Barrel distortion

From Biocrawler, the free encyclopedia.

Barrel distortion is a divergence from the rectilinear projection in geometric optics where image magnification decreases with increasing distance from the optical axis.

The visible effect is that lines that do not go through the centre of the image are bowed outwards, towards the edge of the image.
