In order to solve problems that it takes time to take an image due to scanning and that measurement of a movement of an eyeball becomes difficult or less accurate with a lapse of time, which are inherent in a scanning-type fundus image photographing apparatus, there is provided a control method for an ophthalmologic apparatus, including: acquiring a fundus image by scanning a photographing area of a fundus with measuring light; extracting a characteristic point from the acquired fundus image; setting, in the photographing area, a partial area containing the characteristic point; acquiring an image of the partial area by scanning the partial area with the measuring light; and detecting a movement of the fundus by executing template matching based on the characteristic point and the image of the partial area.
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
