Title:
OPHTHALMOLOGICAL DEVICE, OPHTHALMOLOGICAL IMAGE PROCESSING METHOD, PROGRAM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2018/235471
Kind Code:
A1
Abstract:
An ophthalmological device in an embodiment comprises a storage unit, a detection unit, a specification unit, a deformation unit and a compositing unit. The storage unit stores a plurality of angiograms obtained by applying optical coherence tomography to the fundus of an eye being examined. The detection unit detects feature points from each of the plurality of angiograms. The specification unit specifies a plurality of feature points groups, each of said groups corresponding to the same site on the fundus, from the plurality of feature points detected by the detection unit from among the plurality of angiograms. The deformation unit deforms at least some of the plurality of angiograms on the basis of the plurality of feature point groups specified by the specification unit. The compositing unit combines two or more angiograms from among the plurality of angiograms, at least some of which were deformed by the deformation unit, on the basis of the plurality of feature point groups.
