Non-flat image processing apparatus and image processing method, and recording medium and computer program

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.

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.
