Abstract:
1. A three-dimensional imaging device configured to output first and second viewpoint images due to a pupil division on a light flux from a single imaging optical system, comprising: a calculation unit configured to calculate a defocus amount at each position in the first and second viewpoint images; a restoration filter storage configured to store restoration filters corresponding to the defocus amount and an image height at each position in the viewpoint images, the restoration filters being deconvolution filters based on a point image intensity distribution representing an imaging performance of the imaging optical system; and a restoration unit configured to select a restoration filter, which corresponds to the defocus amount and the image height at each position in the viewpoint images, for each position in the first and second viewpoint images, and to restore the first and second viewpoint images by performing a deconvolution for each position in the first and second viewpoint images based on the selected restoration filter.
