OPHTHALMOLOGIC APPARATUS AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To reduce shift of an acquired image due to delay from when a drive command is issued to a scanner until an actual drive position of the scanner reaches the command position.SOLUTION: An ophthalmologic apparatus includes; optical scanning means for scanning measurement light on a subject's eye; acquisition means for receiving the light reflected from the subject's eye and acquiring a light reception signal; and command means for commanding a drive position of the optical scanning means. The ophthalmologic apparatus further includes: position detection means for detecting a current position of the optical scanning means; and measurement means for measuring a drive delay time from when the command means issues the command until the current position reaches the commanded drive position. The acquisition means starts to acquire the light reception signal at timing based on the drive delay time.
