Abstract: An ophthalmologic photographing apparatus includes a determination unit configured to determine, using the detected information, whether or not an imaging area for imaging an eye is beyond an edge of a predetermined range of movement of the eye to be examined, and a tracking control unit configured to track the imaging area using the detected information, in a case where an imaging mode different from a follow-up imaging mode is selected and the imaging area is determined not to be beyond the edge, to not track the imaging area, in a case where an imaging mode different from the follow-up imaging mode is selected and the imaging area is determined to be beyond the edge, and to track, using the detected information, the imaging area without making the determination by the determination unit, in a case where the follow-up imaging mode is selected.

Abstract: For each of a plurality of second images other than a first image in an image group having a plurality of images, a feature point pair is generated by associating a second feature point of the second image with a first feature point of the first image based on a feature amount of the second feature point. A feature point pair is detected from the generated feature point pairs, where a position of the second feature point in the detected feature point pair is located within a predetermined region. A region including first feature points of the first image is extracted, where in the extracted region, detection counts of the feature point pairs exceed a predetermined threshold.
