Claim:
1. An image processing apparatus comprising: an initial solution generating unit configured to generate an initial solution of a restored image and an initial solution of a transmittance distribution; and an iterative processing unit configured to receive input data of the generated initial solution of the restored image and input data of the generated initial solution of the transmittance distribution, and to repeat updating of one of the transmittance distribution and the restored image, using the transmittance distribution and the restored image, in such a way as to alternate the updating of the transmittance distribution with the updating of the restored image independently for each pixel, wherein a relationship between logarithms of the transmittances obtained from the transmittance distributions in the color channels is such that the logarithm thereof in one color channel is multiplied by a constant thereby to match the logarithm thereof in another color channel.
