Title:
OPHTHALMOLOGIC PHOTOGRAPHING DEVICE
Document Type and Number:
Japanese Patent JP2021072979
Kind Code:
A
Abstract:
To provide an ophthalmologic photographing device that can acquire an OCT image with high accuracy even if movement of a subject's eye occurs.SOLUTION: A data collection unit of an ophthalmologic photographing device according to an embodiment collects data by applying three-dimensional scans to a subject's eye. A control unit controls the data collection unit so as to perform scans sequentially with respect to a plurality of unit scan areas set by previously dividing a scan area to which the three-dimensional scans are applied. The data collection unit applies the scans sequentially by a predetermined number of times with respect to each of a plurality of scan lines included in one unit scan area under control of the control unit. An abnormality detection unit detects occurrence of displacement of the subject's eye on the basis of data collected by the scans for the one unit scan area.SELECTED DRAWING: Figure 5
