Abstract
Official abstract text for this publication.
A 3D imaging device obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement. The 3D imaging device estimates (calculates) an ideal disparity of a main subject based on a preset viewing environment (display condition) and a distance to the main subject, and obtains a disparity (an actual disparity) of the subject (main subject) actually occurring on a virtual screen. The 3D imaging device obtains a correction disparity using the ideal disparity and the actual disparity, and adds the calculated correction disparity to the 3D image (horizontally shifts the image) to perform appropriate disparity correction. The 3D imaging device obtains a 3D image (3D video) that achieves an appropriate 3D effect and/or intended placement without being affected by a disparity occurring in the horizontal direction caused by insufficient precision (in particular, insufficient optical precision).
First claim
Opening claim text (preview).
The invention claimed is: 1. A 3D imaging device for three-dimensionally imaging a subject and capturing a 3D image formed by a left eye image and a right eye image, the 3D imaging device comprising: an imaging unit configured to capture the 3D image; a distance information obtaining unit configured to obtain distance information indicating a distance from the 3D imaging device to the subject; a condition obtaining unit configured to obtain an imaging condition under which th…
