1. A method comprising: acquiring a touch image from a touch sensor panel; reconstructing the acquired touch image from the touch sensor panel, wherein reconstructing the touch image includes adjusting one or more touch values of the acquired touch image for a negative pixel effect; and compensating the acquired touch image for the negative pixel effect by computing a composite image, wherein the composite image is computed by weighting the acquired image, weighting the reconstructed touch image, and combining the weighted acquired image and weighted reconstructed image, wherein the weighting of the acquired image and the reconstructed image is based on a magnitude of the negative pixel effect.
