An optical adapter for connecting between a beam splitter of a surgical microscope or an ophthalmic slit lamp microscope and a digital camera equipment including mobile phones, tablet computers, cameras, video cameras with image capturing function is provided. The optical adapter includes a lens group located on an optical path and an optical image rotating lens group for adjusting a direction of an optical image on a photosensitive unit of the digital camera equipment. The optical image rotating lens group is configured to be either independently rotatable around optical axis or be set fixedly. Embodiments of the present invention provide a system and method for real-time adjustment of the direction of an optical image on the photosensitive unit of a digital camera equipment, where regardless of the position of the digital camera a satisfactory direction of the optical image can be obtained with a simple user friendly and convenient structure.

In the ophthalmic imaging apparatus of an aspect example, the first image collecting unit collects a series of Scheimpflug images by performing scanning of a three dimensional region of a subject's eye with slit light. The second image collecting unit collects a series of time series images by performing repetitive photography of the subject's eye in parallel with the scanning of the three dimensional region performed by the first image collecting unit. The first image analyzing unit analyzes the series of time series images to determine time series shifts of the slit light during the scanning of the three dimensional region performed by the first image collecting unit. The image interpolating unit performs interpolation of the series of Scheimpflug images based on the time series shifts of the slit light determined by the first image analyzing unit.

A slit-lamp microscope includes a base plate defining an x-axis and a z-axis. The microscope includes a movable base member slidably disposed on the base plate. The microscope includes a computer that generates first and second control signals to induce first and second movement devices, respectively, to move the movable base member in response to a first x-axis command and a first z-axis command, respectively, in first and second remote control messages, respectively. The computer generates a third control signal to induce the digital camera of the microscope assembly to generate a digital image from the light received from the subjects eye in response to the photograph command in a third remote control message.

A close-up imaging device that generates slit light on the basis of light-source light emitted from a light source built into a mobile communication terminal device. The close-up imaging device is mounted onto the mobile communication terminal device, and a moving image of the tissue to be observed of the examined eye is captured by a camera module built into the mobile communication terminal device. Then, in a diagnosis support server device, a diagnosable frame image included in the captured moving image is extracted, at least one of a heath state of the examined eye and any one or more of a distance, an angle, and an area in some tissue of the examined eye is estimated on the basis of the diagnosable frame image extracted, and diagnosis support information is generated and distributed to the corresponding mobile communication terminal device.
