Abstract

The embodiment of the invention discloses a fingerprint acquisition method and a related device, an under-screen fingerprint module is arranged in a preset area of a display screen of electronic equipment, and the method comprises the following steps: starting a light sensor to acquire a light sensing value; detecting whether the light sensing value is greater than or equal to a preset threshold;if yes, at least one first fingerprint image is collected when the brightness of the display screen is first brightness, at least one second fingerprint image is collected when the brightness of the display screen is second brightness, at least two fingerprint images are obtained, and the first brightness is smaller than the second brightness; and determining a target fingerprint image according to the at least two fingerprint images. According to the embodiment of the invention, the problem of light interference can be solved, the accurate fingerprint is collected, the unlocking success rateis improved, and the accuracy and intelligence of fingerprint collection of the electronic equipment are improved.

Description

technical field [0001] The present application relates to the technical field of intelligent mobile terminals, in particular to a fingerprint collection method and related devices. Background technique [0002] At present, smart electronic devices on the market basically support touch screen operation functions. Users usually enter several sets of fingerprints into the terminal database in advance, and users can directly click the screen to operate and interact with the device. Some smart terminals also have a fingerprint recognition function, which can be used for wake-up unlocking, identity verification, etc. However, external light can interfere with the fingerprint recognition function, resulting in the inability to quickly perform operations such as unlocking, which reduces the user experience. Contents of the invention [0003] Embodiments of the present application provide a fingerprint collection method and a related device, which improve the accuracy and intellig...
