ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a stereoscopic image displaying apparatus. More specifically, the present invention relates to a stereoscopic image displaying apparatus which forms or selects a stereoscopic image desired by the user for display.
2. Description of the Background Art
An image of an area in all directions over 360° taken by a camera positioned at the center is referred to as a panoramic image or a panorama.
FIGS. 1A and 1B
are illustrations showing a method of cutting out and displaying part of conventional panoramic image data in an interactive way.
FIG. 1A
shows an example of a method of photographing to obtain panoramic image data.
FIG. 1B
shows a concept of cutting out and displaying a desired part of the panoramic image.
Referring to
FIG. 1A
, assume that a camera (subject)
32
is positioned at the center, viewing scenes therearound over 360°. Camera
32
rotates once with the direction changed, starting from position A. Accordingly, a series of planer image data Gi (i=1, 2, 3, . . . N) are obtained. Generally, overlapping portions of the data are removed and panoramic image data is obtained.
The user views the panoramic image data by using a planer display, and an image of a part, or a partial image, Ri is displayed on a planer display screen
36
, if the central image Ri of the panoramic image data has represented in
FIG. 1B
is designated by a cursor.
Thus the user can cut out and display on a planer display
36
a desired image Ri from a series of panoramic image in an interactive manner, and can enjoy panoramic view of 360° on the display screen.
Another conventional system has been known in which a selected part of a displayed planer image is enlarged and displayed as if a zoom lens is used.
Further, among image data obtained through the network such as the Internet, there are real image data obtained by photographing objects of scenes from multiple points of view as well as CG data corresponding to multiple points of view (hereinafter referred to as “multi view point image data”) in accordance with a format such as Quick Time VR (trademark of Apple Computer of the United States) or VRML (Virtual Reality Modeling Language). A system has been known which displays image data of an object or scene viewed from an arbitrary view point on an output device such as a display screen, utilizing the multi view point image data.
However, there has not been any system which displays a stereoscopic image based on existing image data such as the above described panoramic image.
SUMMARY OF THE INVENTION
Therefore, an object of the present invention is to provide a stereoscopic image displaying apparatus capable of providing a stereoscopic image display of a desired planer image, a method therefor, and a computer readable recording medium storing a program for the stereoscopic image display.
Another object of the present invention is to provide a stereoscopic image displaying apparatus capable of giving a stereoscopic display of an image of a selected portion of a planer image.
A still further object of the present invention is to provide a method of forming image data for stereoscopic display which allows formation of image data to be given as stereoscopic display, by using CG data.
A still further object of the present invention is to provide a method of forming image data for stereoscopic display which allows formation of image data to be given as binocular stereoscopic display, using CG data.
A still further object of the present invention is to provide an apparatus for forming image data for stereoscopic display, which allows formation of image data to be given as stereoscopic display, using CG data.
A still further object of the present invention is to provide an apparatus for forming image data for stereoscopic display, which allows, formation of image data to be given as binocular stereoscopic display, using CG data.
A still further object of the present invention is to provide a method of stereoscopic display which allows formation of image data to be given as stereoscopic display, using multi view point image data.
A still further object of the present invention is to provide a method of stereoscopic display which allows formation of image data to be given as stereoscopic display viewed from an arbitrary point, utilizing the multi view point image data.
A still further object of the present invention is to provide a method of stereoscopic display which allows formation of image data to be given as stereoscopic display which is free of any unnaturalness when viewed by a person, using multi view point image data.
A still further object of the present invention is to provide a method of stereoscopic display allowing formation of image data which can be given as binocular stereoscopic display.
A still further object of the present invention is to provide a stereoscopic display apparatus allowing formation of image data which can be given as stereoscopic display, using multi view point image data.
A still further object of the present invention is to provide a stereoscopic display apparatus allowing formation of image which can be given as stereoscopic display viewed from an arbitrary point, using multi view point image data.
A still further object of the present invention is to provide a stereoscopic display apparatus allowing formation of image data which can present stereoscopic image free of any unnaturalness when viewed by a person, using multi view point image data.
A still further object of the present invention is to provide a stereoscopic display apparatus allowing formation of image data which can be given as binocular stereoscopic display, using multi view point image data.
A still further object of the present invention is to provide a computer readable recording medium storing a stereoscopic display program to be executed by a computer for implementing a method of stereoscopic display allowing formation of image data tobe given as stereoscopic display using multi view point image data.
A still further object of the present invention is to provide a computer readable recording medium storing a stereoscopic display program to be executed by a computer for implementing a stereoscopic display method allowing formation of image data to be given as stereoscopic display viewed from an arbitrary point, using multi view point image data.
A still further object of the present invention is to provide a computer readable recording medium storing a stereoscopic display program to be executed by a computer for implementing a stereoscopic display method which allows formation of image data to be given as stereoscopic display free from any unnaturalness when viewed by a person, using multi view point image data.
A still further object of the present invention is to provide a computer readable recording medium storing a stereoscopic display program to be executed by a computer for implementing a stereoscopic display method which allows formation of image data to be given as binocular stereoscopic display, using multi view point image data.
The stereoscopic image display apparatus in accordance with an aspect of the present invention includes an input operating unit for designating an image of a desired portion of a planer image, and a stereoscopic display controlling unit for displaying on a stereoscopic display screen, stereo-pair images corresponding to the partial image designated by the input operating unit.
The stereo-pair images which allow stereoscopic view, corresponding to the designated partial image are generated. Therefore, the image of the desired portion of a planer image can be given as a stereoscopic image.
Preferably, the stereo-pair images maybe prepared in advance corresponding to the designated partial image.
By this structure, it becomes possible to readily display, simply by preparing in advance stereo-pair images for each of partial images of a planer image in advance, corresponding stereoscopic image on a stereoscopic display screen.
More preferably, the stereo-pair images m
