ABSTRACT:
In an eye fundus examination apparatus such as an eye fundus blood flowmeter, the display on a monitor is changed depending on the detection stage of the eye fundus examination apparatus. When measurement is started, an eye fundus image is zoomed to allow an easy check on the measurement state of the eye fundus. When the measurement is completed, the eye fundus image is restored to its initial size. This makes it possible to easily observe a measurement region during measurement and facilitate observation of measurement data after the measurement. In addition, when an eye fundus image is to be zoomed, a measurement region can be reliably observed by positioning the measurement position in the center of the monitor.
