Office Camera
An office camera is a digital camera device that performs tasks in offices such as document scanning, physical object imaging, video presentation and web conferencing.''Game Changer in Document Camera Industry'', retrieved October 6, 2010, http://allianceinternational.blogspot.com/2010/10/game-changer-in-document-camera.html It is similar to the document camera, which is normally used on podiums in classrooms and meeting rooms for presentations. An office camera typically has a compact form factor in order to be a commonplace desktop item. Commercial products, such as the HoverCam, can fit into pockets or briefcases, which makes them ideal for use on desktops or on-the-go. Generally, office cameras have least one high-resolution camera, which can be used in an "aerial" position to shoot video or still image pictures of documents or objects. In order to capture images with enough clarity, such cameras are expected to have high resolution, normally more than 2 megapixels at th ...

Document Imaging
Document imaging is an information technology category for systems capable of replicating documents commonly used in business. Document imaging systems can take many forms including microfilm, on demand printers, facsimile machines, copiers, multifunction printers, document scanners, computer output microfilm (COM) and archive writers. Document Imaging means the conversion of paper files (of any size or description) or microfilm / fiche to digital images. The image can be form in TEM (transmission electron microscope), here the image is form by scattering of electron beam. In TLM (transmission light microscope), the image is formed by the consequence observation of light. By the increasing thickness or density the image can be contrasted with acceleration voltage. Transitioning to digital in the legal sector The UK have been working slowly over the last decade to transition to digital processes. In 2013, the government launched an online claims portal to help keep track of and ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Conferencing
Web conferencing is used as an umbrella term for various types of online conferencing and collaborative services including webinars (web seminars), webcasts, and web meetings. Sometimes it may be used also in the more narrow sense of the peer-level web meeting context, in an attempt to disambiguate it from the other types known as collaborative sessions. The terminology related to these technologies is exact and agreed relying on the standards for web conferencing but specific organizations practices in usage exist to provide also term usage reference. In general, web conferencing is made possible by Internet technologies, particularly on TCP/IP connections. Services may allow real-time point-to-point communications as well as multicast communications from one sender to many receivers. It offers data streams of text-based messages, voice and video chat to be shared simultaneously, across geographically dispersed locations. Applications for web conferencing include meetings, tra ...

Document Camera
Document cameras, also known as visual presenters, visualizers, digital overheads, or docucams, are real-time image capture devices for displaying an object to a large audience. Like an opaque projector, a document camera is able to magnify and project the images of actual, three-dimensional objects, as well as transparencies. They are, in essence, high resolution web cams, mounted on arms so as to facilitate their placement over a page. This allows a teacher, lecturer or presenter to write on a sheet of paper or to display a two or three-dimensional object while the audience watches. Theoretically, all objects can be displayed by a document camera. Most objects are simply placed under the camera. The camera takes the picture which in turn produces a live picture using a projector or monitor. Different types of document camera/visualizer allow great flexibility in terms of placement of objects. Larger objects, for example, can simply be placed in front of the camera and the camera ...

Design
A design is a plan or specification for the construction of an object or system or for the implementation of an activity or process or the result of that plan or specification in the form of a prototype, product, or process. The verb ''to design'' expresses the process of developing a design. In some cases, the direct construction of an object without an explicit prior plan (such as in craftwork, some engineering, coding, and graphic design) may also be considered to be a design activity. The design usually has to satisfy certain goals and constraints; may take into account aesthetic, functional, economic, or socio-political considerations; and is expected to interact with a certain Environment (systems), environment. Typical examples of designs include architectural drawing, architectural and engineering drawing, engineering drawings, circuit diagrams, Pattern (sewing), sewing patterns and less tangible artefacts such as business process models. Designing People who produce designs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megapixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although ''sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position. Etymology The w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Point (typography)
In typography, the point is the smallest unit of measure. It is used for measuring font size, leading, and other items on a printed page. The size of the point has varied throughout printing's history. Since the 18th century, the size of a point has been between 0.18 and 0.4 millimeters. Following the advent of desktop publishing in the 1980s and 1990s, digital printing has largely supplanted the letterpress printing and has established the DTP point (DeskTop Publishing point) as the ''de facto'' standard. The DTP point is defined as of an international inch () and, as with earlier American point sizes, is considered to be of a pica. In metal type, the point size of the font describes the height of the metal body on which the typeface's characters were cast. In digital type, letters of a font are designed around an imaginary space called an '' em square''. When a point size of a font is specified, the font is scaled so that its em square has a side length of that parti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USB 2
Universal Serial Bus (USB) is an industry standard that establishes specifications for cables, connectors and protocols for connection, communication and power supply ( interfacing) between computers, peripherals and other computers. A broad variety of USB hardware exists, including 14 different connector types, of which USB-C is the most recent and the only one not currently deprecated. First released in 1996, the USB standards are maintained by the USB Implementers Forum (USB-IF). The four generations of USB are: USB 1.''x'', USB 2.0, USB 3.''x'', and USB4. Overview USB was designed to standardize the connection of peripherals to personal computers, both to communicate with and to supply electric power. It has largely replaced interfaces such as serial ports and parallel ports, and has become commonplace on a wide range of devices. Examples of peripherals that are connected via USB include computer keyboards and mice, video cameras, printers, portable media playe ...

Web Camera
A webcam is a video camera which is designed to record or stream to a computer or computer network. They are primarily used in videotelephony, livestreaming and social media, and security. Webcams can be built-in computer hardware or peripheral devices, and are commonly connected to a device using USB or wireless protocols. Webcams have been used on the Internet as early as 1993, and the first widespread commercial one became available in 1994. Early webcam usage on the Internet was primarily limited to stationary shots streamed to web sites. In the late 1990s and early 2000s, instant messaging clients added support for webcams, increasing their popularity in video conferencing. Computer manufacturers also started integrating webcams into laptop hardware. In 2020, the COVID-19 pandemic caused a shortage of webcams due to the increased number of people working from home. History Early development (early 1990s) First developed in 1991, a webcam was pointed at the Trojan R ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Universal Virtual Computer
UVC-based preservation is an archival strategy for handling the preservation of digital objects. It employs the use of a Universal Virtual Computer (UVC)—a virtual machine (VM) specifically designed for archival purposes, that allows both emulation and migration to a language-neutral format like XML. Background to the development of a UVC approach Digital preservation problem Preservation of digital resources is of a paramount importance for deposit libraries, research libraries, archives, government agencies, and actually most organizations.Lorie R. A., 2002. A Methodology and System for Preserving Digital Data. Proceedings of the 2nd ACM/IEEE-CS joint conference on Digital libraries, Portland, Oregon, USA. 14–18 July 2002. New York, NY: Association for Computing Machinery. pp. 312-319 The dominant approach to digital preservation is migration.
