Problems solved by technology

However, in the related art, the fingerprint sensing device cannot clearly display the information or the position of the fingerprint image that has been extracted or the fingerprint image that was not successfully extracted during the registration process.
In such a situation, the user cannot clearly know how to move the finger so that the fingerprint sensing device can extract the fingerprint image that was not extracted during the touch operation.

Abstract

The invention discloses a fingerprint sensing device and a method for sensing the fingerprint. 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.

Description

technical field [0001] The invention relates to a sensing device and a method for sensing objects, and in particular to a fingerprint sensing device and a method for sensing fingerprints. Background technique [0002] In general technology, when the user wants to use the fingerprint sensing device to identify the user's finger, the user can use the fingerprint sensing device to perform a registration process to register the fingerprint of the finger, so that the fingerprint image of the finger is stored in the fingerprint sensing device. device. After finishing the registration process, the fingerprint sensing device can use the stored fingerprint image to identify the user's fingerprint. [0003] Because the size of the fingerprint sensor of the fingerprint sensing device may be smaller than a complete fingerprint, the user may need to perform multiple touch operations with fingers so that the fingerprint sensing device acquires enough fingerprint images to identify the us...
