Abstract
An imaging apparatus includes an image sensor sensitive to infrared rays, and a control circuit. The control circuit determines whether the imaging apparatus is mounted on a fundus camera in a state where an image of a fundus of a subject's eye can be captured based on reflected light flux from the fundus, and controls a function of the imaging apparatus depending on the determination.
Claims17
An imaging apparatus that can be removably mounted on an ophthalmologic apparatus, the ophthalmologic apparatus comprising an illumination optical system configured to irradiate a subject's eye with light emitted from a light source through an objective lens, the imaging apparatus comprising:
- an imaging unit sensitive to infrared light;
- and
- a control unit configured to control a function of the imaging apparatus in a case where the imaging apparatus is mounted on the ophthalmologic apparatus in a state where an image of a fundus can be captured with infrared light.
A method of controlling an imaging apparatus that can be removably mounted on an ophthalmologic apparatus and has an imaging unit sensitive to infrared light, the ophthalmologic apparatus comprising an illumination optical system configured to irradiate a subject's eye with light emitted from a light source through an objective lens, the method comprising:
- determining whether the imaging apparatus is mounted on an ophthalmologic apparatus in a state where an image of a fundus of the subject's eye can be captured with infrared light;
- and
- controlling a function of the imaging apparatus depending on the determination.
A program that causes a computer to execute a method of controlling an imaging apparatus that can be removably mounted on an ophthalmologic apparatus and has an imaging unit sensitive to infrared light, the ophthalmologic apparatus comprising an illumination optical system configured to irradiate a subject's eye with light emitted from a light source through an objective lens, the method comprising:
- determining whether the imaging apparatus is mounted on an ophthalmologic apparatus in a state where an image of a fundus of the subject's eye can be captured with infrared light;
- and
- controlling a function of the imaging apparatus depending on the determination.
An ophthalmic system, comprising:
- an ophthalmologic apparatus that comprises an illumination optical system configured to irradiate a subject's eye with light emitted from a light source through an objective lens;
- an imaging apparatus that can be removably mounted on the ophthalmologic apparatus and has an imaging unit sensitive to infrared light;
- and
- a control apparatus that controls the imaging apparatus so that a state disabling predetermined photographing by the imaging apparatus in a case where the imaging apparatus is mounted on the ophthalmologic apparatus in a state where an image of a fundus of a subject's eye can be captured with infrared light.
A fundus camera that can have an imaging apparatus mounted thereon in a removable manner, the apparatus including an imaging unit sensitive to infrared light, the camera comprising:
- a second member that can be disposed at a predetermined position relative to a first member of the imaging apparatus,
- wherein the imaging apparatus is in a state where an image of a fundus of a subject's eye can be captured in a case where the first and second members are disposed at predetermined positions respectively.
An imaging apparatus that can be removably mounted on an ophthalmologic apparatus, comprising:
- an imaging unit sensitive to infrared light;
- and
- a control unit configured to control the imaging apparatus so that a state disabling predetermined photographing is canceled in a case where the imaging apparatus is mounted on the ophthalmologic apparatus in a state where an image of a fundus of a subject's eye can be captured with infrared light.
