Communication device and communication method thereof

摘要

A communication device provides a face detection module and a face recognition module. The face detection module detects faces in a photo input by a user. The face recognition module searches the detected faces in a storage system of the communication device. If the detected faces do not exist in the storage system, the communication device prompts the user to edit communication information of the detected faces. If the user wants to dial a phone number, the communication device searches the storage system for the phone number of a selected face in a photo and dials the phone number. If a phone number is calling in, the communication device displays a photo corresponding to the phone number, and highlights a face corresponding to the phone number.
