    摘要： An image processing method according to an embodiment of the present invention has the following steps: the multi-viewpoint image input step for inputting images obtained from a plurality of viewpoint positions arranged on different straight lines, the detection step (2, 7, 17, 8) for detecting a viewpoint position and its view direction in which a user is seeing at the viewpoint position, and the image generation step (11, 12, 13, 8) for generating a virtual image viewed from the predetermined viewpoint by using the images input in the multi-viewpoint image input step on the basis of the detected predetermined viewpoint position and the view direction. In the image generation step, optimal corresponding points are obtained by detecting a straight line having a width on an epipolar plane image corresponding to the input images, thereby generating an image.

    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.
