Title:

INFRARED IMAGING DEVICE

Document Type and Number:

WIPO Patent Application WO/2016/185699

Kind Code:

A1

Abstract:

[Problem] To correct, with a high degree of accuracy, for fluctuations in the values for pixel signals output by an infrared sensor (3) caused by temperature variations, without causing an increase in the number of components of an infrared imaging device (1). [Solution] This infrared imaging device (1) comprises: an imaging optical system (2); an infrared sensor (3) wherein, by matching the center (31o) of the detection region (31) and the optical axis (O) of the imaging optical system, and making the length of the detection region (31) longer than the length of the imaging region (D) of the imaging optical system in one direction passing through the center (31o), an effective region (A) in which the detection region (31) and the imaging region (D) overlap, and reference regions (B) in which the detection region (31) and the imaging region (D) do not overlap, are provided within the detection region (31); and a signal correction unit (61) that corrects fluctuations in the values of pixel signals caused by temperature variations, by correcting values of pixel signals for effective pixels, which are pixels within the effective region (A), using the values for pixel signals for reference signals, which are pixels within the reference region (B).
