In a three-dimensional image capturing apparatus (three-dimensional image processing apparatus), a depth obtainment unit obtains L depth information and R depth information from a three-dimensional image, and an image correction unit executes a smoothing process on an end part region of the subject based on the L depth information and the R depth information. As a result, the three-dimensional image processed by the three-dimensional image processing apparatus is a high-quality three-dimensional image that correctly expresses a sense of three-dimensionality and thickness in the subject and that has a low sense of a cardboard cutout effect.

A sense of three-dimensionality and thickness is restored to a subject and a high-quality three-dimensional image with a low sense of a cardboard cutout effect is obtained, regardless of the cause of the cardboard cutout effect. In a three-dimensional image capturing apparatus (three-dimensional image processing apparatus) (), a depth generation unit () obtains L depth information and R depth information from a three-dimensional image, and an image correction unit () executes a shadow enhancement process that is stronger on the inside of an object than on the outside of the object, based on the L depth information and the R depth information. Through this, the occurrence of the cardboard cutout effect can be suppressed, and a high-quality three-dimensional image with a reduced cardboard cutout effect can be obtained.

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.

In the three-dimensional imaging device (three-dimensional image processing device), the depth acquisition unit acquires L depth information and R depth information from a three-dimensional image. The image correction unit adjusts disparities of edge portion areas of a subject based on the L depth information and the R depth information such that the normal positions of the edge portion areas of the subject are farther away. Accordingly, when a three-dimensional image acquired by the three-dimensional imaging device is three-dimensionally displayed, the edge areas of the subject are displayed having a sense of roundness. As a result, a three-dimensional image that has been subjected to processing by this three-dimensional image processing device is a high-quality three-dimensional image that can appropriately reproduce the three-dimensional appearance and sense of thickness of the subject and has little of the cardboard effect.
