3.4.1 Correction of Lens Distortion (L20-L23* and L22-L25* Only)

If you are using a camera with either the
L20-L23 or L22-L25 wide-angle lenses,
the image, particularly around the edges,
may be slightly distorted due to the extreme
angle of view of the lenses.
You can suppress this effect using software
(for example, in the browser) so that a
new and appropriately corrected image
can be displayed live. A side effect of this
correction, however, is that a cushion shape
appears around the edges of the image.
To hide this cushion effect, you simply have
to Zoom In on the image slightly. Although
this reduces the size of the captured area,
the image is almost distortion-free com-
pared to the original.
