Claim 15:
16. A fingerprint sensing device, comprising:
a sensing pixel array, comprising a first sensing pixel area and a second sensing pixel area surrounding the first sensing pixel area; and
a plurality of color filter units, disposed above the sensing pixel array,
wherein the first sensing pixel area is configured to obtain a plurality of first sensing signals and the fingerprint sensing device is configured to generate a first fingerprint image according to the first sensing signals,
wherein the first fingerprint image is adapted to be used for examining whether a finger which triggers a fingerprint sensing request is real or fake,
wherein the color filter units comprise red color filter units, blue color filter units and background-color filter units, and wherein number of the background-color filter units is greater than number of the red color filter units and number of the blue color filter units.
