1. An electronic device that senses a touch input to a screen, the electronic device comprising:
a touch sensor configured to sense the touch input to the screen; a storage configured to store different firmware corresponding to a plurality of input modes supported by the touch sensor; and a controller configured to, in response to an input mode being selected from among the plurality of input modes by a user, sense the touch input according to the selected input mode among the plurality of input modes, through execution of one of the different firmware corresponding to the selected input mode, wherein the plurality of input modes comprise a drawing mode and a touch mode, wherein the controller operates to sense the touch input through execution of a first firmware that is unable to recognize a multi-touch if the selected input mode is the drawing mode, and operates to sense the touch input through execution of a second firmware that can recognize the multi-touch if the selected input mode is the touch mode, and wherein the first firmware has a first touch sensing speed and the second firmware has a second touch sensing speed that is different from the first touch sensing speed.
