Infrared sensor and method for driving the same

摘要

An infrared sensor includes a plurality of reference pixel units 2 arranged in a matrix pattern and series capacitor elements 14 provided in a one-to-one correspondence with the reference pixel units 2 . The reference pixel units 2 each include an output line 30 , a reference capacitor element 13 connected via a switching element 17 between the output line and the ground, and a plurality of infrared-detecting capacitor elements 12 connected via associated switching elements 16 between the output line 30 and the ground. Each series capacitor element 14 is connected to the associated output line 30.
