Patent attributes
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.
