Problems solved by technology

[0008] However, conventionally, the above-mentioned publications did not specifically consider a case where real-time performance is required for synthesizing video images of high picture quality such as video images of a television set as a display device or video images from arbitrary viewpoints.
Furthermore, the above-mentioned publications do not mention a method of storing omnidirectional video images in consideration of the performance or conditions of the image display or reproduction side
Moreover, the above-mentioned publication does not consider an image storage method not only viewed from the inside in any viewpoint direction but also used from the outside.

Embodiment Construction

[0099] Embodiments of the present invention will be described below with reference to the accompanying drawings.

[0100] A. Omni-directional video image generation system

[0101] FIG. 1 schematically shows the structure of an omnidirectional video image generating system 10 for implementing the present invention. As shown in FIG. 1 , an omnidirectional video image generation system 10 includes an omnidirectional image capturing device 11 , an omnidirectional video image synthesis device 12 and an omnidirectional video image storage device 13 .

[0102] The omnidirectional image capture device 11 is configured such that N cameras are located so that they can capture video images in various directions centered on a certain spatial viewpoint. The following camera arrangement examples can be employed.

[0103] (1) A structure in which N cameras are arranged radially. For example, the pinhole cameras are each located on the constituent faces of a polyhedron such as a regular d...

Abstract

Such processes as compression, storage and reproduction of an image mapped on a three-dimensional coordinate system such as a spherical surface or a cylindrical surface are performed suitably by mapping omnidirectional map information to a two-dimensional image such that the redundancy may be low while the amounts of information is kept equal as far as possible with minimized errors. Preferably, the image is converted into a two-dimensional image in a form determined taking the performance of the omnidirectional video image reproduction side into consideration. The technique can be utilized when mapping information which describes a corresponding relationship between the three-dimensional coordinate system of the original omnidirectional image and the mapped two-dimensional image coordinate system is produced to synthesize an omnidirectional video image from an arbitrary viewpoint direction.

Description

technical field [0001] The present invention relates to an image processing device, an image processing method, a storage medium, and a computer program in which processing such as compression, storage, and reproduction are performed on video image data captured by a video camera. More specifically, the present invention relates to an image processing device, an image processing method, a storage medium, and a computer program in which operations such as compression, storage, and reproduction are performed on an image formed by splicing video image data captured by a plurality of cameras. deal with. [0002] More specifically, the present invention relates to an image processing device, an image processing method, a storage medium, and a computer program in which operations such as compression, Storage and reproduction processing. More specifically, the present invention relates to an image processing apparatus, an image processing method, a storage medium, and a computer pr...
