Abstract: A fingerprint sensor apparatus including a fingerprint sensor and a processor circuit is provided. The fingerprint sensor is configured to capture a plurality of local fingerprint images of a fingerprint. The plurality of local fingerprint images include at least one first local fingerprint image and at least one second local fingerprint image. The processor circuit is electrically connected to the fingerprint sensor. The processor circuit is configured to identify the fingerprint according to the at least one first local fingerprint image of the local fingerprint images. The local fingerprint images form a global fingerprint image of the fingerprint. In addition, a method for sensing a fingerprint is also provided.
