Ophthalmic imaging apparatus, control method therefor, and non-transitory computer-readable storage medium

An ophthalmic imaging apparatus, comprising:

• an imaging unit configured to perform imaging to produce a tomographic image of a fundus of an examined eye based on interference light obtained by combining measurement light and reference light in a vitreous body mode or in a choroid mode, wherein the imaging unit sets, in the vitreous body mode, a position in which an optical path length of the measurement light and an optical path length of the reference light match at a vitreous body side of the examined eye, and sets, in the choroid mode, the position at a choroid side of the examined eye;
• a movement unit configured to move the position from the vitreous body side to the choroid side;
• a generation unit configured to generate a fundus image based on a plurality of tomographic images having been produced through imaging performed by the imaging unit in the choroid mode;
• and
• a display control unit configured to display, on a display unit, (a) the tomographic image imaged in the vitreous body mode and (b) the fundus image generated based on the plurality of tomographic images imaged in the choroid mode.

A control method for an ophthalmic imaging apparatus, the control method comprising:

• an imaging step of performing imaging to produce a tomographic image of a fundus of an examined eye based on interference light obtained by combining measurement light and reference light in a vitreous body mode or in a choroid mode, wherein the ophthalmic imaging apparatus sets, in the vitreous body mode, a position in which an optical path length of the measurement light and an optical path length of the reference light match at a vitreous body side of the examined eye, and sets, in the choroid mode, the position at a choroid side of the examined eye;
• a determination step of determining whether aliasing has occurred in the tomographic image imaged in the vitreous body mode;
• a movement step of, when the determination step has determined that the aliasing has occurred, moving the position from the vitreous body side to the choroid side;
• a generation step of generating a fundus image based on a plurality of tomographic images having been produced through imaging performed in the imaging step in the choroid mode;
• and
• a display control step of displaying, on a display unit, (a) the tomographic image imaged in the vitreous body mode and (b) the fundus image generated based on the plurality of tomographic images imaged in the choroid mode.
