Abstract
The invention relates to a method for compensating a misalignment between an optical grating (3) and a subpixel array (2) of an autostereoscopic display (1), the subpixel array (2) comprising at least two subsets of subpixels (5), each of the subsets corresponding to one of at least two viewing zones (10, 10') and forming a family of parallel stripes at least roughly aligned with a structure of the optical grating (3), stripes of the different subsets alternating in a cyclical sequence and each of the stripes comprising a plurality of pixels, each of these pixels being formed by a group of subpixels (5). In the course of this method, a misalignment direction matrix assigning a misalignment direction value to each of the pixels as well as a misalignment magnitude matrix assigning a misalignment magnitude value to each of the pixels are determined. Finally, a weight function is determined for each of the pixels, the weight function assigned to each of the pixels being dependent on the misalignment direction value and the misalignment magnitude value assigned to the respective pixel. The invention relates, furthermore, to a corresponding autostereoscopic display (1).
