an array of light field shaping elements (LFSEs) to shape a light field emanating from said pixels and thereby at least partially govern a projection thereof from said pixels toward a given user pupil location; and a hardware processor operable on pixel data for an input image to output adjusted image pixel data to be rendered via said LFSEs to adjust user perception from said given user pupil location in accordance with a variable perception adjustment mapping that varies across the input image thereby rendering a perceptively adjusted version of the input image according to said variable perception adjustment mapping. ### Claim 2 (depends on 1) The device of claim 1, wherein said hardware processor outputs said adjusted pixel data as a function of adjusted image ray traces digitally computed for each given pixel of at least some of the array of pixels that intersect said user pupil location. ### Claim 3 (depends on 1) The device of claim 1, wherein said perceptive adjustment mapping is defined between respective designated boundary image perception planes. ### Claim 4 (depends on 3) The device of claim 3, wherein said perceptive adjustment mapping is defined by a greyscale mapping. ### Claim 5 (depends on 1) The device of claim 1, wherein said perceptive adjustment mapping results in defining distinct visual perception zones associated with respective visual perception parameters. ### Claim 6 (depends on 1) The device of claim 1, wherein said perceptive adjustment mapping results in a progressive perception adjustment of the input image. ### Claim 7 (depends on 1) The device of claim 1, wherein said perceptive adjustment mapping digitally simulates a multi-focal effect for distinct portions of the input image. ### Claim 8 (depends on 7) The device of claim 7, wherein said multi-focal effect comprises a progressive multi-focal effect. ### Claim 9 (depends on 1) The device of claim 1, further comprising a pupil tracker or pupil tracking interface operable to dynamically track and automatically accommodate for changes in said given user pupil location. ### Claim 10 (depends on 1) The device of claim 1, wherein said array of LFSEs comprises a lenslet array. ### Claim 11 (depends on 1) The device of claim 1, wherein said variable perception adjustment mapping defines respective perception adjustment zones to be perceptively rendered side-by-side. ### Claim 12 (depends on 11) The device of claim 11, wherein said respective perception adjustment zones are to be perceptively rendered side-by-side in a 2-dimensional grid. ### Claim 13 (depends on 11) The device of claim 11, wherein each of said perception adjustment zones corresponds to an optotype simultaneously rendered in each of said zones side-by-side to subjectively assess a user's reduced visual acuity. ### Claim 14 (depends on 11) The device of claim 11, wherein at least some of said perception adjustment zones are dynamically variable so to subjectively assess a user's reduced visual acuity. ### Claim 15 (depends on 11) The device of claim 11, wherein each of said perception adjustment zones are defined by a respective set of one or more visual acuity parameters.
