The corrected image generation unit performs an inverse frequency transform for the deconvolution processing result, generating an output image.

Output colors corresponding the input fundamental stimulus values and spectral auxiliary coefficients are calculated. An image size corresponding to the spectral auxiliary coefficient is smaller than that corresponding to the fundamental stimulus.
