Ophthalmologic apparatus and method for controlling the same

An ophthalmologic apparatus comprising:

• an acquisition unit configured to acquire a fundus image of a subject's eye;
• a displacement acquisition unit configured to acquire the displacement of an imaging position between the fundus images acquired by the acquisition unit;
• and
• a display control unit configured to display on a display unit the fundus image acquired by the acquisition unit and a region of interest which is a radial area where a tomogram of the fundus is captured;
• wherein the display control unit performs display control to display the fundus image and the region of interest on the display unit based on the displacement acquired by the displacement acquisition unit so that the region of interest can be positioned in a predetermined position of the fundus image.

An ophthalmologic apparatus comprising:

• an acquisition unit configured to acquire a fundus image of a subject's eye;
• a displacement acquisition unit configured to acquire the displacement of an imaging position between the fundus images acquired by the acquisition unit;
• and
• a display control unit configured to display on a display unit the fundus image acquired by the acquisition unit and a region of interest which is a circular area where a tomogram of the fundus is captured;
• wherein the display control unit performs display control to display the fundus image and the region of interest on the display unit based on the displacement acquired by the displacement acquisition unit so that the region of interest can be positioned in a predetermined position of the fundus image.

• and
• a display control unit configured to display on a display unit the fundus image acquired by the acquisition unit and a region of interest which is an area where a tomogram of the fundus is captured;
• wherein the display control unit moves the region of interest on the display unit based on the displacement acquired by the displacement acquisition unit so that the region of interest can be positioned in a predetermined position of the fundus image, and changes a display form for the region of interest if the region of interest is positioned outside the area where the tomogram can be captured.

A method for controlling an ophthalmologic apparatus including an acquisition unit, a displacement acquisition unit, and a display control unit, the method comprising:

• acquiring a fundus image of a subject's eye with the acquisition unit;
• acquiring the displacement of an imaging position between the fundus images acquired with the displacement acquisition unit;
• and
• controlling display of the acquired fundus image and a region of interest which is an area where a tomogram of the fundus is captured on a display unit, with the display control unit;
• wherein in carrying out the display control, the display control unit performs control to display the fundus image and the region of interest on the display unit based on the acquired displacement so that the region of interest is positioned at a predetermined position of the fundus image, and stops the display control based on the position of the subject's eye.
