pincushion distortion वाक्य

उदाहरण वाक्य

1. In other words, it is a lens with little or no barrel or pincushion distortion.
2. Barrel distortion typically will have a negative term for K _ 1 whereas pincushion distortion will have a positive value.
3. Since that time, most binocular manufacturers have followed Zeiss's example and added pincushion distortion to their optical design.
4. The reverse, in which the perimeter is magnified more than the center, is known as " pincushion distortion " ( figure 3b ).
5. :: : No, what I am said was that you cannot see any distortion from fixing pincushion distortion ( unless you are referring to a different issue than the'stretching').
6. Mathematically, barrel and pincushion distortion are quartic ( degree 4 ) term is significant : in the center, the degree 2 barrel distortion is dominant, while at the edge the degree 4 distortion in the pincushion direction dominates.
7. In the Distortions filter, barrel or pincushion distortion can be controlled, horizontal and vertical perspective may be changed, the image may be stretched and squeezed, the image may be skewed, h-bend can be controlled, and vignetting can be corrected.

9. For example, a greater degree of barrel and pincushion distortion is tolerated in lenses that span the focal length range from wide angle to telephoto with a focal ratio of 10?or more than would be acceptable in a fixed focal length lens or a zoom lens with a lower ratio.
10. The "'globe effect "', sometimes called the "'rolling ball effect "'or the "'spinning globe effect "', is an Zeiss ( Jena ) suggested adding some pincushion distortion to the optical design to eliminate the globe effect.
