1. A method for operating a camera included in a touch input device including a touch screen which includes touch position sensing electrode and touch pressure sensing electrode, the method comprising:

  • determining, by a processor, whether the camera is underwater or not;

    detecting, by the processor, a touch position of an object on the touch screen based on a capacitance change amount using the touch position sensing electrode if the camera is not underwater;

    detecting, by the processor, the touch position of the object on the touch screen based on a capacitance change amount due to the touch pressure using the touch pressure sensing electrode if the camera is underwater, the touch position being detected by;

    determining a capacitance pattern for a varying capacitance throughout the touch screen when the touch screen is underwater and no touch input occurs;

    resetting, by the processor, a varying reference capacitance for determining whether a touch input by the object occurs or not, the varying reference capacitance being reset based on the determined capacitance pattern when the touch screen is underwater and no touch input occurs; and

    receiving, by the touch screen, the touch pressure by the object underwater; and

    detecting, by the processor, the touch position on the touch screen based on the capacitance change amount due to the touch pressure and the reset varying reference capacitance; and

    controlling operation of the camera according to the detected touch position by the object.
