Abstract
Embodiments of the present disclosure relate to a method and an apparatus for acquiring a fingerprint image and a terminal device. The method includes determining target light information of a light environment of a to-be-identified fingerprint; determining a target operating parameter corresponding to the target light information according to a correspondence between light information and operating parameters; and acquiring a first fingerprint image of the to-be-identified fingerprint according to the target operating parameter. According to the method and the apparatus for acquiring the fingerprint image and the terminal device of the embodiments of the present disclosure, the operating parameter used for a time when the fingerprint image of the to-be-identified fingerprint is acquired can be dynamically adjusted according to different light environments, so that an intended result of using an optical fingerprint in different environments is achieved without increasing hardware cost.
