1. An electronic device comprising: a finger biometric sensor comprising an array of electric field sensing pixels and image data output circuitry coupled thereto and capable of outputting image data from a plurality of sub-arrays of the array of electric field sensing pixels; a dielectric layer over the array of electric field sensing pixels and causing electric field diffusion so that the image data output circuitry generates image data corresponding to a blurred finger image, the electric field diffusion having a diffusion function associated therewith; and deblurring circuitry coupled to the image data output circuitry and capable of processing the image data from each of the plurality of sub-arrays of the array of electric field sensing pixels in accordance with respective deblurring functions for each of the plurality of sub-arrays based upon the diffusion function to produce processed image data representative of a deblurred finger image.
