Document Type and Number:
WIPO Patent Application WO/2018/120912
Kind Code:
A1
Abstract:
Provided are a fingerprint collection method and device, and a terminal. The method comprises: upon entering a fingerprint navigation state in response to detection of a touch operation, a fingerprint collection device outputting a first fingerprint collection signal, the first fingerprint collection signal being used for periodically and cyclically collecting and ceasing collecting fingerprint data by the fingerprint collection device; and upon entering a non-fingerprint navigation state in response to detection of a touch operation, the fingerprint collection device outputting a second fingerprint collection signal, the second fingerprint collection signal being used for continuously collecting fingerprint data by the fingerprint collection device. In the method, the fingerprint collection device is controlled to discontinuously perform an operation in the fingerprint navigation state, thereby reducing interference of the fingerprint collection device with a radio-frequency signal.
