    摘要: The invention relates to a stereoscopic recording and display system, preferably having an autostereoscopic display system, wherein the position of the observer (especially the distance of the observer from the display system) is determined with a head tracking system and the convergence angle between the two cameras of the recording system is changed in dependence upon the distance of the observer from the display system in such a manner that, for an approach of the observer toward the system, the optical axes of both cameras are greatly convergent and, for a distancing of the observer from the display, the optical axes of both cameras are only slightly convergent. Simultaneously, the cameras are always focussed onto the intercept point of the optical axes of both cameras. By changing the convergence angle in dependence upon the distance of the observer from the display screen, either close image contents or distant image contents of the recorded scene are displayed stereoscopically depending upon the particular distance of the observer.

    摘要: An image display system for providing images such that a right eye and a left eye of an observer see different images, respectively. The image display system includes: a camera for taking a picture of said observer and then outputting an image of the observer; a pair of liquid crystal display devices transparent to light; an image generation device for generating a back-light image based on an image output signal provided by the camera; a pair of CRT devices for displaying a back-light image generated by the image generation device to illuminate the pair of liquid crystal display devices from their back sides; a mirror for combining images present on the pair of liquid crystal display devices into one image; and optical elements for giving directivity to back-light emitted by the pair of back-lighting devices so that one of the pair of CRT devices provides back-light illumination for the right eye and the other one of the pair of CRT devices provides back-light illumination for the left eye.

    摘要: An improved three dimensional display device, for a single viewer. To the apparatus of U.S. Pat. No. 5,132,839 is added a mechanism for tracking the eye motion of the viewer. Because the control system "knows" the angles at which the device must project the frame images, only two (stereoscopic) frame images need to be projected in each frame, and a more complete illusion of three dimensionality, with respect to both lateral and vertical movement of the viewer, is provided.

    摘要: An image display apparatus of head mounted type includes first and second liquid crystal display panels for displaying first and second images to be observed by right and left eyes, respectively of a user wearing the image display apparatus, an optical system for forming virtual images of the displayed first and second images such that the virtual images can be seen by the user, a controller for controlling electronically at least one of position, posture, size and shape of the first and second displayed images. The first and second images are smaller than display areas of the first and second liquid crystal display panels. In one embodiment, the controller includes a button for moving horizontally and vertically the displayed images on the display panels and a button for rotating the displayed images. In another embodiment, the controller includes a detector for detecting rotation and/or position of the apparatus and the displayed images are shifted and rotated and size or shape of the displayed images is changed such that the virtual images are seen to be stationary in a virtual image plane.

    摘要: An image processing apparatus capable of displaying an object on right and left screens so that the object an be visually examined as usually seen by the naked eye. When visual examination positions of right and left displays (1, 2) are detected by eye cameras (3, 4), the visually examined object (WK) on the screens (1, 2) is specified on the basis of the detected visual examination positions. A position of the object (WK) on one screen (1a) is fixed and an entire image including the object (WK) is shifted on the other screen (2a) so that a position of the object (WK) on the other screen (2a) becomes the same to the fixed position on the one screen (1a). A processing is performed to darken a portion of the screen (2a) which is not displayed on the screen (2a) before the image shifting and is displayed on the screen (2a) as a result of the image shifting, and also to darken a portion of the screen (1a) corresponding to the darkened part of the screen (2a) so that the corresponding part is also darkened. The display units (1, 2) are attached to a head of a visually examining operator with use of a predetermined supporting member in such a manner that distances between the screens (1a, 2a) and the operator's left and right eyes are kept constant.
