• a display, configured to display a user interface, wherein the user interface is configured to present content of the camera-related application, the non camera-related application or web media content, wherein the camera-related application is an application installed in the display device and configured to invoke the at least one camera to capture image during running of the application;
• a controller in communication with the display and the at least one camera, configured to:
• receive a command for obtaining recommendation information associated with content currently displayed in the user interface;
• determine whether an application corresponding to the content currently displayed in the user interface is the camera-related application, and in response to the application corresponding to the content currently displayed in the user interface being the camera-related application, display a first user interface, wherein the first user interface displays a first image captured by the at least one camera;
• in response to the application corresponding to the content currently displayed in the user interface being the non camera-related application, display a second user interface different from the first user interface, wherein the second user interface displays a screenshot image of the content currently displayed in the user interface,
• wherein the controller is further configured to:
• invoke a face recognition module to perform a face recognition on the first image, and send feature information of at least a first face recognized in the first image to a server;
• receive recommendation information associated with the first sent from the server;
• present the recommendation information associated with the first face in an information display area;
• wherein the information display area comprises a face thumbnail display sub-area and a content recommendation information display sub-area;
• the face thumbnail display sub-area displays one or more thumbnails of recognized faces in the first image in an image display area, wherein the one or more thumbnails comprise at least a thumbnail of the first face, and the thumbnail of the first face is located in a focus frame, and the content recommendation information display sub-area displays content recommendation information associated with the first face located in the focus frame;
• wherein a second face is further recognized in the first image in the image display area, the first face in the first image is marked, and the one or more thumbnails further comprise a thumbnail of the second face;
• in response to a focus frame switch command for switching from a first thumbnail of the first face to a second thumbnail of the second face, update the information display area to display content recommendation information associated with the second face;
• and,
• when the second face is in an overlapping area of the information display area and the image display area, move the second face to a center of the display.
