The embodiment of the invention discloses a fingerprint image acquisition method. The fingerprint image acquisition method comprises the following steps of: detecting whether a fingerprint identification module is pressed or not; if so, sequentially acquiring multiple fingerprint images; determining the coverage rate of the multiple fingerprint images; judging whether the acquisition state of the fingerprint identification module is steady or not according to the coverage rate of the multiple fingerprint images; and if so, acquiring one fingerprint image as a target fingerprint image or taking the last acquired fingerprint image in the multiple fingerprint images as the target fingerprint image. The embodiment of the invention further provides a terminal. By means of the embodiment of the invention, the acquisition state stabilization time of the fingerprint identification module can be rapidly judged; the fingerprint image can be acquired in time; and thus, the fingerprint unlocking efficiency is increased easily.
