    摘要: Several different methods alone or in combination can be used to reduce image jump or stutter. The image plane on which the original image is taken can be mechanically or electronically rotated about a point of rotation in the scene. The number of original images which are viewed could be increased by interpolation. The subtended viewing angle of the viewpoints can be reduced and viewpoints within the subtended viewing angle can be increased by interpolation. Reduced subtended viewing angle images can be created for each eye. The depth of focus of the images can be changed by identifying the images that jump and blurring the images outside the area of interest. The original images can be processed to move the image plane further back from the objects in the scene. Some of the images ordinarily existing between the right and left eye perspectives can be eliminated. The objects in the background of the scene being photographed can be identified and shifted forward in the scene. The highest detail volume of the images can be identified and the images can be processed to rotate around the volume. The highest detail area can be identified and the original images processed to displace the images to minimize the movement of the highest detail area. The original images can be viewed and a point within each image identified to align the point from view to view using a linear or other transformation.

    摘要: A display concept designed to interface with source material from a computer, video recorder or video camera. The interface to a computer generates a series of images that are separate viewpoints of a desired scene to be viewed in three dimensions. The images are based upon a horizontal translation of viewpoints. In the case of a video camera, the interface captures video images from multiple viewpoints and delivers these images in a successive manner to a location at which they can be viewed. The camera requires a single lens and sensor instead of multiple lenses. In the video recorder case, an interface stores images from a computer or video camera and plays back images in the proper sequence for the display. A display system can also operate as a film recorder to provide hard copy, three-dimensional images. A computer, video recorder or video camera thus provides images to a surface which can be viewed and which can present two-dimensional images which are changeable into three-dimensional images. In this way, the output from a computer, video recorder or a video camera can be used to store images and to play back the images in the proper sequence for a three-dimensional display.

    摘要: The improved method and apparatus for recording a stereoscopic image read a plurality of original images photoelectrically, split each original image into linear images of a desired pitch, perform any necessary image processing operations such as arranging the linear images in the recording order, and record the linear images by scan exposure on a lenticular light-sensitive material having a lenticular sheet and a recording layer. The method and apparatus permit the lenticular light-sensitive material to be scan exposed from the rear side and they also enable the linear images to be recorded with increased line width and a stereoscopic image to be formed with satisfactory registration between the principal objects of the original images. The improved lenticular light-sensitive material has an anti-halation layer provided between the lenticular sheet and the recording layer, thus permitting scan exposure to be effected from the rear side. According to the present invention, stereoscopic images of high quality that have no perceivable unnaturalness such as flickers can be recorded with great ease and at any desired magnification.

    摘要: A stereoscopic image of an object is focused on an image pickup device based on the degree to which left and right images of the object are coincident on the image pickup device. Signals produced by the image pickup device that represent the left and right images are compared with each other to develop a control signal that indicates the coincidence of the left and right images on the image pickup device, and the spacing between the image pickup device and an optical element that directs the images onto the device is changed in response to the control signal to increase the coincidence. Two alternative types of comparison are performed, each of which indicates the degree of coincidence (and hence the quality of focus) of the left and right images on the image detector. In one approach, the left and right images are compared to determine their cross correlation on the image pickup device, and the spacing is changed to maximize the correlation. Alternatively, the comparison determines the difference between the left and right images on the image pickup device, and the spacing is changed to minimize the difference. The focusing technique is useful in, e.g., the optical system of an endoscope. Rangefinding and videometry are also performed to determine the distance to the object being viewed, as well as its position and size.
