<P>PROBLEM TO BE SOLVED: To provide a touch panel system which can surely remove various kinds of noise. <P>SOLUTION: A touch panel system 1 includes a main sensor 31 for detecting touch operation, a secondary sensor 32 for detecting noise components without detecting touch operation, and a subtraction part 41 for subtracting output signals of the secondary sensor 32 from output signals of the main sensor 31. The subtraction part 41 removes noise components from output signals of the main sensor 31 by subtraction processing to extract an original signals of touch operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
