Abstract
A finger sensing device may include an array of finger sensing pixels to receive a user's finger adjacent thereto. Each finger sensing pixel may include a finger sensing electrode. The finger sensing device may include a finger drive electrode configured to couple a drive signal through the user's finger to the array of finger sensing pixels. The finger sensing device may also include differential pixel measurement circuitry coupled to the array of finger sensing pixels and configured to generate a plurality of interpixel difference measurements for adjacent pairs of the finger sensing pixels.
