A mobile terminal and controlling method thereof are disclosed. The present invention includes a display unit configured to display an image including at least one object on a screen and a controller searching for at least one associated information on the object using a partial image corresponding to the object in the image, the controller displaying the searched associated information. Accordingly, when a user searches for an information on a specific object in an image using an image search function, it is unnecessary for the user to crop a partial image corresponding to the specific object in the image one by one. Instead, a mobile terminal automatically recognizes the specific object in the image and is then able to search for at least one associated information on the specific object using a partial image of the automatically recognized specific object.
