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;
write the statistical data to memory;
write a doorbell indication to the memory after each respective row of the image data is sent to the electronic display; and
a touch processing system configured to:
read the statistical data from the memory;
compensate the touch scan data using the statistical data 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.
