A mobile terminal, comprising: a touchscreen; a camera; and a controller configured to: display a graphic object on the touchscreen that is linked with an image capture function for capturing an image through the camera, execute the image capture function in response to a first touch input applied to the graphic object, and execute both the image capture function and a linked function corresponding to the image capture function in response to a second touch input, which is different from the first touch input, applied to the graphic object, wherein the linked function is a memo function, characterized in that the controller is further configured to: display a preview image obtained by the camera within an execution screen of the linked function when both the image capture function and the linked function are executed; sequentially capture a plurality of images in response to a sequential touch input on the preview image; generate link information indicating that the plurality of images are linked with each other; execute a function of editing the linked plurality of images based on a third touch input applied to the preview image, wherein the third touch is different from the first and the second touch input; edit the plurality of images based on a pre-set type of touch applied to the plurality of images; change the link information based on the edited plurality of images; display the edited plurality of images on the execution screen of the linked function; and store memo information containing the edited plurality of images. a touchscreen; a camera; and a controller configured to: display a graphic object on the touchscreen that is linked with an image capture function for capturing an image through the camera, execute the image capture function in response to a first touch input applied to the graphic object, and execute both the image capture function and a linked function corresponding to the image capture function in response to a second touch input, which is different from the first touch input, applied to the graphic object, wherein the linked function is a memo function, characterized in that the controller is further configured to: display a preview image obtained by the camera within an execution screen of the linked function when both the image capture function and the linked function are executed;
