Abstract

The embodiments of the invention disclose an image processing method, an apparatus, and a mobile terminal. The method includes acquiring a module image corresponding to a contact surface of a fingerprint identification module; receiving a fingerprint image acquisition instruction; based on the fingerprint image acquisition instruction, acquiring a fingerprint image formed by the contact surface of the fingerprint identification module; conducting interference-removing processing on the fingerprint image based on the module image. The method conducts interference-removing processing on the fingerprint image through acquiring the module image, and eliminates the interference imposed on the fingerprint image due to tarnished contact surface of the fingerprint identification module, thus increasing the accuracy of fingerprint identification.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to an image processing method, device and mobile terminal. Background technique [0002] With the development of mobile terminals such as smart phones, fingerprint recognition technology has become the standard configuration of flagship models of mainstream mobile terminal manufacturers. Fingerprint recognition can not only realize functions such as unlocking and waking up the terminal, but also help improve the security of mobile payment. With the wide application of fingerprint identification technology, the requirements for the accuracy of fingerprint identification are also getting higher and higher. [0003] In mobile terminals, fingerprint recognition realizes the recognition of individual fingerprints through a specific fingerprint recognition sensing module. Fingerprints refer to the ridges produced by the uneven skin on the front of the fingertips. The ridges ar...
