1. A computing device comprises:
an image sensing grid operable to sense an item;
a plurality of drive sense circuits operable to:
provide drive signals to the image sensing grid;
detect an effect on one or more drive signals caused by the item being proximal to the image sensing grid; and
generate drive sense data based on the detected effect of the one or more drive signals; and
a processing module operable to:
generate a frame of image data regarding the item based on the drive sense data in accordance with a data reduction method, wherein the frame of image data corresponds to a plurality of measures of effect the item had on at least some of the drive signals provided to the image sensing grid during a frame interval; and provide reduced three-dimensional image data to a data circuit, wherein the reduced three-dimensional image data corresponds to changes in the frame of image data from frame to frame, and wherein the data circuit produces processed image data.
