摘要： In an ophthalmic measuring method, a traceable marker in particulate form is administered to the lachrymal fluid of a subject's eye, and the lachrymal fluid is irradiated with illuminating light. Images of the illuminated lachrymal fluid are electronically captured respectively at different times. Two images from among the captured images are selected, with each of the two selected images displaying the traceable marker. A characteristic point of each of the two selected images is specified. A movement speed of the traceable marker is measured based on positions thereof in the two selected images and on a time difference from specifying the characteristic point of one of the two selected images to specifying the characteristic point of the other of the two selected images. The measured movement speed of the traceable marker is outputted as the movement speed of the lachrymal fluid of the subject's eye.

摘要： An ophthalmologic examination apparatus is provided which is capable of performing a variety of ophthalmologic examinations with a low-cost configuration. An illuminating optical system for illuminating an eye fundus and an imaging optical system for imaging the illuminated eye fundus, which are both necessary in an ophthalmologic examination, are housed in a main unit. A plurality of attachment units is removably mounted to the main unit. Each of the attachment units is provided with a different ophthalmologic function such as a function for planarly or stereographically observing or photographing the imaged eye fundus, a function for emitting stimulating light on the eye fundus or a function for spectroscopically analyzing the eye fundus. Such an arrangement allows the ophthalmologic examination apparatus to perform various functions merely by selecting the attachment unit and mounting it to the main unit.

摘要： An imaging system is provided that is capable of controlling a photographic operation to provide favorable images of a fundus of an eye to be examined. When a normal photographic mode is selected, a single operation of a shutter button causes a single trigger signal to be generated. On the other hand, when a stereo photographic mode is selected, a single operation of a shutter button causes two trigger signals to be generated in succession. The generated trigger signal triggers a switching device so that a position of a photographic stop is automatically switched to a position predetermined for the photographic mode, and the photographic light source is caused to emit light a number of times that corresponds to the selected photographic mode. In such a configuration, fundus images are automatically produced a set number of times by a single operation of the shutter. Therefore, a high-quality fundus image can be obtained without concerns that an appropriate moment to capture an image will be missed.
摘要翻译：提供一种成像系统，其能够控制摄影操作以提供要检查的眼睛的眼底的有利图像。当选择正常拍摄模式时，快门按钮的单次操作导致产生单个触发信号。另一方面，当选择立体摄影模式时，快门按钮的单次操作将连续产生两个触发信号。所产生的触发信号触发切换装置，使得拍摄停止的位置自动切换到为拍摄模式预定的位置，并且使摄影光源发射与所选拍摄模式对应的次数。在这种配置中，通过快门的单次操作自动地产生眼底图像的设定次数。因此，可以获得高质量的眼底图像，而不用担心捕获图像的适当时刻将被遗漏。

摘要： Multiple fundus images are obtained and stored in a memory. The images concern a same eye to be examined, but are obtained at different positions relative to the optical axis of the eyeball. An image playback portion repeatedly displays fundus images from the memory, in order at a predetermined time pitch and as obtained from the different positions. This encompasses a stereoscopic range, using display of the images one-by-one.

摘要： An optical apparatus is provided with storage means for storing captured images taken beforehand within a range of directional variability of an optical imaging system. The direction of the optical imaging system is detected and an image obtained in the detected direction is read from the storage means and displayed in place of an image actually being taken by the optical imaging system. When the scene desired to be viewed is not clearly visible or hard to find owing to cloudiness or the like, the user can view a corresponding simulated scene and, based on the simulated scene, can quickly find and view the actual scene. The real or simulated scene can be displayed for a predetermined period of time in response to insertion of a coin.

摘要： The ocular fundus of an eye under examination is stereo-photographed via an ocular fundus photographing optical system with a predetermined parallax (S100). The photographed stereo ocular fundus images are subjected to color separation (S101) when a process of measuring the three-dimensional shape of the ocular fundus of the eye under examination is to be performed using left and right parallax images obtained. A depth information measurement process to derive depth information of a specific ocular fundus region is carried out on the respective stereo ocular fundus images of different wavelengths obtained by the color separation (S103), and a thickness information measurement process is carried out to derive, as thickness information for specific ocular fundus tissue, a difference of depth information obtained respectively from stereo ocular fundus images of different wavelength components in the depth information measurement process (S104). Additionally, a spatial frequency filtering process is carried out for an image of a specific frequency component (S103).

摘要： An illumination light is projected onto a tear film lipid layer on a cornea of an eye to be examined, and the reflected light is received and the tear film lipid layer is imaged. The image of the tear film lipid layer that has been captured is processed, and the initial spread speed H′ of the tear film lipid layer at the time the eyelid has been opened is measured. The image of the tear film lipid layer that has been captured is processed, and the time until the tear film lipid layer is broken up after the eyelid has been opened and a dark area T appears is measured. The appearance time of the dark area is plotted on the Y-axis and the initial spread speed H′(0) of the tear film lipid layer is plotted on the X-axis, and the type of dry eye is classified. In such a configuration, since the type of dry eye can be classified and determined, diagnosis and treatment in accordance with the type of dry eye are made possible.
