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.

Abstract: A fingerprint sensor apparatus including a sampling unit, an image analysing unit and a processor is provided. The sampling unit senses a fingerprint image. The image analysing unit analyses an image parameter of the fingerprint image to obtain an image data, and compares the image data to a reference data to obtain a comparison result. The comparison result includes that the image data corresponds to one of a plurality of stages. The stages are determined based on the image parameter, and the different stages correspond to different pressure regions. The processor controls an electronic device to execute a predetermined operation according to the stage corresponding to the image data. In addition, a method for controlling the fingerprint sensor apparatus is also provided.
