Patent ID: 7905597

Claim:
A fundus observation device comprising: an image forming part comprising a first image forming part and a second image forming part, the first image forming part forming a 2-dimensional surface image of fundus oculi of an eye through optical processing, the second image forming part comprising one or more galvanometer-mirrors to guide light to the fundus oculi by reflection so that the second image forming part optically scans a surface region of the fundus oculi corresponding to at least a part of the 2-dimensional surface image to form a tomographic image of the fundus oculi to form a 3-dimensional image; a controller configured to change an arrangement of the galvanometer-mirror to control scanning of the surface region of the fundus; and a storage configured to store the arrangement of the galvanometer-mirror as control information, when forming one of the 2-dimensional surface image and the 3-dimensional image is previously completed; and an instruction part to instruct forming the image of the eye to be examined, wherein the controller, at the time of instruction from the instruction part, is adapted to set the arrangement of the galvanometer-mirror to form a new one of the 2-dimensional surface image and the 3-dimensional image as indicated by the control information stored in the memory from the previously-completed image formation such that the control information is maintained over time from one image formation to the next image formation.
