A spectral image capturing method using a spectral camera control device installed in aircraft, the method comprising:a) setting an exposure time of the spectral camera so that a current exposure time is determined (S2),b) determining whether or not either an amount of attitude change or an amount of position change of the spectral camera per exposure time exceeds a predetermined threshold based on a spatial resolution of the spectral camera (S4),c1) when exceeding the predetermined threshold, resetting the current exposure time to be shorter (S5),c2) when not exceeding the predetermined threshold, not resetting the current exposure time to be shorter, andd) capturing a spectral image in a snapshot mode with the spectral camera using the reset exposure time,whereinwhen the transmission wavelength of the liquid crystal tunable filter is switched while the aircraft is in a stationary flight, steps b) to d) are repeated.
