Abstract
An ophthalmological device of some embodiment examples includes a memory, detecting processor, identifying processor, transforming processor, and composing processor. The memory stores a plurality of angiograms acquired by applying optical coherence tomography to an eye fundus. The detecting processor is configured to detect a feature point from each of the angiograms. The identifying processor is configured to identify a plurality of feature point groups from among a plurality of feature points detected from the angiograms. Each feature point group corresponds to a same site of the eye fundus. The transforming processor is configured to transform at least part of the angiograms based on the feature point groups. The composing processor is configured to compose two or more angiograms of the angiograms at least part of which has been transformed, based on the feature point groups.
