<P>PROBLEM TO BE SOLVED: To suppress decline in a surface shape recognition rate even when arranging an impedance detection unit in a capacity detection region and performing a living body determination. <P>SOLUTION: A data compensation part 50 creates supplement data supplementing the uneven data 27A in the line range of an arrangement region among selection rows, and outputs the data to a line selector 28 as uneven data 50S, based on the uneven data at the arrangement position of a capacity detection unit 20 adjacent to the arrangement region of an impedance detection unit 30 among the uneven data 27A from an A/D conversion part 27. <P>COPYRIGHT: (C)2010,JPO&INPIT |
