Precautions when Using the PJ Camera Software
Tip
Check the following points if you suddenly start to have problems with contour detection.
Has there been a change in the conditions under which you are using the camera?
Perform camera position adjustment.
Have you changed to a different type of document?
Check to make sure that the document contents conform to contour extraction requirements.
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.
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.
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.
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.
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.
A slow shutter speed setting is used in order to produce high-resolution images. Avoid
shaking or moving the camera while recording images.
