Anti-shake (image stabilization)
| Lens Glossary |
Also known as image stabilization (is), vibration reduction (vr), or simply image stabilization, anti-shake technology is a method of reducing the effects of camera movement on the photographic image. image stabilization can be achieved in the lens or in the camera body. in-camera image stabilization is achieved by mounting the camera sensor on a “floating” micro-geared stage that rapidly shifts the sensor in the opposite direction of the camera`s movement, which effectively cancels out the image movement. with in-camera image stabilization, the benefits of the system can be realized with any attached lens.

Stabilization, английский
- Стабилизация
- The action of improving the stability of the sloped surface of a soil mass.
- Стабилизация (оползня, грунта) ~ of effluent стабилизация сточных вод bank ~ берегоукрепление bed ~ крепление русла
- A technique that increases sharpness and fidelity by compensating for some effects that camera movement has on images in videos. stack (n)
- The action undertakes a country when it buys and sells its own currency to protect its exchange value. actions registered competitive traders undertake by on the nyse to meet the exchange requirement that 75% of their traded be stabilizing, meaning that sell orders follow a plus tick and buy orders a tick. actions a managing underwriter undertake so that the market price does not fall below the public offering price during the offering period.
Technology, английский
- The use of tools and knowledge to meet human needs.
- Техника; технология
- Техника (означает все знания или неотъемлемую часть знаний о: научных принципах или открытиях; промышленных процессах; материальных и энергетических ресурсах; средствах транспорта и связи, постольку, поскольку эти знания непосредственно касаются развития производства товаров или сферы услуг; документы юнеско)
- N технология speech recognition ~ технология распознава- ния речи3
- Национальный институт стандартов и технологии
- Технология
- The body of knowledge about, and the systematic study of, methods, techniques and hardware applied in the adaptation of the physical environment to man`s needs and wants. the application of scientific knowledge to build or improve the infrastructure of agriculture, industry government and daily life. (technology must not be confused with the very infrastructure it generates). technology has autocatalytic properties. it favores the use of technical devices and processes even in solving social problems, e.g., by using fertilizers to enhance agricultural production rather than a different form of work organization, by using computers for national planning rather than decentralized decision making processes.
- The practical application of knowledge to achieve particular tasks that employs both technical artefacts (hardware, equipment) and (social) information (‘software’, know-how for production and use of artefacts). supply push aims at developing specifi c technologies through support for research, development and demonstration. demand pull is the practice of creating market and other incentives to induce the introduction of particular sets of technologies (e.g., low-carbon technologies through carbon pricing) or single technologies (e.g., through technology-specifi c feed-in tariffs).

Focal length magnifier, английский
Also known as magnification factor or crop factor, this term is used to describe the angle of view (aov) of a lens used on a dslr in relation to how it would appear on a full-frame 35mm camera. as an example, compact dslrs contain sensors that are about 50% smaller than a standard 35mm frame. as a result, the effective focal length and aov of a 50mm lens on a compact dslr would be reduced, or cropped to the equivalent of a 75mm lens. canon eos rebels and other compact canon dslrs have a 1.6x magnification factor, which would make a 50mm lens effectively an 80mm lens. for more on this subject, see the eplora article, “understanding crop factor.”
Af servo, английский
Also known as continuous focus, af servo is maintained by partially pressing the camera`s shutter release button, which enables you to maintain focus continuously on a moving subject as the subject moves within the frame. shutter-response times are usually faster in af servo, since the subject is already in focus. for more on this subject, see the explora article, “choosing autofocus modes.”
