ClearView
Workstation Description
ClearView is a user-friendly,
non-computerized, workstation
designed to improve the clarity of video recorded
images. VCR tapes are readily
enhanced to improve perpetrator identification and other characteristics of
interest. ClearView can be
interfaced to today’s TV output from desktop and laptop computers.
Commonly
Encountered Problems with Video Recorded Images.
Recorded crime scenes, surveillance, and industrial security videos obtained by
the investigator are often characterized by one or more of the following
conditions:
|
Condition
|
Consequence
|
|
low
light level
|
dark
scenes
|
|
perpetrator
blurred - running
|
blurry
images due to motion blur
|
|
synchronization
problems
|
wavy
video lines – distorted images
|
|
time
lapse field recorded video
|
incoherent
images – two different scenes at two different times interlaced into
one image, a frame
|
|
incorrect
azimuth on playback
|
garbled
image- ghost type double images like blur though incorrect azimuth
selection, normally
a GYYR VCR long play recorded tape
|
|

copy-not an original
edited tape
|

|
16

|
random
sequence of images difficult to
comprehend
the incident without demultiplexer

ClearView’s Advantage
ClearView overcomes the above conditions.
The investigator/ technical services officer can advance through the VCR
tape image by image, either via jog shuttle or field advance.
The brightness and contrast of poor quality VCR images can be adjusted to
enhance the likelihood of positive perpetrator identification.
Intensity adjustment can be accomplished in either color or gray shades
(the luminance signal only). Images
can be freeze framed, three fields at a time for the reduction of motion blur
and long time viewing without tape degradation (set the VCR to stop, the image
remains on the monitor).
ClearView
can be used to view time lapse or continuous recorded tapes field by field,
partial field by partial field, with precision control.
Full frame time base corrections are automatically accomplished during
playback eliminating or reducing wavy distortion. ClearView displays each and
every recorded image or partial image regardless the quality of synchronization
signals.
ClearView
provides dye sublimation hardcopy at a cost effective level, color or black and
white, acceptable to both the investigator and the courtroom.
ClearView allows the preparation of high resolution copy tapes with all
the above features; intensity adjustments in both color and gray scale, time
base correction, and tracking optimization.
The copies are better than the originals, enhanced not edited.
ClearView
allows use of the SVHS and VHS pathways with or without chrominance termination. The SVHS pathway provides a wider band path for the video
signal, even though the signal is VHS luminance (black and white signal).
This feature provides resolution enhancement, sharper and clearer images.
ClearView
can be interfaced to the video output of desk top or laptop computers via the
VHS or SVHS connectors. ClearView’s
Direct Connect Patch Panel provides for stereo audio, VHS, and SVHS Input/Output
with sufficient room for additional video equipment, i.e. camcorders, in house
existing VCR equipment, etc. ClearView’s
Direct Connect Patch Panel eliminates the cross talk between channels with
electronic video/audio switchers.
ClearView’s high resolution monitor can display VHS, SVHS, SECAM, and PAL
images. The monitor has over scan
and under scan allowing detection of copy tapes by the bright white tadpole spot
bottom line characteristic. This
copy tape or original tape characteristic can also be printed.
The printer’s output can be viewed on the monitor for final adjustment
prior to printing by push button channel selection.
ClearView can demultiplex three of the most popular digital recording
formats; Sensormatics Robot, Dedicated
Micro Sprite, and Pelco.
ClearView
can prepare copies of slow play or
long play time lapse video tapes as Quasi real-time in normal two (2) hour mode.
This feature is a significant aid to viewing these difficult videos.
The jury has the right to view the original evidence, even if it is
difficult to comprehend. Quasi
real-time copies, enhanced, are more comfortable for
jury understanding.
ClearView
is configured using double wide 19” EIA racks on a rolling cart with a slide
out writing table drawer. The
entire workstation can be easily moved and provides an excellent interview
room/courtroom display system.
