ABSTRACT:
A sweep-type fingerprint sensor module includes a microprocessor and a sweep-type fingerprint sensor, which includes a substrate, and a sensing members array, a speed-detecting unit, and a processing circuit on the substrate. The array is composed of plural fingerprint sensing members. When the finger sweeps across the fingerprint sensor, the array sequentially acquires plural fingerprint fragment images from the finger with a sampling time interval. The speed-detecting unit is composed of first and second plate electrodes. The processing circuit processes and then outputs signals from the array and the speed-detecting unit. The microprocessor electrically connected to the processing circuit derives a sweeping speed of the finger by the time difference when the finger sweeps across the sensor surface and sequentially contacts the first and second plate electrodes, determines the sampling time interval and minimize the number of captured fragment images for re-construction of the initial complete fingerprint image.
