FUNDUS OBSERVATION APPARATUS

An apparatus for observing a fundus of an eye of an examinee has an observation optical system having an image-pickup element which obtains a time-series fundus image, a display part which displays the obtained fundus image on its monitor as a moving image, a determination part which determines a standard fundus image based on the displayed image, a memory part which stores the determined image, a calculation part which digitizes the image based on a threshold luminance level to obtain a digitized image thereof, digitizes a present fundus image obtained after the determination of the standard image based on the threshold luminance level to obtain a digitized image thereof and compares the obtained digitized images two-dimensionally to obtain their positional difference, and a display control part for correcting a display position of the present fundus image based on the obtained positional difference to display the corrected image on the monitor.
