The stereoscopic image display device comprises an infrared light synchronization signal radiator for visual field opening/closing and is configured to radiate polarized infrared light used as a basis for tilt correction by attaching an infrared polarizing filter along the infrared light synchronization signal radiator for visual field opening/closing as a basis for tilt correction of stereoscopic image appreciation eyeglasses or separately by installing a polarized infrared light radiator for tilt correction.

Stereo camera

A stereo camera optimally corrects a parallax despite a photographing distance. Lens boards of right and left photographing lenses are mounted with slide guides for obliquely feeding in an inter-optical axis distance approaching direction as the lens boards are fed. When a focusing knob is rotated, the photographing lenses and a finder lens are integrally advanced or retracted in response to the rotating direction of a cam shaft.

A virtual field-of-view frame (defined as a reference window) is set in a field of view of a stereo camera configured of paired imaging units each configured of a shooting lens and an imaging pickup device placed on left and right in parallel to each other, and 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. Image data of an image of the reference window (in the window) formed on the left and right image pickup devices is read, and stereoscopic video data (defined as standard stereoscopic video data) is sent. On a display side, the standard stereoscopic video data is displayed with an electronic display on a display screen (a screen having the positions of left and right screens exactly matching each other and having the position and size for reproducing and displaying the reference window in full size is defined as a reference dimension display screen) equivalent to the reference window, simultaneously with left and right polarizations orthogonal to each other or circular polarizations in counterclockwise and clockwise directions or alternately with linear polarization in a same direction in a time-division manner. With eyeglasses for field-of-view separation corresponding to the polarizing scheme, left and right videos are separately viewed.

Stereo camera

A stereo camera optimally corrects a parallax despite a photographing distance. Lens boards of right and left photographing lenses are mounted with slide guides for obliquely feeding in an inter-optical axis distance approaching direction as the lens boards are fed. When a focusing knob is rotated, the photographing lenses and a finder lens are integrally advanced or retracted in response to the rotating direction of a cam shaft. The slide guides are so disposed that the right and left visual fields are brought into agreement at a close distance at the close distance photographing and the right and left visual fields are brought into agreement at the close distance as compared with the focal distance at the time of remote distance photo-graphing. Accordingly, the unnatural of the remote or close distance feeling generated by the influence of the close distance subject at the human collimation at the time of remote distance photographing, and ideal stereo effect is obtained at all the photographing distances.

Stereoscopic Camera

A stereoscopic camera for stereoscopic photography, which reduces losses in the screen when taking a picture in a close range and provides optimum stereoscopic effect without the need of adjusting the distance between the slides that are being mounted. A camera body is furnished with reflex finders constituted by a pair of right and left photographing lenses and pentaprisms. The distance between optical axes of the photographing lenses is adjusted by a horizontal shifting mechanism. Focusing plates of the right and left finders are marked with vertical lines at the centers and on the right and left sides thereof. The distance between optical axes is adjusted depending upon the distance to the subject and vertical lines of the right and left focusing plates are brought into agreement. Then, the right and left photographing areas are nearly brought into agreement on the real screen and no loss occurs on the screen.

Right and left lens boards (42R, 42L) of a stereo camera (41) are coupled to a camera body (46) via upper and lower two sets of parallel links (47) . Parallel grooves (45L, 45R) are formed in the lateral direction in the inner portions of the lens boards (42L, 42R), and with which a circular eccentric cam (43) is engaged. When the shaft mounting the cam (43) is turned, the right and left lens boards (42R and 42L) move in parallel describing circular loci, making it possible to automatically adjust the focal point as well as the distance between the optical axes of the lenses, which is important for accomplishing a stereo effect.

Stereoscopic image appreciation eyeglasses with liquid crystal cell voltage control and stereoscopic image display device

An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. The problem with the occurrence of crosstalk is solved. Stereoscopic image appreciation eyeglasses have polarizing plates, visual field opening/closing liquid crystal cells and tilt correcting liquid crystal cells. The synchronization signal is received by a receiver mounted on an eyeglass frame. The tilt correcting liquid crystal cells are adjusted by a voltage based on the eyeglass frame tilt angle detected.

Lens adjustment device of stereo camera

A lens adjustment device of a stereo camera of this invention operates adjustment rings of right and left lenses of an optical axis distance variable type stereo camera in the interlocking arrangement with each other. Crank arms are provided on stop adjustment rings of lenses mounted on the right and left lens boards capable of adjusting the distance between the optical axes. The right and left crank arms are disposed in symmetry of rotation at 180°. The center of a lever in a vertical direction is fitted to a shaft on a slide frame. The upper end portion of the lever and one of the crank arms are interconnected by a link, while the lower end portion of the lever and the other crank arm are interconnected by another link. When the distance between the optical axes of the right and left lenses is changed by an adjustment mechanism for adjusting the distance between the optical axes, the lever rotates while the stop adjustment rings are kept fixed. When one of the stop adjustment rings is rotated either to the right or the left, the other adjustment ring, too, is rotated in the same direction and at the same angle through the links and the lever, so that stop adjustment of the right and left lenses operates in the interlocking arrangement irrespective of the change of the distance between the optical axes of these lenses.
