Abstract: An information processing apparatus according to the present disclosure includes a transformation unit configured to transform a first region and a second region in a fundus image so that an angle formed between a first straight line and a second straight line approaches 180 degrees, the first and second regions being defined by the first straight line and the second straight line, the second region being larger than the first region, the first straight line passing through a first feature portion related to a macula in the fundus image and being located on a temporal side, the second straight line passing through the first feature portion and a second feature portion related to an optic disc in the fundus image and being located on a nasal side.

Abstract: One of information processing apparatuses according to the technique disclosed herein includes an examination unit, a storage unit, and a control unit. The examination unit is configured to examine an eye of an examinee. The storage unit is configured to store a plurality of examination protocols, each of the plurality of examination protocols including a plurality of examinations. The control unit is configured to control a display unit such that information that represents a plurality of examinations included in each of at least two examination protocols among the plurality of examination protocols stored is displayed on a protocol-by-protocol basis for the at least two examination protocols, and is configured to control the examination unit in accordance with one examination protocol selected according to an instruction given from an examiner from among the at least two examination protocols.

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.
