Abstract: An ophthalmological observation device (1) according to an exemplary embodiment comprises moving image generation units (30, 40), an analysis unit (211), and a display control unit (200). The moving image generation units image a subject eye having an artificial object inserted therein to generate a moving image. The analysis unit analyzes a still image included in the moving image generated by the moving image generation units, and specifies a first site image corresponding to a predetermined site of the subject eye and a second site image corresponding to a predetermined site of the artificial object. The display control unit causes a display device (3) to display the moving image generated by the moving image generation units, first position information indicating the position of the first site image specified by the analysis unit, and second position information indicating the position of the second site image specified by the analysis unit.

Abstract: An ophthalmological observation device (1) according to an exemplary embodiment of the present invention comprises a moving image generation unit (30, 40), an analysis unit (211), a target location determination unit (212), and a display control unit (200). The moving image generation unit images a subject eye to generate a moving image. The analysis unit analyzes a still image, which is included in the moving image generated by the moving image generation unit, so as to detect an image of a given site in the subject eye. The target location determination unit determines a target location for a predetermined treatment at least on the basis of the image of the given site which has been detected by the analysis unit. The display control unit displays, on a display device (3), the moving image which has been generated by the moving image generation unit and target location information which indicates the target location determined by the target location determination unit.

Abstract: An ophthalmologic observation device (1) according to an exemplary embodiment comprises a microscope (10), processors (203, 211), and a display control unit (201). The microscope includes a pair of imaging systems and a pair of pieces of video data of a to-be-inspected eye. The processor executes first processing so that a predetermined parameter of the pair of pieces of video data satisfies a first condition. The first processing includes at least one among control of the microscope and image processing on at least one of the pair of pieces of video data. The display control unit causes a display device (3) to display a pair of images on the basis of the pair of pieces of video data obtained through the first processing.

Abstract: An ophthalmological observation device (1) according to an exemplary embodiment comprises an illumination system (30), an imaging system (40), and a focus processing unit (200, 210). The illumination system comprises a light source (32a) that emits illumination light and an indicator member (35) provided with a plurality of indicators (36a, 36b), and projects the illumination light on a subject eye (E) via the indicator member. The imaging system comprises an imaging element (62) and captures an image of the subject eye. The focus processing unit detects a plurality of indicator images from the image captured by the imaging system, and performs focus control on the imaging system on the basis of the plurality of indicator images detected.

Abstract: This ophthalmic device includes an illumination optical system, an optical scanner, an imaging optical system, a control unit, and an image forming unit. The illumination optical system generates slit-shaped illumination light. The optical scanner deflects and guides the illumination light to the fundus of an eye being examined. The imaging optical system guides return light of the illumination light from the fundus to an image sensor. The control unit controls the optical scanner. The image forming unit forms an image of the fundus on the basis of a light reception result captured in an imaging object region of a light-receiving surface of the image sensor. The image sensor is configured to capture the light reception result by a rolling shutter system in an opening region of the light-receiving surface that corresponds to a region of the fundus that is illuminated by the illumination light, moved in a predetermined scanning direction by the optical scanner. The control unit controls the optical scanner so that the times of irradiation by return light on a plurality of light-receiving elements in the imaging object region are substantially equal.

Abstract: This ophthalmic device includes a light source, an illumination optical system, an optical scanner, an imaging optical system, and a control unit. The illumination optical system generates slit-shaped illumination light using light from the light source. The optical scanner deflects and guides the illumination light to the fundus of an eye being examined. The imaging optical system guides return light of the illumination light from the fundus to an image sensor that takes in, by means of a rolling shutter method, a light reception result in a region of a light receiving surface corresponding to a region in the fundus illuminated by the illumination light, which is moved by the optical scanner. The control unit controls the angle at which the illumination light is deflected by the optical scanner. The optical scanner outputs a scanner position signal corresponding to the angle at which the illumination light is deflected. The image sensor starts to take in the light reception result of the return light in synchronization with the scanner position signal.
