  • Patent number: 7831136
    Abstract: An ocular fundus is photographed as an electronic image via photographic stops, and the image of the photographed ocular fundus is recorded in a recording apparatus. The photographic stops are selected by moving a movable stop unit. Alignment observation or monocular photography is performed when a center photographic stop is selected. Left and right images for stereoscopic viewing are acquired when left and right photographic stops are selected. The acquired ocular fundus images are recorded in association with the position of the photographic stop used when the images were acquired. Therefore, the left image can be displayed on the left side of the monitor and the right image can be displayed on the right side by referring to the information of the photographic stop position when the left and right images for stereoscopic viewing are displayed on the monitor. This makes reliable stereoscopic viewing of the ocular fundus possible.

  • Publication number: 20090263115
    Abstract: An ocular fundus is photographed as an electronic image via photographic stops (31a, 31b and 31c), and the image of the photographed ocular fundus is recorded in a recording apparatus. Either of one of the photographic stops is selected by moving a movable stop unit (32). Alignment observation or monocular photography is performed when the photographic stop (31a) is selected. Left and right images for stereoscopic viewing are acquired when the photographic stops (31b) and (31c) are selected. The acquired ocular fundus images are recorded in association with the position of the photographic stop used when the images were acquired. Therefore, the left image can be displayed on the left side of the monitor and the right image can be displayed on the right side by referring to the information of the photographic stop position when the left and right images for stereoscopic viewing are displayed on the monitor. This makes reliable stereoscopic viewing of the ocular fundus possible.
