Abstract
A three-dimensional image processing device for performing image correction processing on a three-dimensionally-viewed image includes a conversion unit and a composition unit. The conversion unit generates a converted image by performing tone conversion on a pixel value in an object included in the three-dimensionally-viewed image based on a relationship between a pixel value of a pixel of interest that is a processing target and a pixel value of a peripheral pixel of the pixel of interest. The composition unit synthesizes an n-th pixel in a first viewpoint image included in the three-dimensionally-viewed image and a corresponding pixel in a second viewpoint image included in the three-dimensionally-viewed image with a distribution ratio that is based on a subject distance of the n-th pixel. The corresponding pixel is located in the same spatial location as the n-th pixel.
