  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. Instead of producing images with straight lines of perspective (rectilinear images), fisheye lenses use ...

  3. Panomorph - Wikipedia

    en.wikipedia.org/wiki/Panomorph

    A panomorph lens is a particular type of wide-angle lens specifically designed to improve optical performances in predefined zones of interest, or across the whole image, compared to traditional fisheye lenses. [1] [predatory publisher] Some examples of improved optical parameters include the number of pixels, the MTF or the relative illumination.

  4. PTGui - Wikipedia

    en.wikipedia.org/wiki/PTGui

    ptgui.com. PTGui is a panorama photo stitching program for Windows and macOS developed by New House Internet Services BV. PTGui was created as a GUI frontend to Helmut Dersch 's Panorama Tools. It features its own stitching and blending engine [2] along with compatibility to Panorama Tools.

  5. Distortion (optics) - Wikipedia

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

    Fisheye lenses are wide-angle lenses with heavy barrel distortion and thus exhibit both these phenomena, so objects in the center of the image (if shot from a short distance) are particularly enlarged: even if the barrel distortion is corrected, the resulting image is still from a wide-angle lens, and will still have a wide-angle perspective.

  6. Rectilinear lens - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_lens

    It allowed distortionless photos to be taken quickly for the first time, and was a standard lens design for 60 years. [1]: 59 As of 2020, the Laowa 9mm f/5.6 lens is the world's widest rectilinear lens for full frame cameras. [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images.

  7. 3D projection - Wikipedia

    en.wikipedia.org/wiki/3D_projection

    A 3D projection (or graphical projection) is a design technique used to display a three-dimensional (3D) object on a two-dimensional (2D) surface. These projections rely on visual perspective and aspect analysis to project a complex object for viewing capability on a simpler plane. 3D projections use the primary qualities of an object's basic ...

  8. Canon EF 8-15mm lens - Wikipedia

    en.wikipedia.org/wiki/Canon_EF_8-15mm_lens

    Canon EF 8-15mm lens. The EF8–15mm f/4L FISHEYE USM is a fisheye zoom lens for Canon digital single-lens reflex cameras (DSLRs) with an EF lens mount. It delivers 180° diagonal angle of view images for all EOS SLR cameras with imaging formats ranging from full-frame to APS-C, and provides 180° circular fisheye images for full-frame EOS models.

  9. Microsoft SenseCam - Wikipedia

    en.wikipedia.org/wiki/Microsoft_SenseCam

    Microsoft's SenseCam is a lifelogging camera with a fisheye lens and trigger sensors, such as accelerometers, heat sensing, and audio, invented by Lyndsay Williams, a patent [1] granted in 2009. Usually worn around the neck, Sensecam is used for the MyLifeBits project, a lifetime storage database. Early developers were James Srinivasan and ...
