Title:
IMAGE PROCESSING DEVICE, IMAGE PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/119751
Kind Code:
A1
Abstract:
An image processing device according to the present embodiment is provided with: a thermal image data acquisition unit (160) which acquires thermal image data captured by an infrared camera (200); a correction unit (177) which generates shutterless corrected image data by correcting, on the basis of the ambient temperature of the usage environment of the infrared camera (200) and calibration data that has been acquired in advance, first thermal image data captured by the infrared camera (200) in a state in which the shutter thereof is closed; a noise component extraction unit (173) which, on the basis of the shutterless correction image data, extracts a noise component that changes over time; and a noise elimination unit (178) which eliminates the noise component of second thermal image data captured by the infrared camera (200) in a state in which the shutter thereof is open.
