The disclosure provides a fingerprint sensor and a fingerprint sensing method thereof. The fingerprint sensor includes an optical sensing array, an analog front end circuit and an image processing circuit. The optical sensing array is configured for sequentially outputting a plurality of analog fingerprint images corresponding to a finger. The analog front end circuit is coupled to the optical sensing array. The analog front end circuit is configured for sequentially receiving and converting the plurality of analog fingerprint images into a plurality of first digital fingerprint images. The image processing circuit is coupled to the analog front end circuit. The image processing circuit is configured for sequentially superimposing the plurality of first digital fingerprint images to generate an enhanced fingerprint image.
