retrieved and used to generate an output image for display.
