1. A computer-implemented method, comprising:
acquiring pixel coordinates of pixels of an image captured by a camera adjoining an electronic display device;
wherein the camera has an off-axis position from a principal axis extending from a predetermined location of an apparent camera on the electronic display device;
mapping, by a predetermined de-skewing transformer, the pixel coordinates to de-skewing coordinates aligned with the principal axis;
correcting for the off-axis position of the camera by generating a de-skewed image based on the de-skewing coordinates, wherein the de-skewed image is perpendicular to the principal axis; and
for one or more selected images of a plurality of sequential images, switching between a de-skewed rendering of the one or more selected images in response to a distance between the camera and an identified object appearing in the one or more selected images being greater than or equal to a predetermined distance and an unmodified rendering of the one or more selected images in response to the distance being less than the predetermined distance.
