Problems solved by technology

[0003] The fingerprint image collection method of the existing fingerprint sensing device includes two collection methods of pressing and sliding. However, the sliding collection method will cause image deformation and affect the recognition effect, while the image collected by the pressing collection method is limited. The area of ​​the fingerprint sensing element array of the fingerprint sensing device, and the lack of correlation between the images collected by successive presses, makes it difficult for the sampled images to meet the recognition requirements

Abstract

The invention discloses a fingerprint sensing device, a product with a fingerprint sensing function and a fingerprint sensing method of the product. The fingerprint sensing device comprises a fingerprint acquisition unit and an image reconstruction unit. The fingerprint acquisition unit is used for acquiring a fingerprint image of a finger, pressing the fingerprint acquisition unit, of a user. The image reconstruction unit is used for instructing the finger to conduct corresponding movement operation on the fingerprint acquisition unit according to the fingerprint image acquired by the fingerprint acquisition unit so as to acquire different secondary fingerprint images; the image reconstruction unit conducts correlation analysis on the secondary fingerprint images acquired by the fingerprint acquisition unit, conducts splicing on the secondary fingerprint images according to the analysis result, and judges whether a fingerprint image formed through splicing meets predetermined requirements or not, and if not, the image reconstruction unit continues instructing the finger to conduct corresponding movement operation on the fingerprint acquisition unit according to the fingerprint image formed through splicing until the situation that the fingerprint image formed through splicing meets the predetermined requirements is determined.

Description

technical field [0001] The invention relates to the technical field of fingerprint sensing, in particular to a fingerprint sensing device, an electronic product with a fingerprint sensing function, and a fingerprint sensing method for the electronic product. Background technique [0002] In order to improve the safety of electronic products, more and more electronic products are equipped with fingerprint sensing devices at present, and functions such as unlocking and payment are performed by collecting fingerprint images of users. [0003] The fingerprint image collection method of the existing fingerprint sensing device includes two collection methods of pressing and sliding. However, the sliding collection method will cause image deformation and affect the recognition effect, while the image collected by the pressing collection method is limited. The area of ​​the fingerprint sensing element array of the fingerprint sensing device and the lack of correlation between the im...
