Abstract: An ophthalmologic apparatus of an embodiment example includes a front image acquiring device, a first search processor, and a second search processor. The front image acquiring device is configured to acquire a front image of a fundus of a subject's eye. The first search processor is configured to search for an interested region corresponding to an interested site of the fundus based on a brightness variation in the front image. The second search processor is configured to search for the interested region by template matching between the front image and a template image in the event that the interested region has not been detected by the first search processor.

Abstract: Provided are an ophthalmologic device and a method of controlling the same capable of accurately and reliably acquiring ocular characteristics of a subject eye. The ophthalmologic device includes: a face supporting unit configured to support a face of an examinee; an anterior ocular segment image acquiring unit configured to repeatedly acquire an anterior ocular segment image of the subject eye of the face supported by the face supporting unit; a pupil image detecting unit configured to detect a pupil image of the subject eye for each anterior ocular segment image based on the anterior ocular segment image repeatedly acquired by the anterior ocular segment image acquiring unit; and a determining unit configured to determine whether or not the face is properly supported by the face supporting unit based on a result of detection of the pupil image for each anterior ocular segment image by the pupil image detecting unit.

Abstract: An ophthalmic information processing apparatus is configured to remove an artifact of an image of a subject's eye obtained using an ophthalmic apparatus. The ophthalmic information processing apparatus includes an identifying unit and a correction unit. The identifying unit is configured to identify a correction region in the image based on a dioptric power of the subject's eye. The correction unit is configured to correct a luminance in the correction region identified by the identifying unit, based on a correction amount corresponding to the dioptric power of the subject's eye.

Abstract: An ophthalmological device of some embodiment examples includes a memory, detecting processor, identifying processor, transforming processor, and composing processor. The memory stores a plurality of angiograms acquired by applying optical coherence tomography to an eye fundus. The detecting processor is configured to detect a feature point from each of the angiograms. The identifying processor is configured to identify a plurality of feature point groups from among a plurality of feature points detected from the angiograms. Each feature point group corresponds to a same site of the eye fundus. The transforming processor is configured to transform at least part of the angiograms based on the feature point groups. The composing processor is configured to compose two or more angiograms of the angiograms at least part of which has been transformed, based on the feature point groups.
