THREE-DIMENSIONAL IMAGE CONSTRUCTION APPARATUS AND THREE-DIMENSIONAL IMAGE CONSTRUCTION METHOD
First Claim
1. A three-dimensional image construction apparatus comprising:
- a display unit displaying a first three-dimensional image on a predetermined origin surface;
an input unit receiving an input of a region of interest for a second three-dimensional image in the first three-dimensional image; and
a calculation unit setting the origin surface as an initial value of the origin of a projection line to construct the second three-dimensional image, correcting the origin of the projection line for a pixel in the region of interest based on a depth image corresponding to the first three-dimensional image, and then constructing the second three-dimensional image using the corrected origin of the projection line for the region of the interest.

Abstract
A calculation unit generates a depth image corresponding to a first three-dimensional image with respect to a region of interest and sets a first image region based on a depth gradient of the depth image. The calculation unit moves the origin of a projection line to the near side or far side in the projection line direction by an amount of movement B for a pixel in the first image region, constructs a depth image based on the moved origin of the projection line in the first image region, sets a second image region based on the depth gradient of the depth image based on the moved origin of the projection line in the first image region, sets the second image region as the first image region, and repeats these processes. Once end conditions are satisfied, the calculation unit constructs a second three-dimensional image based on the moved origin of the projection line.
