摘要： Each of the panoramic images corresponding to a plurality of positions of a viewpoint is compressed and stored as partial images obtained by dividing each panoramic image by a predetermined field of view. The panoramic image has a field of view wider than a display field of view of an image to be displayed on a display unit. A partial image containing an image to be reproduced is selected based on the information about the position and the direction of a viewpoint and the display field of view, and an image corresponding to the position and the direction of a viewpoint is generated and displayed from the selected partial image. Thus, when virtual space in the walk-through system is designed using the IBR technology, stored image data can be efficiently reproduced.

摘要： There is disclosed an image data encoding/decoding method and apparatus which can efficiently encode multi-viewpoint image data obtained by sensing a single object from many viewpoints, and can obtain decoded data in units of pixels at high speed. Reference images which are not encoded are set every predetermined number of images (S701), and encoding is done using only the relationship with this reference image. An orthogonal transform is used in encoding, and an inverse transform formula for each pixel in a block is expanded and stored upon computing the orthogonal transform (S704). The coefficients after the orthogonal transform are fixed-length encoded in units of pixels (S705). Upon decoding, fixed-length encoded data corresponding to desired pixels are decoded, and pixel data are decoded by substituting coefficients obtained by decoding in the expansions generated upon encoding.

摘要： In an image reproducing method capable of displaying annotations in virtual space constituted by a group of real panoramic images, if an object for which an annotation is to be displayed falls within the field of view at the position of the observer, the object is adopted as the display position of the annotation. If the object is not within the field of view, then the direction of forward travel of the observer is adopted as the annotation display position. If the object is in a state of transition, then the annotation display position is decided by interpolation.
