摘要： There is provided an image processing apparatus for describing a real image as a virtual object using space data formed based on a photo image of the real object, and generating a virtual image of the virtual object using the space data. The image processing apparatus captures the photo image of the real object from a real camera viewpoint position while illuminating the real object by an illumination light source placed at a real illumination position. The captured photo image is converted into space data in the form of an object for each pixel, and the space data is stored in a memory together with various illumination conditions at the real illumination position to allow a search at a later time.

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： There is disclosed a progressive display method upon rendering and displaying a virtual object expressed by RS data. When RS data is generated and recorded on the basis of real image data, map data that represents correspondence between a real image space and ray space is divided into a plurality of layers, and the resolutions of the individual layers are hierarchically changed, thus storing hierarchical map data. Upon rendering a virtual image from an arbitrary viewpoint position, rendering is done by looking up the hierarchical map data in turn in ascending order of resolution. Also, there are disclosed a downloading method of selectively downloading RS data and VRML data, and a rendering method of downloaded data. RS data with high resolution is stored in an external memory, and VRML data having a required memory size is stored in an internal memory. In principle, a virtual image is generated by rendering RS data to allow the user to experience the virtual space. When downloading of RS data is not in time, an image rendered based on VRML data is displayed.

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.
