Abstract
An electronic apparatus and an operating method thereof are provided. The electronic apparatus includes an optical fingerprint sensor and a processor. The optical fingerprint sensor is configured to obtain a fingerprint image. The processor is coupled to the optical fingerprint sensor and analyzes the fingerprint image to calculate at least one of a color pixel ratio and a light reflectance corresponding to the fingerprint image. The processor searches a background database according to at least one of the color pixel ratio and the light reflectance to obtain a background image. The processor corrects the fingerprint image according to the background image to obtain a corrected fingerprint image.
