Abstract
Official abstract text for this publication.
An ophthalmic apparatus comprising: an acquisition unit configured to acquire a first fundus image of an eye and a second fundus image of the eye; a first generation unit configured to generate, by performing processing of enhancing contrast of a first characteristic region of a part of the first fundus image, an image which corresponds to the first characteristic region; a second generation unit configured to generate, by performing processing of enhancing contrast of a second characteristic region of a part of the second fundus image which corresponds to the first characteristic region, an image which corresponds to the second characteristic region; and a correction unit configured to correct an acquisition position of a tomographic image of the eye based on a positional displacement between the images which respectively correspond to the first and second characteristic regions.
