1. Auto Binary Image Adjustment for Pupil Detection
It allows you to adjust the binary image level of Pupil and Purukinje automatically. If you
set “AUTO”, the binary image adjustment automatically starts when you enter the calibration
mode.
1) In order to set auto binary image adjustment, enter Menu and go to:
Menu > User > Pupil THR:
・AUTO ：Binary image adjustment automatically starts when you enter the
calibration mode, then goes back to the calibration mode upon
completion of the auto binary image adjustment.
・MANUAL (default)：Binary image adjustment is performed manually.
2) When the auto binary image adjustment is completed, a message of “finish” is displayed. If the
auto binary image adjustment is failed, a message of “failure” is displayed. In the later case,
adjust the binary image level of Pupil and Purukinje manually as per 2.5.2.
Note: When you push the FUNCTION key in eye mark mode, the binary image adjustment
automatically start regardless of above Pupil THR setting.

1. Calibration
1) Push the CAL key to go
calibration mode. Nine CAL marks
appear on display (in standard
calibration mode).
CAL mark

EMR-9 Quick Start Guide
__________________________________________________________________________________________________________________________
18 (00175)D
2) Point out a position where the CAL mark
appears on the view image using a laser pointer
or a something stick, such as a pen.
Tips:
9It is easier to calibrate on a wall or a fixed
plane.
9If a laser point may not be visible on the
display, use the stick to point out the CAL
mark.
3) When the subject see the pointed
CAL mark (calibration target point),
push the CUE key (or the Cue
switch). Then the calibration target
point moves to next CAL mark.
4) Repeat seeing the pointed CAL mark and
pushing the CUE key until end of calibration
(9 calibration points).
Upon completion of the calibration, an eye mark
appears on the view image.
Remarks:
If the subject fails to see the CAL mark, push the
FUNCTION key to go back the previous
CAL mark.
If the CAL mark doesn’t move even push the
CUE key, the Pupil and Purkinje images
may not be detected properly. Please cancel the
calibration mode (push the CAL key again)
and readjust binary image level as per 2.5).

2. Calibration Result Check
In case of the 9-point calibration, you can check if the calibration is OK or NG, as
follows. If the lines are on all of 9 CAL marks, the calibration went well. On the other hand, if
the lines are not on or are away from one/some of 9 CAL marks, the calibration was NG.
OK ＮＧ
1) Push the Result Key. The 9 CAL marks and lines appear to
show the result of calibration.
2) You can switch the calibration result of the left eye and the right eye
by pushing the LEFT or RIGHT keys.
3) Push the Result Key again to go back the view image (eye
mark mode).

1. Eye Mark Mode
Immediately after the calibration, the eye mark (the gazing point of the subject) appears on
the view image. This state is called as Eye Mark mode (but the data recording is not made in this
mode). In the Eye Mark mode, you can display eye marks (a left, a right and/or a compensated
eye mark(s)), trajectory of eye mark, real time fixation points.
2. Recording
Then (in the Eye Mark Mode), push the REC Key to start the recording. The data is
recorded on the SD card.
Note:
You can record the eye marks which are superimposed on the view image. However, there
is a time rag up to 3/29.97sec between the eye marks and the view image.
You cannot record the trajectory of the eye marks and the fixation points superimposed on
the view image to the SD card. But you can display those on view image using optional
EMR-dFactory software.
1) Scene Number Setting
You can change the scene
number by the UP or DOWN
keys.
2) Recording
Push the REC key to start the recording. The data is recorded
on the SD card.
During the recording, an access lamp of SD indicator LED flashes.
During the recording, the trajectory or fixation points are not
displayed.
Remarks: During the recording, the recording is stopped if you push
either [CAL] or [RESULT] or [OFFSET] or [MENU] or [FILE] key.
