Abstract
A method for optical fingerprint collection and related products are provided. The method includes the following. When a terminal receives a fingerprint collection instruction, the terminal detects, with an optical sensor, a current ambient light intensity and sends, with the optical sensor, the current ambient light intensity to an application processor (AP). According to a correspondence relationship between ambient light intensities and light source intensities, the terminal obtains, with the AP, a target light source intensity corresponding to the current ambient light intensity. The terminal controls, with an optical fingerprint recognition module, an internal light source to emit lights having the target light source intensity and performs, with the optical fingerprint recognition module, fingerprint collection with the lights having the target light source intensity.
