<p>A device and a method for adjusting a sensitivity of a touch key in various kinds of digital devices are provided to improve an incorrect operation of the touch key owing to noises generated in the digital device by setting a reference input value to a value adding a predetermined level to a low data value and storing the reference input value to a memory. A detector detects a low data value by scanning a plurality of touch keys when an event occurs(S10). A storage unit stores a reference input touch sensitivity value and a function of each touch key. A controller compares the detected low data value of each touch key with the reference input touch sensitivity value stored in the storage unit(S12). The controller updates and stores the reference input value of each touch key to the storage unit by adding a predetermined level to the reference input value when the detected low data value of each touch key is lower than the reference input touch sensitivity value stored in the storage unit(S13-S15).</p> |
