Imaging system and imaging method

Abstract

According to an aspect, there is provided an imaging system () for imaging of subjects. The imaging system () comprises: a spectral camera () configured to capture a spectral image of a subject () in a spectral capture period comprising a plurality of spectral time points, the spectral image comprising a plurality of spectral frames cach captured at a wavelength of a plurality of wavelengths and each corresponding to a spectral time point of the plurality of spectral time points: a reference camera () configured to capture a reference image of the subject () in a reference capture period comprising a plurality of reference time points and corresponding to the spectral capture period, the reference image comprising a plurality of reference frames each corresponding to a reference time point of the plurality of reference time points and a spectral frame of the plurality of spectral frames: a calculation unit () configured to calculate a motion vector for each reference frame of a subset of the plurality of reference frames: and an alignment unit () configured to align the spectral frames with each other by applying each calculated motion vector to the spectral frame of the plurality of spectral frames to which it corresponds. According to other aspects, there is provided an imaging method for imaging of subjects and a computer program which, when executed on a computing device, carries out a method of imaging of subjects.
