Ophthalmologic apparatus, method of controlling ophthalmologic apparatus, and program

An ophthalmologic apparatus comprising:

• a scan unit configured to repeatedly perform two-dimensional scanning on a fundus of an eye to be inspected with measuring light, the two-dimensional scanning including scanning in a first direction and scanning in a second direction, wherein the second direction is different from the first direction, and wherein a speed of reciprocating scanning in the second direction is lower than that in the first direction;
• an image generation unit configured to generate a two-dimensional image of the fundus based on reflected light of the measuring light from the fundus that is two-dimensionally scanned;
• and
• a control unit configured to control an amount of the measuring light radiated to the fundus in scanning of a return path in the second direction to be smaller than an amount of the measuring light radiated to the fundus in scanning of a forward path in the second direction.

A method of controlling an ophthalmologic apparatus, the method comprising:

• repeatedly performing, by a scan unit, two-dimensional scanning on a fundus of an eye to be inspected with measuring light, the two-dimensional scanning including scanning in a first direction and scanning in a second direction, wherein the second direction is different from the first direction, and wherein a speed of reciprocating scanning in the second direction is lower than that in the first direction;
• generating a two-dimensional image of the fundus based on reflected light of the measuring light from the fundus that is two-dimensionally scanned;
• and
• controlling, in the two-dimensional scanning, an amount of the measuring light that is radiated to the fundus in scanning not being used to generate the two-dimensional image including at least scanning of a return path in the second direction to be smaller than an amount of the measuring light that is radiated to the fundus in scanning being used to generate the two-dimensional image.
