Abstract
In one embodiment, a computing system may determine, for a current frame to be displayed and using an eye tracking system, a current eye position of a viewer. The system may determine a first array of scaling factors based on the determined current eye position of the viewer. The system may retrieve one or more second arrays of scaling factors used for correcting one or more proceeding frames of the current frame. The system may determine a third array of scaling factors based on the first array of scaling factors determined based on the current eye position and the one or more second arrays of scaling factors used for correcting the proceeding frames. The system may adjust pixel values of the current frame based at least on the third array of scaling factors. The system may output the current frame with the adjusted pixel values to a display.
