Claim Text:
1. A computer-implemented method comprising: projecting, using a projector, an image onto a surface; measuring one or more distances between the projector and one or more corresponding points of the surface; determining whether the surface is non-perpendicular in relation to an optical path of the projector, based on the one or more measured distances; determining, based at least in part on the one or more measured distances, a distortion of one or more pixels of the projected image caused by the surface being non-perpendicular in relation to the optical path of the projector; and in conjunction with projecting the image onto the surface, varying a length and a height of one or more individual pixels of the projected image substantially simultaneously based at least in part on the one or more measured distances to correct for the distortion.
