摘要： The present invention provides a method of generating a virtual viewpoint video image when the virtual viewpoint position is not located on a plane where a camera is disposed. In an environment in which a plurality of cameras having a horizontal optical axis are disposed in a real zone (for example, on the circumference) which surrounds an object, a video image of an arbitrary viewpoint on the circumference is generated. Further, by synthesizing video images photographed by a camera, a free viewpoint video image is generated from a virtual viewpoint (viewpoint from a high or low position) where no camera is placed. According to a method of achieving this, a travel distance of a display position is calculated by the local region synthesizing portion and this travel distance is reflected to the free viewpoint video image of a local region.

摘要： The present invention relates to color correction of video signals from a plurality of cameras. The apparatus has a correction order that defines a plurality of camera pairs and an order of the camera pairs, where each camera pair specifies a reference camera and a target camera. In the correction order, each camera is treated as a target camera at least one time, and the reference camera is treated as the target camera in a previous camera pair except for the first camera pair. The apparatus corrects a value of each pixel in a target image captured by the target camera based on a reference image captured by the reference camera, and replaces the target image by the corrected target image, for each camera pair in accordance with the order of the camera pairs.

摘要： A plurality of cameras is placed so that those optical axes become parallel to the Z-axis and are in relative position t on the XY plane. Multi-view video compression coding apparatus determines depth distance Z and unit normal vector (nx, ny, nz) of the arbitrary point in the surface of the object, moves the first block by disparity vector based on t and Z, transforming the first block by linear transformation matrix based on t, Z and n, then, matching the first block to block of the second picture. Then, while changing Z and n arbitrarily, the second block of the second picture which is most similar to the first block is searched for. And the apparatus derives a prediction error between the first block and the second block, codes the prediction error, and adds Z and n to coded data.
