1. An ophthalmological information processing apparatus, comprising:
an acquisition unit including at least one lens and configured to acquire a front image depicting a predetermined site of a subject's eye in multiple gradations and an optical coherence tomography (OCT) image of the subject's eye; and
processing circuitry configured as an image correcting unit configured to correct a pixel value in a region including a first position of the predetermined site in the OCT image based on a pixel value at a second position corresponding to the first position in the front image, wherein
the processing circuitry is further configured as a shape correcting unit configured to correct a shape of the predetermined site so as to follow a traveling direction of measurement light for acquiring the OCT image to generate a correction OCT image,
the image correcting unit is configured to correct the pixel value in the region in the correction OCT image,
the acquisition unit is further configured to acquire the OCT image using the measurement light deflected around a scan center position on the subject's eye, and
the shape correcting unit is further configured to interpolate pixels between A-scan images adjacent to each other according to a depth position in the A-scan image to generate the correction OCT image.
