  2. Rectilinear lens - Wikipedia

    en.wikipedia.org/wiki/Rectilinear_lens

    (a digital camera with an image sensor which size is similar to 35 mm film in film cameras as the standard film camera format) [2] The vast majority of video and still cameras use lenses that produce nearly rectilinear images. A popular alternative type of lens is a fisheye lens which produces a distinctly curvilinear, wide-angled result.

  3. Linear motion - Wikipedia

    en.wikipedia.org/wiki/Linear_motion

    The linear motion can be of two types: uniform linear motion, with constant velocity (zero acceleration); and non-uniform linear motion, with variable velocity (non-zero acceleration). The motion of a particle (a point-like object) along a line can be described by its position x {\displaystyle x} , which varies with t {\displaystyle t} (time).

  4. 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 ...

  5. Light field camera - Wikipedia

    en.wikipedia.org/wiki/Light_field_camera

    Lytro Illum 2nd generation light field camera Front and back of a Lytro, the first consumer light field camera, showing the front lens and LCD touchscreen. A light field camera, also known as a plenoptic camera, is a camera that captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the precise direction that the light rays are ...

  6. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    The effect is especially noticeable the closer the camera is to the subject, as its amount increases the shorter the focal length is at the same field size. One notable director that frequently employs rectilinear ultra wide angle lenses in order to achieve a distinctive signature style defined by extreme perspective distortion is Terry Gilliam.

  7. Camera lens - Wikipedia

    en.wikipedia.org/wiki/Camera_lens

    Different kinds of camera lenses, including wide angle, telephoto and speciality. A camera lens (also known as photographic lens or photographic objective) is an optical lens or assembly of lenses (compound lens) used in conjunction with a camera body and mechanism to make images of objects either on photographic film or on other media capable of storing an image chemically or electronically.

  8. Coincidence rangefinder - Wikipedia

    en.wikipedia.org/wiki/Coincidence_rangefinder

    Coincidence rangefinders were important elements of fire control systems for long-range naval guns and land-based coastal artillery circa 1890–1960. They were also used in rangefinder cameras. A stereoscopic rangefinder looks similar, but has two eyepieces and uses a different principle, based on binocular vision. The two can normally be ...

  9. Motion analysis - Wikipedia

    en.wikipedia.org/wiki/Motion_analysis

    The motion field that corresponds to the relative motion of some 3D point. A video camera can be seen as an approximation of a pinhole camera, which means that each point in the image is illuminated by some (normally one) point in the scene in front of the camera, usually by means of light that the scene point reflects from a light source. Each ...
