摘要： Upon observation of multi-viewpoint images, even when the viewpoint moves continuously, the image cannot normally be displayed in correspondence with the continuous movement of the viewpoint, and an image from a viewpoint closest to the current viewpoint is displayed. To prevent this, each two adjacent images of the multi-viewpoint images are interpolated by detecting corresponding pixels and generating an interpolated image in accordance with the correspondences among pixels. The interpolated image is generated in such a manner that an epipolar plane image is generated by juxtaposing corresponding lines of the multi-viewpoint image, straight lines are detected from the epipolar plane image, and the intersecting points between interpolated lines and the detected straight lines are detected as interpolated pixels. In this case, as for a point for which a straight line cannot be detected, a straight line passing the point is estimated, thereby generating an interpolated pixel. When a plurality of straight lines are detected for a pixel of interest, the priority level is assigned to the pixel of interest in correspondence with the number of detected straight lines. When the priority level is smaller than that of another pixel through which the detected straight line passes, the straight line is ignored, and an interpolated pixel is not generated.

摘要： Images picked up by a plurality of cameras are corrected and projected on a single plane. The input images are converted to projected images on a reference projection plane in accordance with reference parameters and camera parameters. Then images of an area of nx.times.ny whose center is an intersection B that is a perpendicular from a center of a lens of a m-th camera on the reference projection plane are extracted from the projected images. By extracting the area as described above, there is obtained an image which can be assumed that optical axes of each camera intersects perpendicular to the reference projection plane and the optical axes are parallel to each other. Therefore, when an epipolar plane is constructed during an image interpolation process, corresponding points form a straight line on the epipolar plane, thus it becomes easier to detect the corresponding points.

摘要： There is disclosed a mixed reality presentation apparatus which generates and displays a three-dimensional virtual image on a see-through display device so as to allow a plurality of players to play a multi-player game in a mixed reality environment. The apparatus has a CCD camera for detecting the mallet positions of the plurality of players, and a sensor for detecting the view point position of each player in the environment of the multi-player game. The apparatus generates a three-dimensional virtual image that represents a game result of the multi-player game that has progressed in accordance with changes in mallet position detected by the CCD camera and is viewed from the view point position of each player detected by the sensor, and outputs the generated image to the corresponding see-through display device. The apparatus determines the motion of each player by detecting infrared rays output from the corresponding mallet on the basis of an image captured by the CCD camera. The view point position detected by the sensor is corrected by specifying the marker in an image obtained by a camera attached to the head of each player, and comparing the marker position in that image with an actual marker position.
