The portable terminal includes: a controller which receives signals corresponding to a user key pressed from the plurality of input buttons and outputs image data to be displayed on each of the plurality of input buttons using the received signals; and a plurality of buttons for inputting a key from a user and outputting a signal corresponding to the key pressed, and for receiving the image data from the controller and displaying the received image data. Accordingly, by using the display buttons for displaying variable images corresponding to specific functions as well as an essential function of inputting keys from a user when a specific function is input in the portable terminal such as a cell phone, a plurality of functions can be input with only a limited number of buttons, providing speed and convenience to the user for function input. ## Claims ### Claim 1 A portable terminal comprising: an image capturing unit configured to capture an image; a transceiver configured to communicate with an external device using a wireless network; a main display for displaying the captured image; a plurality of displayable inputs respectively configured to display a function related to image photographing or video photographing in response to a signal to capture an image; a memory configured to store the captured image; a controller configured to: control at least one of the plurality of displayable inputs to display a storage function for storing the captured image after the image capturing unit captures the image; and control at least one of the plurality of displayable inputs to display a categorizing function for storing the captured image according to at least one category. ### Claim 2 (depends on 1) The portable terminal of claim 1, wherein the plurality of displayable inputs are displayed adjacent to the main display in a landscape mode. ### Claim 3 (depends on 1) The portable terminal of claim 1, wherein the plurality of inputs comprises a display part for receiving image data from the controller and displaying the received data, and a transparent cover for covering the display part. ### Claim 4 (depends on 1) The portable terminal of claim 1, wherein the at least one category can be changed in response to a user input made on at least one of the plurality of displayable inputs. ### Claim 5 A method of storing an image to a portable terminal comprising: capturing the image; displaying the captured image in a main display of the portable terminal; displaying, on a plurality of displayable inputs, a function related to image photographing or video photographing in response to a signal to capture an image; displaying, on at least one of the plurality of displayable inputs, a storage function for storing the captured image; displaying, on at least one of the plurality of displayable inputs, a categorizing function for storing the captured image according to at least one category; and storing the captured image according to at least one category in response to a user input made on at least one of the plurality of displayable inputs displaying the categorizing function, wherein the portable terminal is configured to communicate with an external device using a wireless network. ### Claim 6 (depends on 5) The method of claim 5, wherein the plurality of displayable inputs are displayed adjacent to the main display in a landscape mode. ### Claim 7 (depends on 5) The method of claim 5, wherein the plurality of inputs comprises a display part for receiving image data from the controller and displaying the received data, and a transparent cover for covering the display part. ### Claim 8 (depends on 5) The method of claim 5, wherein the at least one category can be changed in response to a user input made on at least one of the plurality of displayable inputs.
