Abstract

An electronic device may include an array of finger sensing pixels and data acquisition circuitry coupled to the array. The data acquisition circuitry may be capable of acquiring finger biometric data from each sub-array of the array, and acquiring spoof detection data from at least one of the sub-arrays in an interleaved fashion with the finger biometric data.

First claim

That which is claimed is:

1. An electronic device comprising:
an array of finger sensing pixels operating based upon electric field sensing;
finger drive circuitry coupled to said array of finger sensing pixels; and
data acquisition circuitry coupled to said array of finger sensing pixels and configured to
acquire finger biometric data from each of a plurality of sub-arrays of said array of finger sensing pixels, and
acquire spoof detection data from at least one of the plu…
