A method of processing ophthalmic data of some embodiment examples includes preparing a data set acquired by applying optical scanning of a two-dimensional pattern to a subject's eye. The two-dimensional pattern of the optical scanning includes a series of cycles that intersects each other. The method further includes generating position history data based on the data set. The position history data represents a temporal change in a position of the subject's eye.

Method of processing ophthalmic data, ophthalmic data processing apparatus, and ophthalmic examination apparatus

In the ophthalmic imaging apparatus of an aspect example, the first image collecting unit collects a series of Scheimpflug images by performing scanning of a three dimensional region of a subject's eye with slit light. The second image collecting unit collects a series of time series images by performing repetitive photography of the subject's eye in parallel with the scanning of the three dimensional region performed by the first image collecting unit. The first image analyzing unit analyzes the series of time series images to determine time series shifts of the slit light during the scanning of the three dimensional region performed by the first image collecting unit. The image interpolating unit performs interpolation of the series of Scheimpflug images based on the time series shifts of the slit light determined by the first image analyzing unit.
