Abstract

An ophthalmologic information processing apparatus according to the embodiments include a generator, an extractor, and a phase correction unit. The generator is configured to generate a phase difference profile by performing averaging processing in a depth direction on phase differences obtained by calculating for each depth position of A-lines between two adjacent B-frames of complex OCT data of a subject's eye. The extractor is configured to a phase drift from the phase difference profile generated by the generator. The phase correction unit is configured to correct a phase of first complex OCT data of any one of the two B-frames based on the phase drift extracted by the extractor.
