INFRARED SENSOR AND METHOD FOR DRIVING SAME

摘要

An infrared sensor is provided with a plurality of reference pixel units (2) arranged in matrix, and series capacitive elements (14) arranged to correspond to each of the reference pixel units (2). The reference pixel unit (2) is provided with an output line (30), a reference capacitive element (13) connected between the output line (30) and the ground through a switch element (17), and a plurality of infrared detection capacitive elements (12) connected between the output line (30) and the ground through switch elements (16). The series capacitive elements (14) are connected with the output line (30).
