Input device, electronic apparatus, and method for driving input device

摘要

To provide an input device, an electronic device, and a method for driving an input device where an increase in the amount of processed information is restricted to make processing systems simple, an input device includes a plurality of capacitive sensing circuits arranged in a matrix and an amp circuit to output detected information from the capacitive sensing circuits. An output processing section performs a plurality of field scans to read fingerprint information from the capacitive sensing circuits and thereby identify particular capacitive sensing circuits to acquire detected information necessary for processing.
