DIGITAL TECHNOLOGY MADE SIMPLER
. Imaging systems vary in their engineering sophistication, the quality of their sensory devices, the character of the software that is brought to bear to streamline the process, and the speed with which the system can carry out the conversion of a given source or collection of sources.
Handbook for Digital Projects - Section VI Technical Primer
. The common digital imaging sensors are: CCD: Charged coupled devices, or CCDs, used in both flatbed scanners and digital cameras PMT: Photo-multiplier tubes, or PMTs, used in drum scanners CMOS: Complementary metal oxide semiconductors, or CMOS chips, used in low-end flatbed scanners and low-end digital cameras.. Color gamuts are illustrated graphically to compare different color spaces, color systems, or devices.. Accuracy of Color Managing the accuracy of color rendition for digital images is complex, involving the adjustment and calibration of computer monitors, the adjustment of scanner controls, the correction or enhancement of images using image processing software, the adjustment and calibration of output devices, and the use of color management software.. This software transforms images between different color spaces to correct for differences in the color gamuts of scanners, monitors, and output devices.
Digital memory terms and concepts - Chapter 15: DIGITAL STORAGE (MEMORY) - Volume IV - Digital
. Most, if not all, memory devices can be thought of as a series of mail boxes, folders in a file cabinet, or some other metaphor where information can be located in a variety of places.. With some types of memory devices, the address in which certain data is stored can be called up by means of parallel data lines in a digital circuit (we'll discuss this in more detail later in this lesson).. With other types of devices, data is addressed in terms of an actual physical location on the surface of some type of media (the tracks and sectors of circular computer disks, for instance).. However, some memory devices such as magnetic tapes have a one-dimensional type of data addressing: if you want to play your favorite song in the middle of a cassette tape album, you have to fast-forward to that spot in the tape, arriving at the proper spot by means of trial-and-error, judging the approximate area by means of a counter that keeps track of tape position, and/or by the amount of time it takes to get there from the beginning of the tape.

. Data on digital storage devices can be more susceptible to damage through disaster than other record formats, such as paper or microforms.. Relatively minor damage to digital storage devices can easily render all information contained on a storage device inaccessible.

IS&T's NIP21 Conference
. As in 2005, NIP will be held in conjunction with Digital Fabrication 2006, a new conference that explores the potential of digital printing technologies with new applications and materials that go well beyond traditional printing and have been used to produce MEMS and electronic devices.
DIGITAL DOCUMENT QUARTERLY
. Both magnetic and optical disks are essentially 2-dimensional storage devices.
Cornell University Nomadic Digital Libraries: Proposal
. Arms, Carl Lagoze Department of Computer Science September 20, 1999 Research Objective The Cornell Digital Library Research Group requests support from Intel Corporation for research to extend digital library technology beyond the desktop and server to the broad spectrum of nomadic computing devices.. The overall objective is to create a nomadic digital library that is responsive to an individual's current environment, including differing computing devices, communications capabilities, and information needs.. In practice, people increasingly use a variety of computing devices in their daily lives not all of which are continuously connected to a network.. This growth of palm devices, hand-held computers, disconnected laptops, and embedded processors ( e.g.. Our hypothesis is that new software tools will enable individuals to exploit the mobility of these devices while using them for storage, access, and update of selected information resources, even when network access is impractical or impossible.

. Digital reformatting requires encoding, applications software, operating systems, hardware, driver devices, and possibly a network to display the reformatted image.. They also serve as Michigan's "hedge against the future." Instead of adapting the files to fit current limitations associated with bandwidth and viewing devices, the TIFFs remain information-rich, master files that can be migrated when new, and perhaps better, file formats or compression schemes become available.

1997 . Additionally, 8-bit-per-color digital capture might be adequate for visual representation on today's output devices, but it might not be sufficient to represent all the tonal subtleties of the original.. Depending on the quality criteria of the project, a more sophisticated system, and more expertise by the operator, are needed to successfully digitize a collection in an archival environment where future output devices are not yet known.. The characteristics of scanning devices such as optical resolution, dynamic range, registration of color channels, bit-depth, noise characteristics, and quantization controls need to be carefully evaluated with consideration of the future uses of the digital images.. Having an objective tool to compare different scanning devices will become increasingly important.. Scanning devices should be very well characterized spectrally, and the information should be readily available from the manufacturers.. Having to communicate only one color space (or profile) to the end user would facilitate optimal rendering of all images across all platforms and devices.
Guidelines for Digitization: Chapter 6, Digital Preservation
. Data Transportation Generally, moving digital information is handled by portable storage devices such as recordable CDs (compact disks) and more recently by DVDs (Digital Video Disks or Digital Versatile Disks).. As noted above, CDs and DVDs hold immense amounts of data, and it is unlikely that contents lists on the jewel cases will be palatable in the long-run, as more and more storage devices are used.

. Because the real goal is access to the discs' contents, not merely the preservation of the discs - the survival of playback hardware devices and software formats is key.. All types of CD players are electromechanical devices with complex moving, parts that must operate within very close tolerances, and it is easy for misalignments or other troubles to occur.. Another distinguishing feature of Kodak writable CD products is the presence of a unique serial number, both in numerals for a person to read and as a bar code that can be read by certain player devices.

Digital Imaging '05 Agenda
. The impact of devices such as Media Center PCs, multi-room PVRs, Wi-Fi image capture devices, media servers, and portable media players on traditional viewing models will be nothing short of revolutionary.
Film and Processing Forum: analog vs. digital color print permanence
. Assuming the media is still bonded to the substrate and no magnetic anomalies have affected any magnetic media and no EMPs or cosmic rays have affected any Flash cards, they then have to locate devices that can still read this media.

. Not only can digital storage devices be damaged by magnetic fields, viruses and equipment malfunction, but rapid changes in technology tend to make the devices and their file formats obsolete.. The number of output devices has increased dramatically, and the different materials being used vary widely in both their composition and response to environmental factors.
