Universalzoom
(Digital cameras and photo printers) Zoom which has a focal length as well in the wide angle area as if in the tele area. Universal zoom indicates typically zoomobjectives which have focal length from 28 to 200 mm.

Unsharp Masking
(Digital cameras and photo printers) Often abbreviated USM. Describes an image focusing process. The quality of the result depends on the characteristics of the algorithm used.

Update
(Digital cameras and photo printers) An updated version of a software program.

Upgrade
(Digital cameras and photo printers) A new improved version of hardware or software that is already available.

Upload
(Digital cameras and photo printers) Process of copying a file from a computer to a remote computer. Opposite of download.

URL
(Digital cameras and photo printers) Unified Resource Locator. Address system for Internet sites.

USB
(Digital cameras and photo printers) The Universal Serial Bus is probably going to replace the serial and parallel interfaces. USB enables the effortless connection of peripheral devices without the need to install cards into the computer or reconfigure parts of the operating system. The most important advantages are: the support of Plug and Play, hot plugging, automatic configuration of external devices upon connection (no re-start necessary), faster data transfer and the possible operation of up to 127 devices from a single port. USB 2.0 uses a much higher bandwidth and is up to 40 times faster than the original standard. It further benefits from being backwards compatible with existing USB technology, so older devices will still work with USB 2.0 at a so called 'Normal Speed' which is equivilant to the USB 1.1 specification while newer devices which are USB Hi-Speed 2.0compliant will profit from the much faster data transfer speed of USB Hi-Speed 2.0.

USB AutoConnect
(Digital cameras and photo printers) USB Mass Storage Class.

USB Mass Storage Class
(Digital cameras and photo printers) With USB Mass Storage Class support, the camera (or any other compatible device) is automatically displayed as an external drive. It can then be easily accessed in any program as a regular drive. Since most operating systems contain the generic Mass Storage Class driver, the camera is recognised without any driver having to be installed. Also called USB Storage Class or USB AutoConnect.

USB Storage Class
(Digital cameras and photo printers) USB Mass Storage Class.

Utility
(Digital cameras and photo printers) A program that performs special tasks for the operating system, for example: file administration, controlling a digital camera, a CD-ROM drive or printer.

UXGA
(Digital cameras and photo printers) Ultra Extended Graphics Array. This refers to images with a resolution of 1,600 x 1,280 pixels. (QXGA, SVGA, SXGA, VGA, XGA)

VGA
(Digital cameras and photo printers) Video Graphics Array. Refers to a display screen with a resolution of 640 x 480 pixels. (QXGA, SVGA, SXGA, UXGA, XGA)

Video CCD
(Digital cameras and photo printers) Describes a CCD specially developed for television and video, also used in digital still cameras. (Progressive CCD)

Video output
(Digital cameras and photo printers) Interface that connects a digital camera with a TV or video recorder.

Viewfinder
(Digital cameras and photo printers) Part of the camera through which you can see the image. The well-known viewer types with digital cameras are: Single-lens reflex viewfinder, TTL-viewfinder, LCD color monitor and the electronical video viewfinder.

Viewfinder
(Film cameras) The camera window through which you see the rectangular frame used to view and compose your subject.

Vignetting
(Digital cameras and photo printers) Fading off the sides of a picture into plain white or black instead of having abrupt edges. Also unintentional loss of brightness at the edge of the image. Wide angle lenses are particularly susceptible. However, the problem can be more or less avoided by removing the elements causing the effect, such as a filter with a frame that is too large or ill-fitting lens hood.

Virus
(Digital cameras and photo printers) Describes a part of a computer program that usually causes damage or destruction of software and/or data.

VR
(Digital cameras and photo printers) Short for: Vibration Reduction

White balance
(Digital cameras and photo printers) The adjustment of a digital camera to the respective type of light (colour temerature) such as daylight, overcast, tungsten, and fluorescent light for even truer colours. Or to create a different, striking effect.

WIA
(Digital cameras and photo printers) Short for: Windows Image Acquisition.In the latest operating system from Microsoft (Windows ME/XP) built-in software plug-in for operating scanners and cameras on operating system level. WIA can be seen as a development of TWAIN, because it needs a driverinstallation, oposite to PTP, but already operates on operating system level.

Wide angle
(Digital cameras and photo printers) Classification for focallength of objectives. Als wide angel objectives are indicated all objectives with a focal length of 35 mm or less. Typical properties of a wide angle objective are the great angle of view (ca. 65 bis 180° according the focal length) and super wide angle (24 mm or less).

Wide angle
(Digital cameras and photo printers) Wide angle lenses are those with focal lengths of 35 mm* and lower. The typical qualities of these lenses are a wide viewing angle, (60° to 180°) and a large depth of field. Standard wide angle lenses are classified as having focal lengths of 28 to 35 mm*; super wide angle lenses have values of 24 mm* or less. (Tele, zoom) (* Refers to a 35 mm camera)

Wide-angle converter
(Digital cameras and photo printers) Lens attachment that reduces the focal length. (Macro converter, tele converter)

Wide-angle focal length
(Film cameras) The focal length (also known as short focal length) at which the lens takes in a relatively large section of the scene. Most point-and-shoot zoom lenses start out at a wide-angle setting (38mm, 28mm), and most non-zoon cameras have wide-angle lenses (35mm, 32mm).

Windows (95-98-2000- NT-XP-ME)
(Digital cameras and photo printers) Graphic-based operating environment developed by Microsoft.

World Wide Web
(Digital cameras and photo printers) Currently the most popular service offered through the Internet. The WWW provides the possibility to transmit files with multimedia content (texts, sounds, pictures).

Write cancel
(Digital cameras and photo printers) This mode allows image data in the buffer memory to be deleted and cancels the saving process to the memory card. The camera is thereby immediately ready to shoot again. This function is especially useful in cameras with high-speed sequence shooting.

WWW
(Digital cameras and photo printers) World Wide Web.

xD-Picture Card
(Digital cameras and photo printers) An innovative memory card standard developed by Olympus and Fujifilm, launched in 2002. Particularly small digital memory media for digital cameras that is very durable and robust, and allows speedy data transfer rates. Capacities of up to 8 GB will be possible in the future. (Max. available capacity 2002: 256 MB).

XGA
(Digital cameras and photo printers) Extended Graphics Array. A graphics standard developed by IBM, which allows the display of 1,024 x 768 pixels with up to 65,535 colours. (SVGA, SXGA, UXGA, VGA)

Yahoo!
(Digital cameras and photo printers) Well-known Internet search engine.

ZIP
(Digital cameras and photo printers) File format used for data compression.

ZIP-Drive
(Digital cameras and photo printers) A device that allows the storage of up to 750 MB of data.

Zoom factor
(Digital cameras and photo printers) Ratio between the largest and smallest focal length. Indicates as well the maximum enlarge factor.So has a zoomobjective with a focal length from f.i. 38 to 380mm the disposal of a 10x zoom, a focal length from 38 to 72 mm has a disposal of 2x zoom.

Zoom lens
(Digital cameras and photo printers) A type of lens that allows the photographer to get closer (zoom) to a subject. By adjusting the focal length (manually or mechanically), the degree of magnification can be altered. This feature is particularly useful for picking out subjects at a distance. The zooming power of a camera can usually be read on its lens; 3x (e.g. 35 - 105 mm*) is a common zoom level that provides good magnification. However, other cameras offer up to 10x magnification or more, which increases the focal length ten times (e.g. 38 – 380 mm*). When using such high magnification lenses, an optical image stabiliser or tripod help to ensure sharp, clear results. (Lenses, tele, wide, digital zoom, focal length) (* Refers to a 35 mm camera)

Zoom lens
(Film cameras) A lens of adjustable focal length. You can zoom to increase or decrease the lens' magnifying power, making the subject bigger or smaller in the frame.
