Handwriting Extraction
Application
This application identifies and extracts text and
diagrams drawn on a whiteboard or blackboard in real-
time, and renders them so that they appear in front of the
speaker.
Note
The Handwriting Extraction option function must be
enabled before configuring or running the Handwriting
Extraction application. Activate the corresponding pre-
installed license, or purchase and install a license.

Preparation before setup

1
Connect a camera to the HDMI IN 1
connector, and connect the device to which
you want to output the extracted image to
the HDMI OUT 1 connector.
2
Turn on the camera and peripheral devices.
Notes
• Adjust the position and field of view of the camera
connected to the HDMI IN 1 connector so that the
blackboard or whiteboard fits within the field of view
of the camera.
• Adjust the focus of the remote camera connected to
the HDMI IN 1 connector manually so that the whole
view of the blackboard or whiteboard to extract is in
focus. Adjust the white balance and exposure
manually according to the usage environment.
• When the remote camera configured in [Input/Output]
(page 11) is connected to the HDMI IN 1 connector
and configured correctly, the white balance and
exposure of the camera may be adjusted by the unit
according to the usage environment while the
application is running.
Configuring the Handwriting
Extraction application
1
Select [Handwriting Extraction] from
[Applications].

Click the [Setup] button.
The setup screen appears. A preview of the image
from the camera connected to the HDMI IN 1
connector is displayed on the screen.
Note
If the camera image is not displayed, there may be a
problem with the camera connection or settings.
Check the connection and settings again.
3
Configure the following settings.
Extraction range
Move the four blue circles displayed on the preview
screen to select the target area (blackboard or
whiteboard) to extract. Take care to not select the
parts of the blackboard or whiteboard, such as the
frame, not related to the writing on the board.
Board color
Select the type of board for extraction.
[White]: White surface used for writing, such as a
whiteboard
[Black]: Dark surface used for writing, such as a
blackboard
Text color
Select how to display the extraction result for non-
white text written on a blackboard.
This setting is enabled only when the board color is
set to [Black].
[Color]: White text on a blackboard is output as
black text, and non-white text on a blackboard is
output in color in the extraction result.
[Monochrome]: White text and non-white text are
both output as black text in the extraction result.
Overlap mode
Select whether to superimpose an image of the
person in the output over the writing when
extracting the handwriting.
You can change the overlap mode using the [Show
Person] checkbox. When the checkbox is cleared,
only the handwriting is extracted.
When [Show Person] is checked: Superimpose an
image of the person writing at the same time
when extracting the handwriting.
