Abstract: A sensor device includes a fingerprint sensing module, configured to sense a first raw image using a first exposure time; and an exposure time adjusting module. The exposure time adjusting module is configured to obtain a first image according to the first raw image; determine whether the first image comprises a flicker noise; and adjust the first exposure time when the first image comprises the flicker noise, so as to mitigate the flicker noise.
