DxO ViewPoint is image geometry and lens defect correction software developed by DxO. It is designed to automatically straighten distorted perspectives caused by the lens used and the position of the photographer.
Prism correction. Prism lenses (here unusually thick) are used for pre-operative prism adaptation. Eye care professionals use prism correction as a component of some eyeglass prescriptions. A lens which includes some amount of prism correction will displace the viewed image horizontally, vertically, or a combination of both directions.
When the eye position is fully corrected (for example after surgical alignment of the eyes) or when the patient is provided with the best achievable prism correction, the patient does not experience binocular fusion and, instead, sees a double image that is very close to the fixation image and is perceived as "dancing around" it.

The Olympus E-510 (or Olympus EVOLT E-510 in North America) is a 10-megapixel digital single-lens reflex (DSLR) camera oriented to the "prosumer ...
Flat-field correction (FFC) is a digital imaging technique to mitigate the image detector pixel-to-pixel sensitivity and distortions in the optical path. It is a standard calibration procedure in everything from personal digital cameras to large telescopes.
GIMP includes manual lens distortion correction (from version 2.4). PhotoPerfect has interactive functions for general pincushion adjustment, and for fringe (adjusting the size of the red, green and blue image parts).
Image Geometry Correction (often referred to as Image Warping) is the process of digitally manipulating image data such that the image’s projection precisely matches a specific projection surface or shape.
Incomitant strabismus cannot be fully corrected by prism glasses, because the eyes would require different degrees of prismatic correction dependent on the direction of the gaze. Incomitant strabismus of the eso- or exo-type are classified as "alphabet patterns": they are denoted as A- or V- or more rarely λ -, Y- or X-pattern depending on the ...
Wollaston's design used a prism with four optical faces to produce two successive reflections (see illustration), thus producing an image that is not inverted or reversed. Angles ABC and ADC are 67.5° and BCD is 135°.
The TTL metering is semi-spot in nature and works through a prism incorporated in the viewfinder condenser/screen assembly. The later Canon F-1 has a similar prism for metering in its removable screen.
