摘要： According to embodiments, a stereoscopic image generation apparatus for generating a disparity image based on at least one image and depth information corresponding to the at least one image is provided. The apparatus includes a calculator, selector and generator. The calculator calculates, based on the depth information, evaluation values that assume larger values with increasing hidden surface regions generated upon generation of disparity images for respective viewpoint sets each including two or more viewpoints. The selector selects one of the viewpoint sets based on the evaluation values calculated for the viewpoint sets. The generator generates, from the at least one image and the depth information, the disparity image at a viewpoint corresponding to the one of the viewpoint sets selected by the selector.

摘要： According to an embodiment, an image processing apparatus includes an acquisition unit, a setting unit, a transform unit and a generation unit. The acquisition unit is configured to acquire a parallax value of each pixel of a plurality of images having a parallax. The setting unit is configured to set at least one reference range within a range of the parallax value. The transform unit is configured to apply transform to the parallax value of each pixel so as not to change a parallax value belonging to the reference range but to change a parallax value that does not belong to the reference range without changing a magnitude relationship between the parallax values of the pixels. The generation unit is configured to generate a parallax image from the image based on the parallax values after applying the transform.

摘要： According to an embodiment, an image processing device includes: a first acquiring unit, a second acquiring unit, a first setting unit, a second setting unit, a first calculating unit, and a second calculating unit. The first acquiring unit acquires a plurality of captured images by imaging a target object from a plurality of positions. The second acquiring unit acquires a provisional three-dimensional position and a provisional size. The first setting unit sets at least one search candidate point near the provisional three-dimensional position. The second setting unit sets a search window for each projection position where the search candidate point is projected, the search window having a size. The first calculating unit calculates an evaluation value that represents whether or not the target object is included inside the search window. The second calculating unit calculates a three-dimensional position of the target object based on the evaluation value.
