3.6 How to Maximize Image Quality
„Image Quality“ is always a relative term. However, the definition of
quality really depends on the requirements of the application in
question.
3.6.1 Lens
The video lens has a significant influence on the picture quality. Refer
to section 3.6 for selection of an appropriate lens.
In any case you should use a high quality lens.
PHYTEC offers high-quality lenses from Pentax.
If you have a special requirement profile we recommend lenses from
Schneider Kreuznach.
We will be happy to advise you on the selection of an appropriate
lens.
3.6.2 Lighting
With image processing applications the selection of the right lighting
plays a major role.
Ideally the lighting will illuminate the object evenly and with high
contrast. Undesired structures (shadow, and overexposed areas)
should therefore occur as little as possible in the picture.
Correct lighting can drastically reduce processing times in many
applications. For industrial image processing a series of special
lighting techniques have been developed that can increase picture
display quality in various applications.
