CCD - The
abbreviation for "charge-couple-device" and is often referred
to as a "chip". The chip converts visible light into an
electronic signal, which the digital image device
(camera/camcorder/scanner) reads. Higher end,
professional,
digital devices, almost without exception, have three CCDs, one for
each primary color. The colors on professional three-CCD image
capturing devices are much brighter, vivid, lifelike, and accurate than
the colors of one-CCD or two CCD devices. A three-CCD device
almost always beats out a one or two CCD devices, and the
difference in quality is normally instantly noticeable.
CROPPING - Eliminating (Cutting out) unwanted areas
of an image. Unwanted areas may include edges of scanned
photos / slides or elimination of unwanted surroundings, persons,
objects or backgrounds.
See Example
-
DEE (Digital DEE™) - "Dynamic Exposure Extender" Digital DEE helps
reveal details hidden in shadows and highlights. It compensates for both
underexposure and overexposure.
See Example
-
DPI - "Dots Per Inch" is a linear
measurement of the number of individual dots that can be
produced within a linear one-inch space. If only one
value is supplied then it is implied that the horizontal and
vertical values are the same; even though this may not be a
correct assumption.
-
EIGHT (8)mm FILM - 8mm, frequently called double 8, in reality was a special 16mm
film which had double the number of perforations on both sides. The film was ran through the camera to expose one side
and then reloaded (flipped over) and the other side was then exposed.
Once developed; the laboratory would split the film, lengthwise, and splice end to end
thereby yielding fifty feet of 8mm movies.
-
GEM (Digital GEM™) - "Grain Equalization & Management"
Digital GEM™ reduces the effects of film grain The resulting images are sharp, clear and
devoid of grain clumping or graininess.
See Example
-
GIF - "Graphics Interchange Format" - A digital
image format commonly used on Web sites. GIFs are
compressed files, which reduces the amount of time it takes to
transfer data via the internet. A GIF file employs
lossless data compression so that the file size of an image may
be reduced without degrading the visual quality where transparency is needed.- a single
pixel color can be assigned as a transparent area allowing the
background to show through. Black and white photos. Normally used for diagrams, buttons,
etc.
-
ICE (Digital
ICE ™) - "Image Correction &
Enhancement" Digital ICE™ removes
defects or scratches on the surface of the film with out losing any details
or any other elements of the original image.
See Example
-
JPEG - "Joint Photographic Experts Group" The JPEG compression standard is capable of producing high compression ration while maintaining
image quality. JPEG is a widely supported image file
format.
JPEG is a "lossy" format; therefore, some quality is loss when
an image is compressed. JPEGs like, GIFs, are
cross-platform; therefore, can be viewed on both Mac & IBM
compatible systems.
-
MEGA PIXEL - One Mega Pixel equals one million pixels.
Digital equipment manufactures and salespeople use the word mega
rather than million when describing the pixel density of a
digital camera’s/camcorder's/scanner's image sensor chip.
(e.g. a five mega pixel camera is easier to promote than a five
million pixel).
-
MULTI-SAMPLE SCANNING - Multi-sample scanning helps produce rich, noise-free images.
Multi-sample scanning removes virtually all the noise that can appear after
only one scan. By making as many as 16 passes, it ensures faithful
reproduction with smoother gradation.
See Example
-
NOISE - Noise, normally, appears
as blackish / grayish spots, lint or dirty, trashy areas and
may be best described, by us old timers, as "snow". Snow
was common on the older analogue televisions, the weaker the
signal the more snow on the image being projected. The
signal strength could be affected by numerous things such as
electrical interference, temperature and equipment
(television's tuner, antenna, cables, etc.).
-
PIXEL - The word "Pixel" derives from "Picture Element". In digital
imaging, and in the simplest of terms, a pixel is a dot. However,
this is the simplest of terms because a dot may consist of several sub-pixels.
-
PPI - "Pixels per inch" The total number of pixels in
an inch (horizontal and vertical directions). PPI may be used to
describe the resolution of a scanner or digital camera.
-
RESOLUTION - The number of pixels that make up
an electronic image in a given area of an image; such as
pixels per inch or pixels per centimeter. High resolution
is the term for an image with a lot of pixels in a given area;
therefore, low resolutions would mean that there are not many pixels in a given area.
-
ROC - "Restoration Of Color"
Digital ROC™ brings faded color
of old films or slides back to life. Enjoy vibrant, faithfully rendered
images.
-
SCAN IMAGE ENHANCER - Scan Image Enhancer provides one-touch image correction.
Automatic brightness and color saturation adjustments with no complicated
control settings, make it easy to produce images with optimal contrast.
-
SIXTEEN (16)mm FILM - Initially developed by Eastman Kodak as a
reasonably priced alternative to the theatrically used 35mm. The
average amateur still found the 16mm very expensive. Reportedly; the camera, projector and tripod
package could be purchased for $335 and at a time that a new Ford
automobile could be purchased for $550. Read More
-
SLIDESHOWS - A slideshow is the arrangement of pictures,
one behind the other. The pictures can placed into
chapters (groups) so they carry the same theme (i.e. are in the
same time frame, part of the same function or event, etc.). Once grouped the chapters can be
timed for viewing, have music and/or transitions added.
The presentation can be burned onto a DVD or even transferred
onto a VHS tape for easy viewing.
-
SUPER 8mm FILM - The Super 8mm camera was equipped with a light
filter. The cartridge was molded plastic. The film
was one continuous length and did not require reloading (flipping).
The sprocket holes were reduced in size which provided approximately 50%
more image area than the 8mm. The perforations were moved to the center of the
film frame rather than the corner. Read

TIFF - "Tagged Image File Format" - "TIFF", ".tiff" and ".tif", files contain
bit-mapped data. In addition to being a widely supported
format, TIFF is able to handle the color palette needed for
professional-quality images and graphics.
