Abstract

The application discloses a fingerprint acquisition method and a fingerprint acquisition device. By the method, the fingerprint acquisition can be performed by controlling the acquisition window according to the first power. When an object to be acquired which contacts an acquisition window is detected, whether the object to be acquired is a fingerprint object or not is judged. If yes, fingerprint collection is carried out on the fingerprint object at second power, the first object is obtained according to the fingerprint object, and the second power is larger than the first power. Therefore, the scheme can increase the power and carry out fingerprint acquisition with the second power when the fingerprint object is determined to be the acquired object. The power consumption of the terminal equipment can be reduced, and the cruising ability of the terminal equipment is improved.
