GLOSSARY
To assist in use of this manual, the following glossary is provided. Familiarize yourself with the defini-
tions of these words.
 Alignment
Indicates moving the image capturing unit to the optimum position for image capture. The
alignment is performed twice: one in the anterior eye observation screen and the other in the
fundus observation screen.
Anterior eye observation screen: Rough alignment is performed using the electronic working
dot and the working distance indicator.
Fundus observation screen: Fine adjustment is performed using the electronic working dot
and the optical working dot.

Auto focus
Adjusts the focus automatically on the fundus when the anterior eye observation screen is
changed to the fundus observation screen.
 Auto shot
The auto shot is used to perform the sequence of the automatic alignment, auto focus, and
fundus image capture almost automatically only by performing an approximate alignment to
the anterior eye of the patient. The auto shot enables easy fundus image capture by inexpe-
rienced operators.
There are two auto shot types: “With the blink detector” and “Without the blink detector”
When using the auto shot with the blink detector, automatic image capture is started after
the auto tracking and auto focus are completed and the patient’s blink is detected.
When using the auto shot without the blink detector, automatic image capture is started
immediately after the auto tracking and auto focus are completed.
Depending on the condition of the patient’s eye, automatic image capture may be disabled
or captured images may become obscured by blinking.
 Auto tracking function
Adjusts the up, down, left, right, forward, and backward positions of the image capturing unit
automatically to the patient’s eye by detecting eight cornea-reflected spots of infrared LEDs.
 Electronic working dot
Used to perform alignment to the anterior eye and fundus.
It is an illumination spot displayed in the center of the eight infrared LEDs reflected from the
cornea when they are detected. When they are adjusted to the center of the target mark, the
image capturing unit is in the optimum position both vertically and horizontally for image cap-
ture in the anterior eye or fundus observation screen.
