General remarks on digital
image and video recording
Although digital conversion takes place in
a very high-value procedure, minor con-
version losses and picture distortions
cannot be excluded given the state of
technology; all memory saving jpg image
saving procedures, are liable for the defect
of edge deformation, i.e. sharp colour
transitions appear washed out under slight
enlargement. At the same time, metallically
reflecting scenes are often provided with
the smallest pixels, which were not visible
in the original, through the compression
procedure.
Besides, there are basic losses during the
initial conversion of the analogous video
signal into a digital value. Depending upon
the bit depth of the converter, important
details can disappear: out of dark, “margi-
nal” scenes of the original on the monitor
during inspection, possibly only a dark
black without statement is saved in princi-
ple according to a specified “1 or 0” pattern.
Note carefully:
:: Digital image data are not secure against
illegal manipulation
:: Make sure that you are able to reliably
retrieve the obtained image data 10
years after the inspection and you are
able to reproduce it faultlessly!
:: Adhere to the technical data sheets for
lasting care and safekeeping of the
storage media.
