摘要： A fundus photography device includes: an OCT optical system configured to detect interference between a measurement light from a fundus of a subject's eye and a reference light from a reference optical path; a fundus photography optical system configured to detect a reflected light from the fundus; a controller configured to generate a tomographic image of the fundus and a first front image of the fundus based on an output signal from the OCT optical system, and generate a second front image of the fundus based on an output signal from the fundus photography optical system. The controller is configured to cause simultaneous display of the first front image and the second front image in different display regions on a monitor.

摘要： An ophthalmological image processing apparatus acquires a plurality of images of a subject eye photographed in a scanning-type imaging optical system, sets any one of the plurality of images as a template, sets corresponding points or corresponding regions between an image of the subject eye and the template at a plurality of positions of each of the image of the subject eye and the template, calculates a movement amount of each of the corresponding points or each of the corresponding regions, and corrects a distortion of the image of the subject eye with respect to the template based on the movement amount of each of the corresponding points or each of the corresponding regions.
