(distorsion en) barillet

I felt sure I'd heard a different term for this, but this one seems to be pretty universal; I've also found 'baril', but I think that is an unreliable translated source.

It is obvisouly talking about different forms of geometric distortion, 'barrel' and 'pincushion' are two of the common ones caused by optics.

Thanks, Thomas!
agree B D Finch : It seems Photoshop uses "barillet", but "tonneau" is nicer.

Thanks, B! It is also used by the major image processing software publisher I work for (native French)

(distorsion en) tonneau

"When straight lines are curved inwards in a shape of a barrel, this type of aberration is called “barrel distortion”. Commonly seen on wide angle lenses, barrel distortion happens because the field of view of the lens is much wider than the size of the image sensor and hence it needs to be “squeezed” to fit.

La première chose qui me vient à l'esprit quand je vois "barillet", c'est le barillet d'un pistolet (EN cylinder), qui est ... cylindrique, et ne représente apparemment pas bien la distorsion optique.
La distorsion en tonneau me semble plus parlante vu qu'on imagine la forme d'un tonneau, plus large au centre, plus étroit en haut et en bas.
Par ailleurs, un sens de "barillet" est "petit baril", ou petit tonneau, mais ce n'est guère utilisé dans ce sens.

Les chiffres :
"distorsion optique" "barillet" 405 Ghits
"distorsion optique" "tonneau" 238 Ghits

neutral Tony M : Note that the common pairing is 'barillet' / 'coussinet' — it seems as if perhaps the sector prefers the diminutives!
