Term: Distortion, geometric

Distortion in which the true geometry of an object is not properly represented in the digital image, e.g., barrel (sides of a square bulge out) or pincushion (sides of a square curve inward). Some factors that can cause geometric distortion include: system optics, sensor defects, or mis-position of the image plane relative to the plane of the object being digitized.
