Title:
SPECTRAL IMAGE ACQUISITION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/110952
Kind Code:
A1
Abstract:
In the present invention, for the purpose of generating a spectral image for which positional displacement is suppressed in accordance with the movement of a subject, this spectral image acquisition device (1) comprises: a line spectral image acquisition unit (7) that acquires a plurality of line spectral images; a frame image acquisition unit (6) that acquires a 2D frame image which includes the image pickup range used by the line spectral image acquisition unit (7) and includes fewer color signals than the line spectral images; a comparison image estimation unit that estimates a comparison image for each line on the basis of each line spectral image acquired by the line spectral image acquisition unit (7) and the wavelength characteristics of the frame image acquisition unit (6); a line spectral image positional displacement detection unit that detects the amount of positional displacement between each comparison image estimated by the comparison image estimation unit and a correspondence position within the frame image; and a positional displacement correction unit that, on the basis of the positional displacement amount detected by the line spectral image positional displacement detection unit, applies each line spectral image used for estimating each comparison image to the correspondence position within the frame image.
