Three-dimensional video image pick-up and display system

A stereoscopic video imaging apparatus wherein one reference window, which is a virtual field-of-view frame, is set in a field of view of a stereoscopic video imaging apparatus in which imaging units each formed of a shooting lens and an image pickup device are placed on left and right in parallel to each other;

• and in a state in which the reference window is projected in a reduced manner by the left and right shooting lenses to form an image on each of the left and right image pickup devices, the left and right image pickup devices are placed in accordance with a width of each of left and right projected images of the reference window or stereoscopic left and right image data equivalent to the width of the projected image of the reference window is read and sent as standard stereoscopic video data.

A stereoscopic video displaying apparatus, which is an apparatus on a display side of a system in which one reference window, which is a virtual field-of-view frame, is set in a field of view of a stereoscopic video imaging apparatus in which imaging units each formed of a shooting lens and an image pickup device are placed on left and right in parallel to each other;

• in a state in which the reference window is projected in a reduced manner by the left and right shooting lenses to form an image on each of the left and right image pickup devices, the left and right image pickup devices are placed in accordance with a width of each of left and right projected images of the reference window or image data equivalent to the width of the projected image of the reference window is read and sent as standard stereoscopic video data;
• and stereoscopic video is displayed based on the standard stereoscopic video data, wherein display is made at same left and right arbitrary positions in left and right field-of-view widths within a left view angle determined by lines connecting both ends of a reference dimension display screen and a left eye of an observer and a right view angle determined by lines connecting both the ends of the reference dimension display screen and a right eye thereof.

A stereoscopic video displaying apparatus, which is a mono projector that projects an image on an electronic display onto a screen by a projection lens, wherein left and right images are alternately projected and displayed in a time-division manner onto the screen based on standard stereoscopic video data, the apparatus having externally coupled thereto an infrared-ray sending apparatus for synchronization.

A stereoscopic television camera, wherein left and right stereoscopic videos are alternately displayed in a time-division manner for viewing at a position near a distance of distinct vision in an overlap display range on a stereoscopic monitor of LCD mode of a stereoscopic television camera. Simultaneously, an infrared-ray sending apparatus for synchronization is included, and an observer further mounts a liquid-crystal plate immediately before eyeglasses including a polarizing plate in a direction orthogonal to a polarizing direction of the LCD monitor of the camera and alternately applies a voltage to the liquid-crystal plate of the eyeglasses in synchronization with an infrared rays to observe the stereoscopic videos displayed on the LCD monitor, the camera allowing direct viewing of an actual surrounding scene at the time of shooting.

A stereoscopic video displaying apparatus in which an LCD or an electronic display, such as an organic EL, is placed at a position at a distance shorter than a distance of distinct vision on a box having liquid-crystal eyeglasses with layered diopter-adjusted eyeglasses or liquid-crystal shutter eyeglasses fixed thereto;

• left and right videos of stereoscopic video are alternately displayed in a time-division manner on the display;
• and the liquid-crystal eyeglasses or the shutter eyeglasses are opened and closed in synchronization with respect to the left and right videos for separate viewing of the left and right videos for two-eye stereoscopy, wherein stereoscopic videos are alternately displayed in a time-division manner with a width in a left view angle determined by lines connecting both ends of a reference dimension display screen and a left eye of an observer and in a right view angle determined by lines connecting both the ends of the reference dimension display screen and a right eye of the observer. Thus, the left and right videos are displayed at a position where they partially overlap each other, thereby allowing the stereoscopic video equivalent to the reference dimension display screen to be viewed.

A stereoscopic video displaying apparatus in which an LCD or an electronic display, such as an organic EL, is placed at a position at a distance longer than a distance of distinct vision on a box having liquid-crystal eyeglasses or liquid-crystal shutter eyeglasses fixed thereto;

• left and right videos of stereoscopic video are alternately displayed in a time-division manner on the display;
• and the liquid-crystal eyeglasses or the shutter eyeglasses are opened and closed in synchronization with respect to the left and right videos for separate viewing of the left and right videos for two-eye stereoscopy, wherein the stereoscopic video is alternately displayed in a time-division manner with a width in a left view angle determined by lines connecting both ends of a reference dimension display screen and a left eye of an observer and in a right view angle determined by lines connecting both the ends of the reference dimension display screen and a right eye of the observer. Thus, the left and right videos are displayed at a position where they partially overlap each other, thereby allowing the stereoscopic video equivalent to the reference dimension display screen to be viewed.

A stereo slide and stereo photo print fabricated with two left and right screens integrally placed side by side from standard stereoscopic video data, wherein with a human interpupillary distance being taken as B, a distance to a reference dimension display screen D0 being taken as L0, and a view distance of the stereo photo print or the stereo slide being taken as an arbitrary distance L2,

• the screens are disposed with a spacing between the left and right screens, DP2, determined by an equation of DP2=B(1−L2/L0).
