OIS may mean:

Samsung Galaxy

Samsung Galaxy (stylized as Samsung GALAXY or SAMSUNG Galaxy) is a series of mobile computing devices designed, manufactured and marketed by Samsung Electronics. The product line includes the Galaxy S series of high-end smartphones, the Galaxy Tab series of tablets, the Galaxy Note series of tablets and phablets with the added functionality of a stylus and the first version of the Galaxy Gear smartwatch, with later versions dropping the Galaxy branding.

Samsung Galaxy devices have traditionally used the Android operating system produced by the Open Handset Alliance led by Google, usually with a custom user interface called TouchWiz. This tradition was broken at CES 2016 with the announcement of the first Galaxy-branded Windows 10 device, the Samsung Galaxy TabPro S.

Since August 2015, all the smartphones of the Galaxy series are categorized in the following way:

Image stabilization

Image stabilization (IS) is a family of techniques used to 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, although electronic image stabilization can also be used to compensate for rotation. It is used in image-stabilized binoculars, still and video cameras, astronomical telescopes, and also smartphones, mainly the high-end. With still cameras, camera shake is particularly problematic at slow shutter speeds or with long focal length (telephoto or zoom) lenses. With video cameras, camera shake causes visible frame-to-frame jitter in the recorded video. In astronomy, the problem of lens-shake is added to by variations in the atmosphere over time, which will cause the apparent positions of objects to change.

Application in still photography

In photography, image stabilization can often permit the use of shutter speeds 2–4.5 stops slower (exposures 4–22.5 times longer), although even slower effective speeds have been reported.

Image

An image (from Latin: imago) is an artifact that depicts visual perception, for example a two-dimensional picture, that has a similar appearance to some subject—usually a physical object or a person, thus providing a depiction of it.

Characteristics

Images may be two-dimensional, such as a photograph, screen display, and as well as a three-dimensional, such as a statue or hologram. They may be captured by optical devices – such as cameras, mirrors, lenses, telescopes, microscopes, etc. and natural objects and phenomena, such as the human eye or water.

The word image is also used in the broader sense of any two-dimensional figure such as a map, a graph, a pie chart, or a painting. In this wider sense, images can also be rendered manually, such as by drawing, the art of painting, carving, rendered automatically by printing or computer graphics technology, or developed by a combination of methods, especially in a pseudo-photograph.

A volatile image is one that exists only for a short period of time. This may be a reflection of an object by a mirror, a projection of a camera obscura, or a scene displayed on a cathode ray tube. A fixed image, also called a hard copy, is one that has been recorded on a material object, such as paper or textile by photography or any other digital process.

LG G2

The LG G2 is an Android smartphone developed by LG Electronics. Serving as a successor to 2012's Optimus G and the 2013 Optimus G Pro phablet, the G2 was unveiled at a press event in New York City on 7 August 2013, and first released in September 2013. The G2 is primarily distinguished by software features that LG billed would "learn" from users, a high fidelity sound system designed to produce higher quality audio, a 5.2 in (130 mm) 1080p screen with technology that the company claimed would improve energy efficiency and reduce the size of the bezel around it, along with the unique placement of its power and volume keys—eschewing their typical location on the edge of a smartphone by placing them on the rear below the camera lens.

The device was released to mostly positive reception; the G2 was universally praised for LG's efforts to produce a more seamless and compact design, its high performance, the quality of its display and camera, along with its long-lasting battery. Critics were divided on certain aspects of its design, such as its rear button layout, and its plastic chassis—which was panned for closely resembling recent Samsung Galaxy products and being a regression from the glass-based chassis of the Optimus G. Similarly, while its software and user interface was praised for its usability and large number of customization options, some reviewers felt that the software suffered from feature creep and contained notable usability regressions in comparison to "stock" Android.
