Curved vertical distortion that creates a barrel shape. It occurs when using a wide-angle lens.
Optical distortion that is causes straight lines near the corners of the image area to curve inward, like the ends of a barrel when viewed from the side. Compare to " pincushion distortion".
Lens-caused effect showing the edges of subject bowing outward.
Curving distortion to vertical lines caused by wide angle lenses
A distortion, or aberration
(and pincushion distortion). Image where the edges curve outwards (image where edges curve inwards).
A distortion where parallel lines in an image appears to bow outwards at the edges of the image. Like in a wooden barrel.
Some lenses will create what is known as "barrel distortion" around the edges of a picture. Any straight lines will appear slightly curved, due to the spherical shape of the lens.
Image distortion produced when the position of the camera lens is at its widest angle. Lines you expect to appear perpendicular are not. It is most noticeable when you have a straight edge near the side of the frame, such as when taking a wide angle shot of a building. Barrel distortion causes the edges of an image to look curved or at a skewed angle. Most barrel distortion can be corrected using image editing software.
In video, a form of geometric distortion in which straight lines bulge or bow outward toward the edges of the screen, e.g. making a square look barrel shaped. See: Pincushion Distortion.
Aberration with projectors where the margin lines of the image are convex. This is caused by aberrations of the lens. Opposite cushion distortion.
Image distortion that spreads the center dimensions of the picture.
one of the common lens aberrations, where straight lines at the edge of the field are caused to bend into the shape of a barrel.
A lens aberration that causes straight lines in an image to bow outward, especially near the edges. Compare to pincushion distortion.
Lens aberration (distortion) where straight lines are formed as curved lines in the image. These barrel shaped lines are most noticeable along the edges of the photo. (see Aberration & Pincushion effect )
Image distortion caused by a lens, where the edge bows outwards like a fisheye or wide-angle lens's image.
A lens aberration where parallel lines at the edge of the image area appear to bow outwards.
is a distortion in the monitor due to non uniform scanning which causes the image to bulge outwards like a barrel.
Form of video distortion in which lines on the screen bow or bend outward toward the edges of the screen when they should be straight lines with no curve (or curved lines are curved more than they should be).
A lens aberration or defect that causes straight lines to bow outward away from the center of the image.
An optical imperfection that causes an image to bulge convexly on all sides similar to a barrel.
A distortion in which straight lines not passing through the center of the image bend outward (away from the center of the image). The curvature becomes more pronounced further from the center. This is the opposite of pincushion distortion.
Image distortion that spatially expands the center of a display and contracts the corners to make rectangular display objects appear barrel shaped.
Straight lines are bowed in at the edges of the picture frame re sembling the sides of a barrel; pres ent in small amounts in some wideangle or wideangle-zoom lenses, bu~ uncorrected in fisheye lenses.
