Abstract

The invention provides a fingerprint identification device and a fingerprint identification method. The fingerprint identification device comprises a first detection module and a second detection module, wherein the first detection module is used for detecting an attribute of a touch object; the second detection module is used for identifying line information of the touch object; the first detection module is used for obtaining color information of the touch object pressed on the fingerprint identification device; the color information comprises a first pigment coordinate; when the first pigment coordinate is not in a first threshold range, the attribute of the touch object is a living body and an indicator signal is output to the second detection module; and the second detection module starts and senses a fingerprint image of the touch object according to the indicator signal. The fingerprint identification device is relatively low in energy consumption.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a fingerprint identification device and a fingerprint identification method. Background technique [0002] With the development of information technology and electronic technology, electronic devices (such as mobile phones, tablets, etc.) , instant messaging, online payment, etc. People are increasingly dependent on terminals, and various types of private information are stored on electronic devices, which makes the security of electronic devices particularly important. In the prior art, a fingerprint identification device is installed in an electronic device. Since a fingerprint is a texture formed by uneven skin on the surface of a finger, and the fingerprint feature is unique and stable, the fingerprint sensor can be used to identify the user's identity to ensure that the terminal security. However, the fingerprint identification device of the existing electronic equipme...
