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.
Image stabilization (IS) is a family of techniques that reduce blurring associated with the motion of a camera or other imaging device during exposure.. Generally, it compensates for pan and tilt (angular movement, equivalent to yaw and pitch) of the imaging device, though electronic image stabilization can also compensate for rotation about the optical axis ().
It is commonly suggested [citation needed] to correct perspective using a general projective transformation tool, correcting vertical tilt (converging verticals) by stretching out the top; this is the "Distort Transform" in Photoshop, and the "perspective tool" in GIMP.
Boeing said this month it has added new training material for manufacturing and quality roles averaging about 20 to 50 more training hours per employee, while more than 7,000 new tools and ...
DxO ViewPoint allows users to correct the horizon, keystoning, volume distortion (volume anamorphosis ), and a number of lens distortions automatically or through sliders. Lens distortions include barrel, pincushion, and fisheye.
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.
Camera lucida in use. A camera lucida is an optical device used as a drawing aid by artists and microscopists . The camera lucida projects an optical superimposition of the subject being viewed, onto the surface upon which the artist is drawing. The artist sees both scene and drawing surface simultaneously, as in a photographic double exposure.
Ophthalmology. In ophthalmology, horror fusionis is a condition in which the eyes have an unsteady deviation, with the extraocular muscles performing spasm-like movements that continuously shift the eyes away from the position in which they would be directed to the same point in space, giving rise to diplopia. Even when the double vision images ...
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 .
A review by Imaging Resource emphasised its "excellent high ISO performance" and "excellent print quality". In September 2010 Pentax announced the K-r, a 6 frames per second 12.4 megapixel camera and the K-5, a 7 frames per second 16.3 megapixel camera. These cameras use a new, faster autofocus system, SAFOX IX.
