Abstract
An ophthalmologic apparatus includes an imaging unit for imaging the fundus image of a subject's eye, a displacement acquisition unit for acquiring the displacement of an imaging position by the imaging unit between fundus images captured by the imaging unit, and a display control unit for displaying the fundus image captured by the imaging unit and a region of interest on the display unit so that the region of interest is positioned at a predetermined position of the fundus image based on the displacement acquired by the displacement acquisition unit and displaying the region of interest on the display unit by changing a size of the region of interest according to an range where the fundus image is captured.
Claims18
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 a 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 an area where a tomogram of the fundus is taken;
- wherein the display control unit displays 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 is positioned at a predetermined position of the fundus image, and displays the region of interest on the display unit by changing a size of the region of interest according to a range where the fundus image is captured.

An ophthalmologic apparatus comprising:
- an acquisition unit configured to acquire a fundus image acquired based on interference light between return light from a subject's eye and reference light;
- 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 an area where a tomogram of the fundus is taken;

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 the fundus image acquired by the displacement acquisition unit and a region of interest which is an area where a tomogram of the fundus is taken on a display unit so that the region of interest is positioned in a predetermined position of the fundus image based on the displacement acquired by the displacement acquisition unit;
- wherein the display control unit displays a common portion between the fundus images on the display unit in such a way as to reduce the displacement based on the displacement acquired by the displacement acquisition unit to display the region of interest in the predetermined position on the fundus image, and enlarges and displays the region of interest and the common portion.
