Abstract: A terminal includes an image input unit, an image output unit, and a controller to transmit image frames generated by the image input unit to the image output unit in real time if a preview mode is activated. If an object is selected within an image displayed on the screen of the image output unit, the controller identifies the selected object, detects an image frame, in which an object matched to the identified object is present, processes the detected image frame, and transmits the processed image frame to the image output unit so that an image can be edited before the photographed image is recorded.
