Document cameras
A document camera is a video camera designed to display documents and 3-D objects on a
display device, for example a computer monitor or data projector. The power of a document
camera lies in its flexibility - you can point, mark, zoom in and out and view objects from different
angles by moving them. If you want to display anything other than a computer-generated image
then a document camera is the tool to use.
A document camera can capture and project any object placed in its field of vision. Examples of
objects that can be projected include:
Pieces of paper
Pages in a book
Three-dimensional objects
35mm slides
Large items or a person in a room.
Turning on a document camera
Turning on a document camera and displaying
documents or objects via the installed data
projector is a two-step process:
1. Turn on the document camera.
The power switch is located in the upper
right-hand corner of the document camera.
Use this switch to turn on the document
2. Turn on the data projector.
The data projector is controlled by either a
touch panel control system or a hand held
remote control.

Using the document camera controls
The following controls are available from the front panel of the document camera:
Pressing the Pause button captures & freezes the image that is currently being
displayed. Pressing the pause button again un-freezes the image and returns the
document camera to normal operation.
Pressing the Open or Close iris buttons adjusts the brightness of the image.
Pressing the Auto/Manual button toggles between automatic and manual iris
adjustment. The default iris setting is automatic.
Pressing the White Balance button allows you to adjust the colour balance of the
image being displayed
Pressing the Image Rotation button rotates the displayed image 90° counter
clockwise each time the button is pressed.
Pressing the Lamp button cycles between the upper lamp on, base lamp on and
lamp off.
Must be set to Main output. The other two settings (RGB1 & RGB2) are used
when devices are connected to the document camera’s two VGA inputs. No
devices are connected to document camera inputs in shared teaching spaces, so
ensure you only use the Main output!
Pressing F.A.M (Frame Accumulate Mode) reduces any roughness in the projected
image by digitally combining several images of the same document.
Pressing the Tele or Wide buttons enlarges or reduces the displayed image.
Auto Focus
Pressing the AF button activates auto focus.
Pressing the Contrast button increases the contrast of the object being displayed.
The contrast indicator light will turn on to indicate that you are in contrast mode.
Use this control when displaying paper-based documents.
Pressing the Posi/Nega button toggles the image between positive (normal view)
and negative mode (which is like a photographic negative).

Selecting a lamp
Document cameras have two sets of lamps - the upper lamp and base lamp:
Use the upper lamp to display paper documents or other three-dimensional objects.
Use the base lamp if you want to display transparencies - the base lamp turns the document
camera into a light box or an overhead projector.
Pressing the lamp button cycles through the three lamp settings - upper lamp, base lamp and
lamp off.
Using white balance
If the colours of image you are displaying look “wrong” - with a red or blue tinge for example - you
may have to manually adjust the document camera’s white balance.
To manually adjust white balance on the document camera:
1. Select & turn on the lamp that you will be using.
2. Zoom the document camera’s camera so as the white base fills the screen.
3. Press the White Balance button.
NOTE: The default white balance setting is automatic.
Adjusting the iris
Pressing the Open or Close iris buttons adjusts the brightness of the displayed image.
Pressing the Auto/Manual button toggles between automatic and manual iris adjustment.
You can tell what setting the iris is currently on by observing the following:
When set to automatic, the Auto/Manual button is not lit
When set to manual, the Auto/Manual button is lit.
NOTE: The default iris setting is automatic.

Using the remote control
Most document camera functions can be accessed from the front panel of the document camera.
However, some features (for example, manual focus) can only be accessed via the document
camera’s hand held remote control:
The document camera remote control is stored
in a drawer located on the front, right-hand side
of the document camera.
You need to push the drawer to access the
remote control.
Return the remote control to this drawer when
you have finished.

Using manual focus
Some objects can not be brought into focus using auto focus:
Objects with low contrast.
Objects with fine repeated patterns.
Reflective objects.
Moving objects.
Some three-dimensional objects.
If you cannot get an object to focus using auto focus, use the Near and Far
focus buttons on the hand held remote control.
