A stereo slide mount is divided into a base frame 21 and a cover frame 22 in order to facilitate the operation for mounting the stereo slide and to improve correctness. The size of the windows of the base frame is equal to the size of the pictures of the films, and pins 25 are provided at four corners of the windows to engage with perforations of the film. The cover frame 22 has holes 26 that correspond to the pins 25 and can be fitted to the base frame. The cover frames 22 are prepared in plural kinds (#0, #1, --) in which the width C.sub.1 between the windows is equal to the width between the windows in the base frame, and the width W of the windows decreases stepwisely. Plural kinds of masking-amount guide devices 31 having the same size of windows as that of the cover frames and having a collimation pattern at the same position on the right and left windows, are successively and temporarily fitted to the base frame 21, and the image of the stereo slide films is observed using a stereo slide viewer. The films are mounted on the base frame by using a cover frame of the same number as the number (#) of the masking-amount guide device 31 with which the sense of distance to the subject in a close-range view is in agreement with the sense of distance to the collimation pattern 35. There is thus obtained a stereo image with the parallax being suitably corrected.
A stereo slide mount for mounting a stereo slide film photographed by using a stereo camera said stereo slide mount comprising a base frame having two rectangular windows arranged in parallel and a plurality of cover frames each having two rectangular windows arranged in parallel, positioning pins provided on the film-mounting surface of said base frame to bring the pictures of two pieces of slide films into agreement with the windows upon engagement with perforations of the slide films that are to be fixed, holes corresponding to said positioning pins are formed in the film-holding surface of said plurality of cover frames, and said positioning pins are fitted to said holes in order to join said base frame and one of said plurality of cover frames together, and wherein said plurality of cover frames are prepared wherein a width between a right window and a left window in said plurality of cover frames is the same as a width between the windows in said base frame but the width of said plurality of cover frame windows gradually decreases relative to the width of pictures of the films, and a cover frame is selected and is joined to the base frame, making it possible to adjust shielding areas on the right and left outer sides of the stereo slide films.
A stereo slide mount for mounting a stereo slide film photographed by using a stereo camera said stereo slide mount comprising a base frame having two rectangular windows arranged in parallel and a cover frame having two rectangular windows arranged in parallel, positioning pins provided on the film-mounting surface of said base frame to bring the pictures of two pieces of slide films into agreement with the windows upon engagement with perforations of the slide films that are to be fixed, holes corresponding to said positioning pins are formed in the film-holding surface of said cover frame, and said positioning pins are fitted to said holes in order to join said base frame and said cover frame together, wherein a plurality of framing masks are prepared each having a rectangular window at the center thereof and having engaging holes that engage with the positioning pins of said base frame and having a positional relationship between said engaging holes and a vertical side of the windows which is the same as a positional relationship between a film perforation and a vertical side on the inside of the picture of the stereo slide film, and each of said plurality of framing masks having respective widths of window which becomes gradually smaller than the width of the picture of the slide film, and wherein a respective framing mask is selected and is overlapped on the slide films on said base frame, and the cover frame is fitted to the base frame, making it possible to adjust shielding areas on right and left outer sides of the stereo slide films.
