Abstract

A stereoscopic video image pick-up and display system having a stereoscopic video image pick-up device including two video image pick-ups for outputting video information from the pick-ups; a stereoscopic video image display device for displaying different video images; and a medium for transmitting the video image information from the stereoscopic video image pick-up device to the stereoscopic video image display device. The stereoscopic video image pick-up device includes a cross-point measuring device for measuring CP information on the cross-point (CP) of optical axes of pick-ups and outputs information including the CP information and video image information to the medium. The stereoscopic video image display device includes an offset presetting device for offsetting and displaying different video images based upon the video image information, the cross-point information and information on the size of the image which is displayed by the stereoscopic video image display device.

- - 2. A stereoscopic video image display system as defined in claim 1 wherein said stereoscopic video image display device includes viewer'"'"'s position information measuring means for measuring information on the position of a viewer relative to a display screen, and further includes offset presetting means for offsetting and displaying said different video images based upon said video image information, said cross-point information, information on the size of the image which is displayed by said stereoscopic video image display device and the information on the position of the viewer.
  - 3. A stereoscopic video image pick-up and display system as defined in claim 2 in which a viewer'"'"'s position detecting means is disposed integrally with the main body of said stereoscopic video image pick-up and display system.
  - 4. A stereoscopic video image pick-up and display system as defined in claim 3 in which a viewer'"'"'s position detecting means includes an ultrasonic wave transmitter and ultrasonic wave receiver.
  - 5. A stereoscopic video image pick-up and display system as defined in claim 3 in which a viewer'"'"'s position detecting means detects the position based upon the picked-up image of the viewer.
  - 6. A stereoscopic video image pick-up and display system as defined in claim 2 in which a viewer'"'"'s position detecting means is disposed in a position remote from the main body of said stereoscopic video image pick-up and display system.
  - 7. A stereoscopic video image pick-up and display system as defined in claim 1 in which said cross-point measuring means calculates the cross-point position based upon the angle of the intersection of the optical axes in said two pick-up means.
  - 8. A stereoscopic video image pick-up and display system as defined in claim 1 in which said cross-point measuring means calculates the cross-point based upon the position of picking-up of an object in said two pick-up means which are disposed in a parallel relationship.
  - 9. A stereoscopic video image pick-up and display system as defined in claim 1 in which said stereoscopic video image pick-up device is adapted to feed out information on the depth of an area, the image of which is picked-up in a depth direction andsaid stereoscopic video image display device includes offset presetting means for offsetting and displaying said different video images based upon said video image information, said cross-point information, information on the size of the image which is displayed by said stereoscopic video image display device and the information on the position of the viewer.
  - 10. A stereoscopic video image pick-up and display system as defined in claim 1 in which said offset presetting means presets the offset of the right-eye and left-eye video images based upon the information input to a input means for adjusting the stereoscopic feeling of the image which is displayed by a display means.
  - 11. A stereoscopic video image pick-up and display system as defined in claim 1 in which said system includes a memory for the left-eye video image for storing a left-eye video image and a memory for the right-eye video image for storing a right-eye video image,said offset presetting means includes timing control means for controlling the timing of the read-out of video image data from a frame memory for left-eye video image and/or a frame memory for right-eye video image;
    - andsaid timing control means presets the offset of said left-eye video image and right-eye video image by advancing or delaying the timing of the read-out of the video image data from one of said frame memories for left-eye and right-eye video images relative to the timing of the read-out of the video image data from the other of said from memories for the left-eye and right-eye video images.
  - 12.
