<P>PROBLEM TO BE SOLVED: To adjust a touch sensor in a user environment. <P>SOLUTION: An input device having a plurality of keys includes: a pad for detecting capacitance in association with each of a plurality of keys; and an illumination corresponding to each of the plurality of keys. The input device is configured to turn on the illumination corresponding to the key whose operation is valid, and to turn off the illumination corresponding to the key whose operation is invalid. In this case, the input device is configured to measure the output value of a pad corresponding to at least one or more invalid keys, and to calculate a correction value for correcting the output of the pad by using the output value, and to correct the output of at least one or more pads. <P>COPYRIGHT: (C)2012,JPO&INPIT |
