Auto Trapezoid Correction
The PC Image Mode's auto trapezoid correction feature detects the intended subject of an
image recorded with the PJ Camera's Business Shot, and automatically corrects any distortion
in the image.

(recorded image)
Auto trapezoid correction is turned on under the initial default settings of the PC Image
Mode. You can use the [Image] tab of the operating environment dialog box to turn auto
trapezoid correction on or off. For more information, see "PJ Camera Software Operating
Environment" (page 110).
Auto trapezoid correction may not be possible for the following types of image files.
• Image files recorded in any PJ Camera mode besides the Business Shot.
• Image files for which PJ Camera Software cannot detect any keystoning
• Images of 3-dimensional subjects, scenery, or other subjects that do not include a
document page, whiteboard, or other rectangular shape, images drawn or created with a
computer, etc.
• Trapezoid corrected or contour extracted image files (page 32)
In this case, the image file contents are projected, without modification.
