This varied touch detection signal is transmitted to each touch detection wire (SVn). The transparency detection unit 210 converts the contact detection signals detected by each contact detection wire (SVn) into digital signals according to the amount of current or voltage, and patterns them to a preset frame size to generate a fingerprint image and fingerprint image data. do.
