Abstract: An imaging system includes an imaging apparatus that repeatedly acquires a compressed image in which information regarding light of four or more wavelength bands from a target is compressed, and a processing apparatus. The processing apparatus extracts a partial region including a region of the target from the compressed image so as to compensate for a relative motion between the target and the imaging apparatus, and generates spectral images corresponding to wavelength bands, based on data of the partial region of the compressed image.
