Content normalization on digital displays

摘要

Described herein are various technologies pertaining to dynamically modifying content that is desirably displayed on a large display to correct for distortions caused by a position of eyes of a user relative to the large display. Modification of the content is undertaken dynamically based at least in part upon a sensed or computed position of the user relative to the display.

1. A method, comprising:
receiving positional information that indicates a position of a user in three dimensions relative to a display; receiving image data, the image data defining an image that is to be displayed on the display, the image data comprising a plurality of pixels with a corresponding plurality of values assigned thereto; and by a processor, dynamically altering values of a subset of the plurality of pixels based at least in part upon the positional information to generate a modified image, wherein altering the values of the subset of the plurality of pixels comprises:
shrinking a first region of the image in the image data; andstretching a second region of the image in the image data, the second region surrounds the first region, wherein the modified image corrects distortions existent in the image caused by the position of the user relative to the subset of the plurality of pixels such that imagery in the modified image displayed at a periphery of the display appears to the user as being orthogonal to a line of sight between the user and the imagery.
