1. A method comprising: extracting, by a processor, a setting from a file associated with a wide-angle camera; determining, by the processor, based on the setting, a first set of coordinates of a pixel of a first image, wherein the determining of the first set of coordinates is for each cell of a sparse conversion map represented as a first look-up table, wherein the sparse conversion map corresponds to a sparse grid of pixels of a second image, wherein the first image is captured via the wide-angle camera; determining, by the processor, via interpolating the first set of coordinates, a second set of coordinates of a pixel of the first image such that the first image would be less rectilinear than the second image when displayed, wherein the determining of the second set of coordinates is for each cell of a full conversion map, wherein the second set of coordinates is represented as a second look-up table, wherein the full conversion map corresponds to a full grid of pixels of the second image; and instructing, by the processor, based on the interpolating, a display to present the second image, wherein the first image is less rectilinear than the second image.
