1. A method comprising:

  • computing at least one parameter indicative of a grounding condition of a user of a touch sensor panel;

    comparing the computed parameter to a threshold to determine whether a negative pixel effect applies to the touch sensor panel; and

    based on the comparison, compensating a touch image of the touch sensor panel for the negative pixel effect by replacing the touch image with a reconstructed touch image having the negative pixel effect substantially reduced.
