摘要:
A plurality of sensed images of an eye to be examined and a plurality of time information at image sensing are acquired. A plurality of information correlate with image, each of which including at least the time information, at the image sensing are acquired. A group of the images of the eye to be examined and a group of the information correlate with image sensing are correlated with each other based on the time information at the image sensing and the time information included in the information correlate with image sensing, thereby recording an image of the eye to be examined and information correlate with image sensing which are correlated with each other.

摘要:
When the fundus camera is positioned on the same side as the subject's eye relative to an appropriate position (front-focus state), the positioning index light source turned on in blue produces most-focused positioning index images. The positioning index light sources become more blurred in order of green and red. When the camera is positioned on the opposite side of the subject's eye relative to the appropriate position (rear-focus state), the positioning index light source turned on in red produces most-focused images. The positioning index light sources become more blurred in order of green and blue. Based on a degree of the blur of the individual positioning index images in red, green, and blue reflected by the cornea of the subject's eye, the calculation unit calculates whether to move the camera body closer to or farther away from the subject's eye and allows the display unit to display the information.

An ophthalmologic imaging apparatus that captures a fundus image of a subject's eye includes a first extraction unit configured to extract, from a first fundus image photographed with a first light quantity, an image of a first area having intensity not less than predetermined intensity and an image of a second area other than the first area, a second extraction unit configured to extract an image of an area corresponding to the first area from a second fundus image photographed with a second light quantity based on the light quantity of the first area, a third extraction unit configured to extract an image of an area corresponding to the second area from a third fundus image photographed with a third light quantity based on the light quantity of the second area, and an image combining unit configured to combine the images extracted by the second and the third extraction units.
摘要:
Provided is an ophthalmologic image taking apparatus with which an image of the eye to be examined can be taken with an appropriate light intensity and at an appropriate gain. In the case where an observation of an eye to be examined is conducted when it is detected that an image taking switch is turned on, an image taking light source emits light after a lapse of a predetermined time. The predetermined time is a time required to completely switch a gain from a gain obtained by AGC to a fixed gain and a time which is not influenced by blinking of the eye to be examined.

There is provided an ophthalmologic apparatus. According to the ophthalmologic apparatus, irradiating times of tracking light and measuring light are measured for each measured part and then an energy integrated value Ex is calculated. Further, MPE is calculated based on a period from the time of irradiation to the current time and the proportion of the integrated value Ex to the MPE is calculated and displayed. When the proportion of the integrated value Ex to the MPE is 100% or more, tracking light irradiation is stopped. When the proportion of the integrated value Ex to the MPE has not reached 100%, measurement using the measuring light is conducted while the proportion of the integrated value Ex to the MPE is obtained.
摘要:
An ophthalmic imaging apparatus which obtains a tomographic image of an eye to be examined based on light obtained by combining return light from the eye irradiated with measurement light with reference light corresponding to the measurement light, the apparatus comprising: a scanning unit configured to scan the measurement light on the eye; and a control unit configured to control the number of times of scanning by the scanning unit in accordance with a scanning position of the scanning unit on the eye.
摘要:
A fundus camera includes an irradiation unit including a plurality of LED elements and a fluorescent material that emits light by being excited by light emitted from the LED elements and configured to emit light that is generated by combining light emitted from the LED elements and excitation light from the fluorescent material, an illumination optical system configured to irradiate an eye fundus of a subject's eye with the light emitted by the illumination unit, an observation unit configured to form an eye fundus image by receiving light, which is emitted from the illumination unit and reflected from the eye fundus, and an imaging unit configured to pick up the eye fundus image formed by the observation unit.
摘要:
When an anterior segment photographing mode is selected, ease of operation by an inspector is improved. An ophthalmologic apparatus includes an area changing unit for changing a movement area of an optical unit including an optical path of measuring light, when an anterior segment photographing mode for photographing an anterior segment of an eye to be inspected is selected, to be different from a movement area when a mode other than the anterior segment photographing mode is selected.
