INFRARED IMAGING DEVICE AND FIXED PATTERN NOISE CORRECTION METHOD

摘要

Provided is an infrared imaging device including: an infrared lens (11) for collecting infrared rays; an infrared sensor (12) for detecting the collected infrared rays; and an image signal output unit (18) which removes a fixed pattern noise from of each pixel from the output signal from the infrared sensor (12) so as to obtain an image signal. The infrared imaging device further includes: a sensor field-of-view control unit (13) which varies the field of view of the infrared sensor (12) against the infrared rays incident into the infrared sensor (12); and an entire system control unit (16) which obtains a fixed pattern noise for each pixel according to the luminance of the output signal from the infrared sensor (12) when the field of view of infrared sensor (12) is varied.
