1. A system comprising:
an electronic display configured to display image data and obtain touch scan data corresponding to at least one touch sense region of the electronic display;
an image processing system configured to:
receive an image frame data packet comprising the image data; and
determine statistical data corresponding to the at least one touch sense region of the electronic display based on the image data; and
a touch processing system configured to:
determine an estimated charge error expected to effect the touch scan data during a touch sensing operation based on the statistical data and a model of a multi-phase sensing operation;
compensate the touch scan data based on the estimated charge error to obtain compensated touch scan data; and
use the compensated touch scan data to determine a proximity of a capacitive object to the at least one touch sense region of the electronic display.
