Title:
OPHTHALMOLOGICAL OBSERVATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/113459
Kind Code:
A1
Abstract:
Provided is an ophthalmological observation device that makes it possible to determine with high accuracy the positional relationship between an image and a tomographic view. An imaging mask (127) is provided with light-transmitting sections (127c, 127d), at a location roughly conjugate to an imaging device (12), that cause marks identifying the location of the imaging device (12) to appear in taken images. A memory unit (212) stores reference position information (213) based on the positions of the marks (F1, F2) in a reference image (T). The reference position information (213) includes information on the position of a reference center (K0) and a reference line (H0). When a fundus image (Ef′) and a tomographic view are formed, an image processing unit (230) translates the fundus image (Ef′) and tomographic view on the basis of the image center (K), as determined by the positions of the marks (M1, M2) in the fundus image (Ef′), and the reference center (K0). The image processing unit also rotates the fundus image (Ef′) and tomographic view on the basis of the center line (H), as determined by the marks (M1, M2), and the reference line (H0).
