摘要： An ophthalmologic photographing apparatus includes: a photographing optical system including an optical scanner for scanning an examinee's eye with measurement light and a detector for detecting a coherent state of reflected light of the measurement light from the examinee's eye and reference light, the photographing optical system being configured to capture a tomographic image of the examinee's eye in response to an output signal from the detector; a reference data setting unit for setting a photographing condition of a previously acquired captured image as reference data for a follow-up; an image capture data setting unit for setting the reference data set by the reference data setting unit as image capture data for the follow-up; and a tomographic image acquisition controller for acquiring a tomographic image of the examinee's eye by controlling the photographing optical system based on the reference data set as the image capture data.

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.
