  2. Fisheye lens - Wikipedia

    en.wikipedia.org/wiki/Fisheye_lens

    A fisheye lens is an ultra wide-angle lens that produces strong visual distortion intended to create a wide panoramic or hemispherical image. [4] [5]: 145 Fisheye lenses achieve extremely wide angles of view, well beyond any rectilinear lens.

  3. Distortion (optics) - Wikipedia

    en.wikipedia.org/wiki/Distortion_(optics)

    In geometric optics, distortion is a deviation from rectilinear projection; a projection in which straight lines in a scene remain straight in an image.It is a form of optical aberration that may be distinguished from other aberrations such as spherical aberration, coma, chromatic aberration, field curvature, and astigmatism in a sense that these impact the image sharpness without changing an ...

    en.wikipedia.org/wiki/Panomorph

    The display is optimized to keep advantage of the improved performance in the zone of interest created by the panomorph lenses as opposed to algorithms for fisheye lenses which employ a linear mapping function to de-warp the image without any considerations for their departure from a perfect linear mapping (distortion).

  5. Curvilinear perspective - Wikipedia

    en.wikipedia.org/wiki/Curvilinear_perspective

    Curvilinear barrel distortion Curvilinear pincushion distortion. Curvilinear perspective, also five-point perspective, is a graphical projection used to draw 3D objects on 2D surfaces, for which (straight) lines on the 3D object are projected to curves on the 2D surface that are typically not straight (hence the qualifier "curvilinear" [citation needed]).

  6. Ultra wide angle lens - Wikipedia

    en.wikipedia.org/wiki/Ultra_wide_angle_lens

    Notice the barrel distortion typical for fisheye lenses in the curvilinear image. While this example has been rectilinear-corrected by software, high-quality wide-angle lenses are built with optical rectilinear correction. Bearing 8/3.5 fisheye. A capture of an entire scene, including the sun is shown (180-degree circular fisheye).

  7. Rectilinear lens - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_lens

    In photography, a rectilinear lens is a photographic lens that yields images where straight features, such as the edges of walls of buildings, appear with straight lines, as opposed to being curved. In other words, it is a lens with little or no barrel or pincushion distortion. At particularly wide angles, however, the rectilinear perspective ...

  9. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    The mood effect of perspective distortion achieved by rectilinear extreme wide-angle lenses is that the resulting image looks grotesque and unsettling, while not looking as unrealistic as curvilinear fisheye lenses which display barrel distortion. The effect is especially noticeable the closer the camera is to the subject, as its amount ...
