Ophthalmologic photographing apparatus and camera for use in ophthalmologic photographing

An ophthalmologic photographing apparatus comprising a fundus camera body including an illumination optical system configured to illuminate a subject's eye and a photographing optical system configured to photograph the subject's eye illuminated by the illumination optical system with one of infrared light and visible light, and a camera detachable from the fundus camera body and including an image sensor with a light-receiving surface to receive return light from the subject's eye through the photographing optical system and a display unit, the ophthalmologic photographing apparatus comprising:

• a first display control unit configured to cause the display unit to display an image of the subject's eye formed on the light-receiving surface in monochrome based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the infrared light;
• and
• a second display control unit configured to cause the display unit to display an image of the subject's eye formed on the light-receiving surface in color based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the visible light.

A camera which is detachable from an ophthalmologic photographing apparatus including an illumination optical system configured to illuminate a subject's eye with illumination light, the camera comprising:

• an image sensor configured to form an image from return light from the subject's eye through a photographing optical system in the ophthalmologic photographing apparatus;
• and
• a reception unit configured to receive, from the ophthalmologic photographing apparatus, either a still image photographing signal obtained by forming an image on the image sensor from visible light from the subject's eye or a moving image observation signal obtained by forming an image on the image sensor from infrared light from the subject's eye.

An ophthalmologic photographing method for an ophthalmologic photographing apparatus comprising a fundus camera body including an illumination optical system configured to illuminate a subject's eye and a photographing optical system configured to photograph the subject's eye illuminated by the illumination optical system with one of infrared light and visible light, and a camera detachable from the fundus camera body and including an image sensor with a light-receiving surface to receive return light from the subject's eye through the photographing optical system and a display unit, the ophthalmologic photographing method comprising:

• a first display control step to cause the display unit to display an image of the subject's eye formed on the light-receiving surface in monochrome based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the infrared light;
• and
• a second display control step configured to cause the display unit to display an image of the subject's eye formed on the light-receiving surface in color based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the visible light.

A method of controlling an ophthalmologic photographing apparatus including an illumination optical system configured to illuminate a subject's eye and a photographing optical system configured to photograph the subject's eye illuminated by the illumination optical system with one of infrared light and visible light, the method comprising:

• causing a display unit to display an image of the subject's eye formed on a light-receiving surface of an image sensor with the light-receiving surface to receive return light from the subject's eye through the photographing optical system based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the infrared light;
• and
• causing the display unit to display an auto-fluorescence photographed image of the subject's eye formed on the light-receiving surface based on an output signal from the image sensor in a case where the subject's eye is auto-fluorescence photographed by the illumination optical system illuminating the subject's eye with the visible light.

A camera attachable to a main body of a fundus camera including an illumination optical system configured to illuminate a subject's eye and a photographing optical system configured to photograph the subject's eye illuminated by the illumination optical system with one of infrared light and visible light, the camera comprising:

• an image sensor with a light-receiving surface to receive return light from the subject's eye through the photographing optical system;
• a display unit configured to display an image of the subject's eye formed on the light-receiving surface based on an output signal from the image sensor in a case where the illumination optical system illuminates the subject's eye with the infrared light and to display an auto-fluorescence photographed image of the subject's eye formed on the light-receiving surface based on an output signal from the image sensor in a case where the subject's eye is auto-fluorescence photographed by the illumination optical system illuminating the subject's eye with the visible light.
