1. A method for controlling individual pixels of an electronic display screen displaying an input image, the method comprising:
receiving, by at least one processor, an output image from a camera capturing the display screen;
estimating, by the at least one processor, a difference in perceptual aspect between each of one or more pixels of the output image and each of one or more correlated pixels of the input image based on a geometric relation between the camera and the one or more correlated pixels of the input image, the geometric relation including an angular offset between the camera and the one or more correlated pixels; and
in response to the difference being greater than a threshold, adjusting, by the at least one processor, at least one parameter for controlling display of the input image on the electronic display screen by an amount calculated, for each of the one or more correlated pixels of the input image, to reduce the difference.
