z As a general rule, operations using the shortcut menu that appears when you right-click
with the mouse are not included. For information about the shortcut menu, see “Chapter 4
Reference”.
■ MULTI PJ Camera
The term “PJ Camera” in this manual refers to the camera unit of the Multi PJ Camera
System.
■ Projection
PJ Camera Software is basically software for projecting images from a projector. Because of
this, the term “projection” is used in this manual to refer to operations that actually cause the
image to fill the computer screen (without actually projecting it).
Startup Modes and this Manual
PJ Camera Software has two startup modes: a Multi PJ startup mode and a Business
Document startup mode (“PJ Camera Software Startup Modes” page 13). The startup mode
you select determines the PJ Camera Software functions that are available to you.
z All of the explanations in this manual apply when you start up PJ Camera Software in the
Multi PJ startup mode.
z Only functions and explanations with next to their title apply when you start up PJ
Camera Software in the Business Document startup mode.
z Descriptions of items that explain particular differences between the Multi PJ and the
Business Document startup modes are presented as shown below.

Precautions when Using the PJ
Camera Software
PJ Document Stage
z Never write on the document stage and take care to guard against scratching or otherwise
damaging it. Writing or other marks on the document stage can interfere with projection in
the Document Camera Mode and scanning in the Scanner Mode.
z External Light
Room illumination, sunlight, or light from some other source shining onto the document
stage during a Document Camera Mode or Scanner Mode image recording operation can
cause white out and other image abnormalities.
Document Camera Mode
The Multi PJ Camera System automatically monitors the status of the document stage in
order to optimize contour extraction and automatic image recording operations under a variety
of different conditions. Because of this, you should adjust the camera position whenever
recording conditions change or when you move the camera due to a mode change, etc.
■ Automatic Image Recording
The automatic image recording function detects changes in brightness and contrast. Though
the Multi PJ Camera System can adapt to a wide range of conditions, automatic image
recording may not be possible under the following conditions.
z In a room where there is insufficient lighting to detect contours
z In a room where there are large fluctuations in the lighting level
z A document that is smaller than the specified size
In the above cases, use manual recording.
Tip
If the shutter releases even though there is nothing on the document stage, check the
following.
z If the document stage is badly damaged, have it repaired.
z If the document stage is very dirty, clean it.
z If there has recently been a change in the camera recording conditions, perform camera
position adjustment.

Precautions when Using the PJ Camera Software
■ Contour Extraction
Contour extraction uses brightness contrast to extract the rectangular shapes in an image.
Though the Multi PJ Camera System can adapt to a wide range of conditions, certain types
of documents may not be compatible with automatic contour detection. The following are the
conditions that promote successful automatic contour detection.
z Make sure the room is lit sufficiently.
z Place the document in the center of the document stage, and make sure that no part of it
is extending off of the stage.
z Make sure the document is free of creases and curls, and is either rectangular or square.
z Make sure the document is free of creases and wrinkles.
z Use only documents that are within the stipulated range of sizes (from business card size
to A4 (210 × 297mm)(8.3 × 11.7inch)/Letter size).
z Use documents whose color provides sufficient contrast with the document stage color. Also,
the color surface of the table where the PJ Camera Stand is located should be a different
color from the document stage.
z Place the PJ Camera Stand on a surface that does not reflect light.
z When placing a document onto the document stage, make sure the document is relatively
straight (tilted no more than about 30 degrees).
Tip
Check for the following if you experience occasional contour detection problems.
z In the case of a color document, is there sufficient color contrast around the contours?
If not, use a setting that does not perform contour extraction.
z Is room lighting too dim to allow adequate contour contrast detection?
Increase the level of room lighting or use a setting that does not perform contour extraction.
z Is part of the document outside of the document stage area?
Re-position the document taking care to ensure that no part of the document extends past
the edges of the document stage. Make sure that the entire document is within the area of
the document stage.
z The document is curled or bent.
Flatten the document so it forms a rectangle or square.
Tip
Check the following points if contour detection does not work at all.
z Is the document smaller than the specified size?
If it is, extraction cannot be performed.
z Is the document in the center of the document stage with no part of the document
extending off the sides of the stage?
Position the document in the center of document stage and ensure that no part of it extends
off the sides.
8
Precautions when Using the PJ Camera Software
Tip
Check the following points if you suddenly start to have problems with contour detection.
z Has there been a change in the conditions under which you are using the camera?
Perform camera position adjustment.
z Have you changed to a different type of document?
Check to make sure that the document contents conform to contour extraction requirements.
z Is an edge of the document running along a joint of the document stage?
Reposition the document so its edges do not run along any document stage joint.
z Is the document positioned in the center of the document stage?
Make sure that the document is positioned so one part of it is located on the cross mark
in the center of the document stage.
z Is the document too small?
Use the “Small Document” setting.
Projection Area Capture
When capturing the image area, compose the image so the entire projection area fits within it.
Adjust the position of the projector to make sure that the projected image is rectangular or
square.
z The PJ Camera Software corrects for distorion of the projection image. This can cause
written text or graphics in the combined Projection Area Capture image to appear somewhat
different from the original.
z For best results, make sure to check for the following when composing an image for
Projection Area Capture.
• Make sure that the projection area is included within the image.
• Make sure that the projection area fills the entire image.
• Make sure that the center of the image is located within the projection area on the
whiteboard.
• Make sure that all of the projection area is on the whiteboard, and that it forms a
rectangular or square shape.
• Make sure there is sufficient contrast around the periphery of the projection area.
• Make sure there is no light from a fluorescent or incandescent light source shining into
the projection area.
z A slow shutter speed setting is used in order to produce high-resolution images. Avoid
shaking or moving the camera while recording images.

Precautions when Using the PJ Camera Software
Board Area Capture
When capturing the board area, compose the image so the entire board area fits within it.
For best results, make sure to check for the following when composing an image for Board
Area Capture.
z Make sure that the whiteboard contour fits within the image.
z Make sure the whiteboard fills the entire image.
z Make sure that the center of the image is located within the whiteboard area.
z Make sure there is sufficient contrast around the periphery of the whiteboard.
z Make sure there is no light from a fluorescent or incandescent light source shining onto the
whiteboard.
z Make sure that the angle between the projector and the whiteboard is no greater than 30
degrees.
A slow shutter speed setting is used in order to produce high-resolution images. Avoid
shaking or moving the camera while recording images.

29
Using the PJ System Like an OHP Projector (Document Camera Mode)
Document camera images and Rough (Monitor) Images
When you place a document on the PJ Camera Stand in the Document Camera Mode, the
PJ Camera records its image (recorded image). Then PJ Camera Software automatically
performs a number of procedures on the image data, before finally projecting a document
camera image.
During the time it takes for these procedures to be performed, PJ Camera Software will
project a rough version of the image, which is similar to the image that appears on the PJ
Camera’s monitor screen. This is the rough (monitor) image. The rough (monitor) image will
be replaced by the document camera image as soon as it becomes available.
The following shows the flow starting with recording of an image and ending with projection
of the document camera image.
Document Recording with the PJ Camera (Recorded Image)
LRough (monitor) image is projected.
Contour Extraction
Extracts the document portion from the recorded image and
adjusts its orientation so it is straight. See “What is contour
extraction?” for more information.
z When you start up PJ Camera Software in the Business
L
Document startup mode, contour extraction is turned off
under initial default settings. To turn on automatic contour
extraction, display the operation bar, and then select
[Trapezoid Correction On] on the [Image] menu (so there is a
check mark next to Trapezoid Correction). You can also
toggle trapezoid correction on and off by pressing the space
bar on your computer.
