Abstract
The present disclosure provides technical solutions for improving facial image capturing, recognition, and authentication, including: collecting a face image in response to a facial scan instruction (e.g., for facial recognition) using a camera of a mobile terminal; calculating a measure of image brightness (e.g., a luminance value) of the collected face image; enhancing, when a value of the measure of image brightness of the collected face image is less than a first preset threshold, luminance of light that is emitted from a display of the mobile terminal to a target luminance value, and re-collecting a face image using the camera of the mobile terminal and calculating a corresponding value of the measure of image brightness for the re-collected face image; and performing, when the value of the measure of image brightness of the re-collected face image falls within a preset value range, facial recognition based on the re-collected face image.
