Abstract
An input device includes an input-sensing unit that contains a capacitive input sensor and a sensitivity-sensing unit that contains a capacitive sensitivity sensor. The input-sensing unit senses position information obtained by touch operation of an operation body to the capacitive input sensor. The sensitivity-sensing unit senses sensitivity information obtained by touch operation of the operation body to the capacitive sensitivity sensor. The input device includes a control unit determining whether or not the output level of the position information from the input-sensing unit is adjusted based on the sensitivity information sensed by the sensitivity-sensing unit and a sensitivity-adjusting unit that adjusts an output level of the position information from the input-sensing unit based on a result of the determination of the control unit. The control unit controls the sensitivity-adjusting unit to adjust the output level of the position information received from the input-sensing unit.
