PROBLEM TO BE SOLVED: To provide an image processing device, an imaging apparatus and an image processing method, capable of realizing a multiband imaging system without significantly changing an existing imaging system.SOLUTION: An image processing device includes: an image acquiring unit for acquiring an image captured by an imaging element including first to third color filters; and a multiband estimating unit for setting a first band BD1 corresponding to a non-overlapping portion of a first transmittance characteristic F, a second band BD2 corresponding to an overlapping portion between the first transmittance characteristic Fand a second transmittance characteristic F, a third band BD3 corresponding to a non-overlapping portion of the second transmittance characteristic F, a fourth band BD4 corresponding to an overlapping portion between the second transmittance characteristic Fand a third transmittance characteristic F, and a fifth band BD5 corresponding to a non-overlapping portion of the third transmittance characteristic F, and estimating component values b, b, g, rand rof the first to fifth bands BD1-BD5 on the basis of pixel values of first to third colors. |
