发明名称 Ophthalmic Apparatus and Ophthalmic Method
摘要 An ophthalmic apparatus includes a fundus image acquisition unit which acquires a plurality of fundus images acquired by imaging fundus of a subject's eye at different times and at least one fundus image that is fewer than the plurality of fundus images and acquired by imaging fundus of the subject's eye at a different time from those for the plurality of fundus images, a unit which generates a new fundus image by averaging the plurality of fundus images, an extraction unit which extracts a feature region from the generated new fundus image, and a unit which tracks the fundus such that positions of a first polarization tomographic image of the fundus corresponding to the new fundus image and a second polarization tomographic image of the fundus corresponding to the at least one fundus image may be corrected based on the extracted feature region and the at least one fundus image.

主权项 1. An ophthalmic apparatus, comprising: a fundus image acquisition unit configured to acquire a plurality of fundus images acquired by imaging fundus of a subject's eye at different times and at least one fundus image that is fewer than the plurality of fundus images and acquired by imaging fundus of the subject's eye at a different time from those for the plurality of fundus images; a unit configured to generate a new fundus image by averaging the plurality of fundus images; an extraction unit configured to extract a feature region from the generated new fundus image; and a unit configured to track the fundus such that positions of a first polarization tomographic image of the fundus corresponding to the new fundus image and a second polarization tomographic image of the fundus corresponding to the at least one fundus image may be corrected on basis of the extracted feature region and the at least one fundus image.
